Hi Org users,
I need to get control over the time I spent on developing
Org-mode. Recently, I have again worked too hard on it, spending
more time than I should, in order to get 6.9 and 6.10 out and to
seize the chance to get the best possible version into Emacs
23.1.
However, this is getting out of control, and I am now putting
myself a hard limit of 1 hour per day, clocked by Org-mode, which
will clearly cut in on my development speed and posting rate.
Here is how you can help me to make the most of that one hour.
1. If you report a bug, please try to do as much work as you can
yourself. Before you send it, think if you have collected all
the information you can. There are great examples of good bug
reports on the list already. The best bug reports are, of
course, those that are accompanied by a patch.
2. If you are reading the list and see bug reports, consider
putting in 10 minutes, trying to reproduce this problem
yourself, and maybe adding information that might be useful
for me to track down that bug. Again, this is already
happening, I am only trying to encourage this type of
behavior.
3. I have recently spent much time on fixing bugs in parts of Org
that I did not write myself, so this is taking much more time
than usually. If you know Emacs Lisp, and I know there are a
number of excellent Lisp programmers on this group, consider
"adopting" one of the following subsystems. By "adoption", I
mean that you make it your mission to deeply understand this
part of Org, so that *you* will be in the position to fix
bugs, taking that off my shoulders.
- org-publish.el. I think the biggest bugs are out now, but I
am sure this system can be improved quite a bit. If you are
that Lisp programmer trying to take up this task, consider
teaming up with Sebastian Rose who is a great guy, has quite
some understanding of that system and good ideas about it,
but just is not enough of a Lisp programmer to really take
that on.
- org-export-latex.el. This is a tough one because you need
to know both LaTeX and Lisp. And the code is complex, in
part because Org-mode allows to write LaTeX is a relatively
lazy way. Bastien has done a great great job capturing this
into an exporter. However, there are still problems and
bugs, some came up recently on the list. And Bastien
currently does not have the time to contribute consistently.
As a result, I have started to fix some bugs, but this is
really eating too much of my time. This subsystem can also
use feature additions, for example better handling of image
insertion, maybe with captions. I have ideas about this, so
talk to me if you want to help out.
4. Try to answer as many messages on the mailing list as you can.
I have been trying hard to make sure that each and every
reasonable question on the list (and this is really the only
kind we get in this amazing community) will be answered.
Doing this still takes a significant fraction of my Org-mode
development time. I will clearly spend less time on this in
the future, in this way also giving others more time to
answer. Again, there are already quite a few people who
regularly *answer* questions, and all I am trying to do here
is encouraging this activity.
5. Help developing the Org-mode FAQ by adding useful information
to it yourself. All you need to do is to get acces to Worg,
which will help getting to know git in the process. Worg is
meant to be user edited, so please go wild and add information
and links at will.
Thanks to you all, for your understanding and help.
- Carsten

It is quite a challenge to try out and understand numerous features
and facilities already in Org and the pace at which the new changes
were coming was unreal and super-human. The backlog of things I
wanted to try, understand and absorb in my workflow was consistently
increasing. This is not a complaint; I am having so much fun. *BUT*
I do not want my favourite developer of my favourite package in my
favourite editor to burn out. Please do take it easy.
Unfortunately, I can not help with #3 (adopting a subsystem) since I
am Lisp-challenged but with rest I will.
Sincere thanks for all your time, effort and sacrifices.

Should we put a page on worg by this name (see subject of this
thread)? We could show, how to turn on debugging, write a good bug
report, link to good elisp tutorials and describe how to use the elisp
debugger in emacs for simple debugging.
If no one stops me, I'll do it these days. As or me, a page like that
would be helpfull. I'll be back for report - maybe one of the lisp
freaks could add some details later on?

