I am probably not the right person to suggest this, but I think it is time to introduce a test framework for org-mode, to ensure that the (without doubt useful) approach to develop org-mode does not lead to regressions. org is, as I see it, complex and is getting broader and broader - time management, task management, literate programming, recipes (I like the idea), all have different (possibly contradicting?) requirements. And I think it is getting more and more difficult for new contributors to have the overview to make sure that something they are contributing actually does not break something else. As I think it would be *really bad* idea to split org, I think that it needs to be assured that no regressions are introduced. Unfortunately I have no idea about elisp and can therefore not contribute to the framework itself, but I guess all of us could contribute small org files as test cases and expected resulting outputs (exports, tangling, agenda files, ...). If the framework could accommodate those, everybody could help to bring together a (definitely not perfect) test framework, that would bring org at least one step closer to error-free growth. I have to add I really love org and babel and have no idea what I would use instead for literal programming in R. Cheers, Rainer - -- Rainer M.

Yup, what you would need is some org source files that exercise all of the possible export options (for testing export, for example), including weird edge cases, and then ERT (if that's what we ended up using) would provide handy functions for making sure the export output matches expectations. The excellent gentleman who created the ODT exporter, whose name currently escapes me, has already created test files for his exporter—that would be a perfect place to start. Covering all of org's various functions would end up being a bit of a PITA, though you're quite right that it's an excellent idea, and will become more and more necessary.

It could be useful to have this kind of framework for org but I think it is difficult problem when it comes to org export. For example, is removing the "validate xhtml" button from an html export make this export invalid?

I think the “automated” part refers to running the tests. What you suggest—having a set of files that you could manually export to verify the results—wouldn’t be of much help, IMHO. First, it’d require a lot more time than executing a single command and checking the summary at the end. Second, it’d be very error-prone. A comprehensive automated test suite gives people writing patches an easier way to perform regression testing and catch any unintended consequences. On the other hand, it /does/ take a lot of effort to keep it in sync with the codebase… maybe we need a Test Fairy. ;-) Aankhen ^ permalink raw reply [flat|nested] 15+ messages in thread

Just a general commitment to convert problem reports from the mailing list into unit tests should be a step in the right direction.

I have a possibly completely useless idea regarding "automatically" checking regressions. As far I understand the problem now is its not very feasible to do automated tests with what ever test suite we have (or will have after the improvements) and see the exported results for each patch, as at some step it involves human intervention (as in, was the export good). So maybe we can have a directory on the Worg website (not part of the Worg git repo) where every week or so the test suites will publish with what ever the org-mode head is at the time for all the supported formats. Then us "puny lisp illiterate" users can check up on it over the course of the week and report back to the list if there is a problem. Since this way people can look at the export formats they are interested in, none of the formats get treated like a step child either. Would that be feasible?

There are already fully automated tests which (e.g., export to some backend like html or tex and then programatically check for properties of the exported results. It is certainly likely that I am missing something, but I can't think of a situation or a feature of Org-mode which could not be tested under the current setup (mainly due to the fact that *every* user action in Emacs reduces to a series of function calls which could be programatically recreated). > > So maybe we can have a directory on the Worg website (not part of the > Worg git repo) where every week or so the test suites will publish with > what ever the org-mode head is at the time for all the supported > formats.

Would that be feasible? Or did I completely misunderstand the > problem at hand? I'd think that a better way for contributing to the test suite in a non-lisp manner would be to submit test cases, e.g. "this block of Org-mode text should export to this but sometimes instead exports to this", or "when I press this key sequence in this place in this org-mode text I expect x to happen to the text". We could even potentially leverage the existing Emacs macro system to build a *record* method so that users could semi-automatically record their actions allowing an interactive method of recording tests (or submitting a re-creatable bug report). Or at least recording enough information so that someone with a little bit more elisp-fu could wrap the recorded actions into a unit test.

Good or not good is subjective - but *consistent* is not - and consistency is important. Even if I do not like the default LaTeX output from org, I can tweak it, but there is a problem if there are unexpected changes in the export, which break my customizations or make it difficult to recreate old documents, especially if these changes are not documented. >> > > I would disagree that we need user interaction in the test suite.

Exactly - the tests is R work this way: you have some code which is executed, and then the resulting *output* is redirected into a file. these results are then compared to a reference output, and if they are not *identical* an error is raised. Similar could be done in org: export to LaTeX should always result in the same output, unless a change is intended (e.g. additional headers, improvements, ...). So one could compare the resulting .tex file with a reference .tex file for this test automatically, without user intervention. > > It is certainly likely that I am missing something, but I can't think of > a situation or a feature of Org-mode which could not be tested under the > current setup (mainly due to the fact that *every* user action in Emacs > reduces to a series of function calls which could be programatically > recreated). > >> >> So maybe we can have a directory on the Worg website (not part of the >> Worg git repo) where every week or so the test suites will publish with >> what ever the org-mode head is at the time for all the supported >> formats.

Correct - this is what we would, in addition to programmatic tests of individual functions, need. I would actually say that the exports / tangling / agendas / ... are the possibly the more important test cases, as they 1) only show in a later stage of ones project, and 2) errors in functions are easily detected by users and reported - and fizxed quite quickly and finally 3) I guess an export / ... includes quite a lot of functions, which are therefore tested as well (kind off...). > > We could even potentially leverage the existing Emacs macro system to > build a *record* method so that users could semi-automatically record > their actions allowing an interactive method of recording tests (or > submitting a re-creatable bug report).

Like the error reporting: atach the current buffer, record what was done and *the individual configuration of org / emacs* and finally email / upload it to an address, where it is automatically added to other submitted test cases, might bring us a long way closer to an very useful test base. I am actually ot aware of any other test framework, which let's "normal" users submit test cases via email / internet - I think that would be a very useful addition. > > Hope this is helpful -- Eric Most definitely, Rainer > - -- Rainer M.