Hm - there is a link to the 'Feedback' section of the manual
(http://orgmode.org/org.html#Feedback) on
http://orgmode.org/worg/org-contribute.php but
1. It's hard to find. One has find worg (http://orgmode.org/worg/),
and then click 'How to contribute to Org?' to get to
http://orgmode.org/worg/org-contribute.php where the link is.
I think I wouldn't follow the link 'How to contribute to Org', if
I was to report a bug (maybe it's my bad english, but I lots of
people whos english is even worse).
2. While the 'Feedback' section in the manual is as good as the rest
of it, it's short and does, for good reasons, not provide more
information, than absolutely needed.
Suggestions:
1. on Worgs startpage (http://orgmode.org/worg/): add an extra section
(as the FIRST one) 'How you can help'.
2. Under that headline, put the link to the 'Feedback' section of the
manual.
3. Add more links to one or more pages for tips on debugging etc.
4. Add subdirectory for those debugging tips. We could also add things
like coding conventions, notes about the APIs in org etc. to that
directory.
....Please comment...
5. I also think of little packages for testing parts of org.
Example XHTML-export:
When the HTML-exporter didn't work lately, I set up a little
directory or testing. On top of that tree I had an Org-file with
[[elisp:]] links to click on, like
[[elisp:(setq debug-on-error t)]]
or [[elisp:(debug-on-entry 'org-export-org-to)]] and one for
loading a setup.el in the same directory (primaryly to adjust
org-publish-project-alist - in principle, everything could be
setup in that file, but needed two different setups for these
tests).
Now I can just open that Org-file, click on two or three links
and get a backtrace, if something is wrong. It's so simple to
test the exporter this way, that it takes 30 seconds or even less
(on failure :-)
With simple trees like that (eventually downloadable as *.tar.bz2)
one may test a module with all the little corner cases, which
might not be in the Org-files the tester uses for his daily work
and without risk.
If we encounter a new corner case, we could just add it to the
test packages Org-files and document it in the packages index.org
(or README.org) to prevent a regression.
When working on a module, one could programm against those tests.
Creating and maintaining those test packages is a simple thing to do.
All it requires is knowledge of USING org and just a tiny little extra.
Hence I suppose this work should be done by the community/worgers.
It will be much more fun to add tested patches (and more secure to
create one)!

Sebastian

I'm curious if you or someone else has any ideas for writing automated
tests for org-mode. I haven't the foggiest idea how someone would
write a test for the parts of org that control what is displayed on
the screen. I mean, when the bug is 'it doesn't look right' how can
you tell?
Perhaps the git repository should have a small collection of small org-
mode files that reproduce certain bugs? If there were some examples
of how to create such a test, then perhaps bug reporters would find it
much easier to create them.
I do see some confusing issues due to different configuration files.
So creating a test file might involve making sure org-mode doesn't
read any configuration (how do you do that?) and possible asking org-
mode to extract all the configuration variables it has right now and
dump them into a test file (...and how do you do that?)

Running a minimal emacs should suppress custom config files:
emacs -q -l yourtest.el
Some kind of regression testing framework would be awesome. Org-mode is
large enough that this is almost a necessity to keep things stable and
bug-free.
Maybe something can be put together from the git testing framework and
use of emacs -batch to process test org files and verify the output is
as expected (with diff or some other tool).

Hi Ben,
I cc'ed the list.
The tests I described in my email to the list are not automated. The
reason for that is my lack of (e)lisp knowledge.
BUT, they where easy to handle for non programmers. I think the little
test will make it to the worg site this week, when all private data is
removed. You could take a look at it by then. And: improve, improve,
improve... :-)
If you know of someone who knows how to do automated tests in elisp, or
some technique, package, whatever, please post it to the list, so we all
can take a look at it and comment->decide something. This is _highly_
_appreciated_.

Believe me, my idea is the foggiest of all possible ideas ;-) (so where
my ideas of JavaScript some mounth ago), so I won't be of much help, I
fear.

YES! Exactly. Every corner case an Org-file, every bug an Org-file.
_DATA_ for testing is something, everyone _can_ provide.
But git later, yes, maybe.
Since this would need Carsten to think and act on this, I feel Worg is a
nice place to start the first expieriments. We need Carstens power for
other things (when will Org-mode finaly wash my car? It's repeater-TODO,
but nothing happens!!!)
Basically, I'd try to keep the the testing as simple as possible, and
try to get elisp programmers to help with the code. We should try to
keep the hurdles for testers as humble (?) as possible, and put all
that's needed to be helpfull on one page in worg.
I recently discovered the very unautomated `(print object)' in the elisp
reference. Not everything can be done automated, maybe, but if I would
have known this stupid `print' function, I would know more about elisp
and some files in org already. And it would have been faster and easier
to create the two minor patches I wrote. This is, where the 'links to
elisp tutorials', 'tipps and tricks', 'emacs debugger' come handy.
Willingness to help is no problem, as the Org-community reveals. As for
me, it's often a lack of time and/or knowledge, that prevents it.
And the aim of all this is to help helping, in means of good and
detailed bug reports in the first place.

True.
Hm - to test without configuration, we already have `emacs -q'.
Dumping the variables is just a list of (print var) statements. A
(quite) complete list of variables could be extracted with grep?
e.g.:
grep -r defvar lisp/
Once we have such a list, we could set/reset some/all variables.
This will not be perfect, but could work reasonable well.
And yes, it would indeed be nice, to have elisp to reliably reset
emacs/org configuration, so one could do several different test in
sequence. Preferably they would _always_ run and dump all errors to some
file or buffer, even if one or more tests fail.
I think elsip provides funtionalities to handle those errors and skip to
the next test. This would be a huge step.
But still, we have to test with different _DATA_ too! The test I
described is just a quick hack I did to do the testing, while Carsten
was bug-hunting on the other end of my internet connection.
The XHTML-export test was much easier to do, then some other tests we
might need. In the end, it was a test, automated or not. And I had to do
it, because I'm one out of a few who use org to maintain a web-site
(locally in my case) and export an entire directory tree with lots of
_DATA_, use org-info.js, `#+SETUPFILE' lines, etc. , I believe. This
became obvious in this case. I was the one who even noticed the bug,
which means, no one else was using recursive XHTML export for a while,
or their setup didn't reveal that bug.
So clearly I was the one to provide some support for this very part of
the system. I can't rely on the assumption, that some maintainer has all
possible setups at hand all the time (maybe this was possible years
ago).
While the testing of the HTML-export was quite simple, it requires a lot
of _DATA_. Namly files and directories + different setups, per file
setups, #+SETUPFILE, images, with/without org-info.js, extra styles set
or not... to have a realistic testing environment (the test didn't have
all of these...).
A summary could be, that it's nice to provide different setups for
maintainers and testers.
- *Easy to install* (unpack and done),
- *easy to use* ('emacs -q' and click a few [[elisp:]] links to set
everything up)
- and *easy to download* once they are removed again (a central place on
Worg).
- *Corner cases*, like the 'empty line before first heading bug' in the
LaTeX exporter recently.

To: Sebastian Rose; +Cc: emacs-orgmode Org-Mode
Well, I was just looking at http://www.emacswiki.org/emacs-fr/UnitTesting
Unfortunately for me, I can't tell if Emacs comes with any builtin
framework already, so I downloaded one of the many options listed on
that page to my local site-lisp directory: http://www.wanglianghome.org/svn/test/test.el
The personal issue I have is that I'm on a Mac, using Aquamacs, and
the command line version of emacs is a different binary, so there
might be trouble when a test passes at the command line, but fails
where it matters to me. I don't even make sure that org-mode is up to
date at the command line. I thought it wasn't, but I just checked and
now it is. Plus, I don't really understand internals of emacs (like
basic internals: I understand point and mark, buffer and file, but not
transient mark, indirect buffer, symbols vs strings, window vs tab vs
frame)
The tutorial I'd need to write a test is one which lays out code I
could copy and paste to do the following
* setup the test environment
- create a test directory
- create a sample test.org file
- put the cursor in a particular place
* run the command we need to test
- hit the 'TAB' key, or C-c C-c (some folks might need to be
reminded how to find out exactly what command is actually being run
when you hit a keystroke. And some of me might need to be told what
lisp-code to use when the keystroke runs different commands at
different places in a file)
- reformat a table
- clock in/out
- create the agenda
- export .html .ics .dvi file
* How do we specify the correct result???
- check that the headline folded properly. What's the lisp code
for getting the folded string as displayed?
- check that the cursor is where it should be? especially when the
cursor is near elipses...
- check that the agenda is built properly. What's the lisp code
for getting the agenda as a string?
- check that the exported files are correct. Maybe the right
suggestion is to run the export on two different files, so the test
can focus on the 'diff' between them. That way different people who
run the same test on different hosts can get the same result.
More experienced folks must suggest whether it's better to have the
expectation of a test be specified as a string in the test code or as
a separate file in the test directory. It might depend on context, so
feel free to lay out three or four cases.
If even one kind of test for each of these 'cases' exists, hopefully
we can encourage people to report bugs with the test. I mean, if
people are already going through the effort to create the small sample
org file to demonstrate their bug, and it's only a short (obvious)
step to translating their english description of what should happen
into equivalent lisp code.... that seems like a big temptation for
someone to do it.
Plus it might help them convince themselves that it really is a bug,
and not that they are going crazy.
I gotta move on for the day here, but I'll keep thinking a bit about
this.

Hey, diff is a good idea!!
I didn't take the verification of the output into account yet :-)
I just pushed a change of Worgs start page, and added a directory
'org-tests'. I've placed an index.org there, which now is just a
collection of ideas (I'm on my day job, so I can't really work on it
now).
Don't know how often the git repo is published.
Bernt and Ben, are you 'worgers' allready?
Do you think it makes sense to add snippets and ideas to the new page in
Worg? I think while the list great to exchange ideas, it's good to have
a place, where all those ideas are destilled to one-liners.
Cheers,

Hi,
I'd recommend ert.el, it is actively maintained, and I have it on good
authority that this the tool of choice for elisp unit testing.
http://github.com/ohler/ert/tree/master
,----[from ert.el]
| ;;; Commentary:
|
| ;; ERT is a tool for automated testing in Emacs Lisp. Its main
| ;; features are facilities for defining and running test cases and
| ;; reporting the results as well as for debugging test failures
| ;; interactively.
| ;;
| ;; The main entry points are `ert-deftest', which is similar to
| ;; `defun' but defines a test, and `ert-run-tests-interactively',
| ;; which runs tests and offers an interactive interface for inspecting
| ;; results and debugging. There is also `ert-run-tests-batch' for
| ;; non-interactive use.
| ;;
| ;; The body of `ert-deftest' forms resembles a function body, but the
| ;; additional operators `should', `should-not' and `should-error' are
| ;; available. `should' is similar to cl's `assert', but signals a
| ;; different error when its condition is violated that is caught and
| ;; processed by ERT. In addition, it analyzes its argument form and
| ;; records information that helps debugging (`assert' tries to do
| ;; something similar when its second argument SHOW-ARGS is true, but

Actually, if you want, you *can* run Aquamacs from the command line, but
it can be a pain to do it. I figured out how to do this when I was
trying to use the Makefile for org-mode. I ended up with the following
emacs command-line:
EMACS=/Applications/Aquamacs\ Emacs.app/Contents/MacOS/Aquamacs\ Emacs
and this line for batchmode compiling. Note that I had to augment the
standard emacs command-line -q option with Aquamacs' -Q:
BATCH=$(EMACS) -batch -Q -q -eval \
"(progn (add-to-list (quote load-path) (expand-file-name \"./lisp/\")) \
(add-to-list (quote load-path) \"$(lispdir)\"))"

I've been considering buckling down and doing some more ELisp coding,
which would mean org-mode coding because I've become ridiculously
dependent on org-mode. If I do, I would only do it in a test-first
way, because that's the only way I'll write code anymore; so it would
definitely be good to know that unit tests will be be accepted into
the codebase. Personally, if I did this I think I would like to use
Emacs Lisp Expectations:
http://www.emacswiki.org/cgi-bin/emacs/EmacsLispExpectations
I'm a big fan of Jay Field's work, I like the way the original
Expectations for Ruby is structured, and I like the looks of the EL
Expectations API. I'm open to other libraries though - so long as
SOME unit-testing standard it accepted.

Ben,
I added this to the new page on worg. Please tell me: is it OK for you,
if I simply add your ideas there??
What do the others think?

Please, if you find time, add the rest somewhere there?
If not, I'll take a closer look tonight and check in what's interesting
(which seems to be all of it, actually).
http://www.emacswiki.org/emacs-fr/UnitTesting:
Does this mean to add code to Org's *.el files? This would mean a lot of
work for Carsten :-( OK, once done...
But:
sh> grep -r defun lisp/ | wc -l
1290
Checking in/out of every function makes 2580 places to check. I can't
estimate the effort, actually, because I never did Unit testing. I guess
this number much higher than needed?
Could anyone with testing expierience estimate?
While I think automated tests are a great thing to do and I'm happy to
see this reaction on the list :-), I still think we should also provide
the 'simple' tests without additional dependencies (when will package
management make it into emacs...). And I'd like to keep the effort and
impact for Carsten as small as possible. He will have to check each and
every patch because of feeling, and actually being, responsible for the
code.
Another question: will the code compile in emacs without the testing
framework installed? Probably yes.
Should we try to think of those 'simple test packages' as the more
_DATA_ part of other tests? This would mean one could code an automated
test without the need to create data too, since we have the data
seperated. Again, I'd like to keep the hurdles low for everyone
involved. When automated testing turns out to be a foolish easy and rock
solid, this could change.
* Three basic approaches:
1 Simple data and setup packages.
2 Code, that executes org commands and test for correct output,
no changes in Org's code needed.
3 Test framework with changes to Org's code.
I'd promote a combination from 1 and 2, and see, how far it goes.
DATA
+--- d1
+--- d2
+--- d3
TESTS
+---t-a
+---t-b
+---t-c
Now one would run test t-a over d1, d2, d3.
Still a programmer could use d1 to fix a bug in d1 and finally push the
fix for automated testing against d2 and d3.
bug X
tester verifies (is ist bug? how to reproduce...)
tester adds X to dX (message -> list or programmer)
programmer installs dX
programmer fixes bugX
programmer push (message -> list or tester)
tester tests against d1, d2, d3
where tester = [human|machine] preferable human (simplicity)
Should we track the dependencies between code and tests?
Suppose one has worked on a.el.
Shure more than one test has to run.
Example: org-publish.el contains code common to LaTeX-export,
HTML-export...

A few points, from someone with a decent amount of testing background:
* As someone who has contributed to OS projects, the lack of a
pre-existing set of regression tests in org-mode is actually *the*
most significant blocker to my getting involved in org-mode
development. I do all of my coding - both professional and personal -
in the context of tests, and not having the existing framework means
that before I can start working on new features I first need to spend
time yak-shaving on testing infrastructure.
* I think there's a lot of over-thinking going on here. Here's the
test-first coding discipline in a nutshell:
1. Identify a problem/missing feature.
2. Write a test (possibly using a unit-testing framework to help)
which will pass when the bug has been fixed or feature added. This can
be as simple as calling a function and validating its return value.
3. Run the test. Verify it FAILS.
4. Write code to make the test PASS.
5. Refactor, if you introduced any code duplication in step 4.
6. Run all the tests, to make sure you didn't break anything else.
7. Commit.
If someone would be so kind as to identify a small bug or feature, I
would be happy to demonstrate this workflow in the form of code, time
permitting.

Great! I hope so too!!
If slow, it's still no problem to run all those tests before a release
or once a day, whatever.
Glad to here your interested in keeping impact on Carsten low!

Sounds great! Not shure if we can provide a bug though :-D
Bug anyone?
Hm - how about:
1. A not yet existent elisp file test-worg.el, that defines a function
hello-worg, and a variable lang, and simply puts "Hello Worg"into the
minibuffer (if (string= lang "en")) and "Hallo Worg" (if (string= lang
"de")) ?
Did you work with unit-testing frameworks for elisp already?
Which one?
Recommendations?
Could say something about the effort to get started with such a
framework?
Can we add it without changing Org's code? If understand 2. correctly - yes?
If we can, would we loose quality/speed of tests?
How much?
Tell us all :-)
Oha - I have an appointment (concert) - back tonight!
All the best,

I'd prefer something that would be of concrete value to someone in
using org-mode - made-up scenarios tend to lead to unrealistic tests.

I have not. I've done test-driven development in Java, C#, Ruby, and
C++(!) though, and if I can do it in C++ I think I can get up to speed
in any language pretty quickly ;-)
> Recommendations?
As I said in another comment, I'm liking the look of Emacs Lisp
Expectations a *lot*. Partly because I think Jay Fields is bang on
the money for how maintain good habits in your tests, and partly
because it has a mocking framework to go with it. Testing without a
mocking framework is less fun than testing with. However, I haven't
actually used it yet, so I can't responsibly recommend it. Let's just
say that the discovery of it recently was the thing that got me
excited about doing some serious ELisp development.
> Could say something about the effort to get started with such a

I think if you have some *running* examples to crib from it shouldn't
take someone who is already ELisp-savvy more than a few hours to get
the hang of it.
>

In a dynamic language like ELisp, any testing framework that requires
you to change the code just to get it under test isn't worth using.
No, you should not have to change org-mode's code to get started with
tests.
That said, developing in concert with a test suite will definitely
tend to influence how you write the code. Generally speaking,
developing with tests encourages smaller functions which do one thing
and one thing alone and don't have a lot of non-obvious inputs and
outputs. Since this is usually the direction you *want* your code to
go in anyway, it's a virtuous cycle.

Ok, here's your chance. This is something that has bothered me for
quite some time, but I've never been able to reliably reproduce the
problem. And it's such a small issue.
Sometimes, when it looks like my cursor is at the end of a headline
and I hit tab, the headline does not cycle. Normally it does.
It hit me that the point was not on the headline, it only looked like
it.
So here's the sample test.org file
* First Headline
Some body text
* Second Headline
(goto-char 17) ;that's the end of the first line
(org-cycle)
At this point the buffer looks like:
* First Headline...
* Second Headline
(goto-char 25)
(org-cycle)
I think the buffer should look like this
* First Headline
Some body text
* Second Headline
but it still looks like:
* First Headline...
* Second Headline
* ABOUT THIS BEHAVIOR
I should be honest here. This may not be a bug.
As I created this test data, it became a bit more clear that exactly
where the cursor is matters a lot here. I *promise* that I've seen
this behavior even when the cursor shows up before the ellipses, but
in the test case I set up here, I could not make that happen. I also
found that if I used the key-chord M-x goto-char <RETURN> 25,
everything worked fine. The cursor stayed in front of the ellipses
and the tab key worked. But when I used M-: (goto-char 25) the cursor
moved to the same line as the ellipses, but after them. and the <TAB>
key stopped 'working'.
I finally figured this out while playing with git. I switched
branches at the command line and needed to perform a 'revert-buffer'.
This left the cursor before the ellipses, but unable to properly (org-
cycle) using the <TAB> key.
More experimenting.... I *think* the revert-buffer command tries to
keep point close to the same place, and the org buffer had automatic
folding. The bad thing about this for me is that I'll hit the <TAB>
key four times trying to make sure it's not just an empty tree.
Meanwhile, (org-cycle) has indented the first line of the body, but
hasn't shown me the text I'm changing. Then I get confused about why
the buffer needs saving, probably 10 minutes later when I've forgotten
all about hitting the tab key.
But I'm way out of my depth to try to understand the relationship
between (revert-buffer) (org-cycle) the arrow keys, and all. I just
hit M-< or S-<TAB> and try again. Or C-a, which sometimes works.
Sometimes I grab the mouse as a last resort.
* ABOUT TESTING ISSUES
Just from this example, I'm eager to understand:
1. How can we differentiate between where the cursor appears and the
value of point
2. How can we tell what the users sees on the screen versus what the
buffer contains
So the value of a testing framework is that this: if I'm going to
announce to the world that I can't get something to work, (like the
tab key), I'm going to make darn sure it's a real problem. I'm going
to spend the time to create a small sample file, that reliable creates
the problem, and I'm going to try a few different scenarios. But if
I start to get lost or confused about which settings I've fiddled with
or what is supposed to happen, I'll wander away from the problem and I
won't submit the bug. We all lose in that scenario. But if the
testing framework exists, and it is lightweight enough for novice
emacs users (advanced enough to use M-x but not advanced enough to
read lisp) then maybe I would have used it for this example.

For the record, I normally would never expect the user to submit
tests. A description of the problem and some sample data is all I
expect. Writing the a test to reproduce the behavior is the
programmer's responsibility as far as I'm concerned.

That's the best part of open source software! A surprising amount of
the time, the user IS a programmer, and thus is able to provide tests.
And it's not that we should require anyone to provide tests before
they report a bug, but they should be required to outline the steps to
reproduce the behavior, so any programmer could take 5 minutes and
quickly whip up a test.
ps: I almost have a baby ert framework for org-mode. It doesn't do
anything yet, but the design is you write a test, and add it to the
org-test-hook to be run by org-test-all.

[...]
As someone with also a decent amount of testing background, I'd like
to answer also.
> Did you work with unit-testing frameworks for elisp already?
> Which one?
I co-wrote regress.el (Wayne Mesard wrote the first version) and I
wrote rtest. I've written some testing for allout.el before I
switched over to org-mode (which is very nice, BTW, Carsten, and
provides pretty much everything I wish-listed for allout mode). Of
particular interest for testing org-mode, I wrote mockbuf.el, which mocks
files and buffers so that tests can deal with files without changing
anything permanently.
> Recommendations?
Hard for me to say objectively.
I prefer my rtest but it's in flux right now. I wouldn't recommend
the current public version, rtest 3.0 I've designed and half written a
better version but I can't really ask you to wait until I get around
to making a better version of rtest. There is a development version
that works and does nice things; it's messy as hell right now and I'm
embarrassed about that. It isn't public but I could put it up if
you'll forgive its messy state,
It has mockbuf, which I found indispensable in writing tests for
allout.el. In fact, I mostly developed it for that, though all the
allout-specific code is elsewhere. Also useful for writing tests:
safe-equal.el, caselet.el, and select.cl, all in the ancillary
directory.
I would steer clear of frameworks that provide many of synonyms for
equality tests, inequality tests, etc. You already know how to write
(not (equal ...)) in elisp. Why learn the name and syntax of
something like (shouldnt-be-equal A B)? Having a lot of that makes a
package LOOK heftier but doesn't do anything more for you. IMO
analyzing test failures should be done by inspecting the test form,
not by making you write things in non-standard elisp that could be
written in standard elisp.
Using ert would mean requiring ewoc, which means tests wouldn't work
on emacs 21. Too bad, because it has some appeal.
> Could say something about the effort to get started with such a
> framework?
For rtest, right now you just need (a) the development version, (b)
unzip it in your emacs-site-lisp or set the paths and autoloads
manually if you prefer, (c) include the following in a file to be
tested:
(when (not (fboundp 'rtest:deftest))
(defmacro rtest:deftest (&rest dummy))
(defmacro rtest:if-avail (&rest dummy)))
Then write tests as:
(rtest:deftest function-name
("Docstring"
(test-form) ;;Return a boolean
)
;;Repeat as wanted
)
That will get you started, but really you'd want to get familiar with
the stuff in mockbuf.el - which is so messy right now that I'm
embarrassed about it, because it contains both old and new versions of
many things in flux.
Other advice: Make a directory to hold short examples of files that
illustrate "before" and "after" states for the various
transformations. Each unit (eg org-agenda.el, org-archive.el etc)
should have its own subtree of examples.
One thing I'd do early is build the following test helper functions:
A macro that runs a test body inside a "let" of all the configuration
options set to expected values.
A function to compare vector-style strings. `equal' doesn't suffice.
rtest has, in ancillary/safe-equal.el, safe-equal-compare-objects and
safe-equal-compare-vectors, which IIRC suffice for this.
The ability to write only the visible parts to a separate buffer was
indispensable in testing allout's folding. You already have it in
org-export-visible with the type that keeps the buffer, "?\ ". Then
you can just compare contents.
You will likely have a lot of what I call "output tests", tests of
code that has the property that if the output looks right, it is
right.
IMO with output tests, you need to make it easy on yourself. TDD is
all well and fine, but not if it makes you repeat yourself. If there
is available output that looks right, capture it and use it as a base
for comparison. That's not "pure" but it's far easier and it works
right. If the available output isn't yet right, capture it anyways
and tweak it to make it right - but this rarely happens.
I automated that sort of thing for a Prolog test harness I wrote,
works fine. You'd just write a test of a special type that produced
and captured output. It would originally be ungraded, but you would
then grade it, and it would remember the correct output and compare
against it.
I was planning to add the same to rtest and I partly did, but never
finished it. Still on my todo list.

rtest's tests like to be in the same file as the code. If you use the
form above, the file still compiles and runs even when rtest is not
available.
It's possible to write the tests in another file, but then either
tests aren't grouped together (must be run one by one) or you have to
do extra work to group them. If they're in file, you can run every
test in a package with `rtest:library'. The other really convenient
way to run a test is rtest:defun-at-point.

Not at all.

PS: One more piece of advice: Make an auto-insert or at least a
skeleton that inserts test headers, like the "(when (not (fboundp ..."
stuff above. You'll be using it a fair bit, and it's real nice to
have it just automatically be there when you start a new file. This
advice is geared toward my way of working, though, with the test code
in the same file as the functional code.
