Hi friends,
Just wanted to drop this here. I was testing some agenda-related code,
and got tired of having to keep moving the dates forward on my test data
as days passed in real life, so after digging into the agenda code, I
came up with this macro that makes testing much easier:
#+BEGIN_SRC elisp
(defmacro with-org-today-date (date &rest body)
"Run BODY with the `org-today' function set to return simply DATE.
DATE should be a date-time string (both date and time must be included)."
(declare (indent defun))
`(let ((day (date-to-day ,date))
(orig (symbol-function 'org-today)))
(unwind-protect
(progn
(fset 'org-today (lambda () day))
,@body)
(fset 'org-today orig))))
#+END_SRC
You can use it like this:
#+BEGIN_SRC elisp
(with-org-today-date "2017-07-05 00:00"
(let ((org-agenda-files (list "~/test.org"))
(org-agenda-span 'day))
(org-agenda-list nil)))
#+END_SRC
Hope someone finds this useful.

You should be able to simplify the macro body to
`(cl-letf (((symbol-function 'org-today) (lambda () (date-to-day ,date))))
,@body)

Hi Kyle,
I tried that, but it didn't work, so I had to come up with this uglier
one. I couldn't figure out why, but with cl-letf, the redefined
function didn't seem to persist deeper in the tree of function calls,
only to the first level. Maybe I did something wrong, but all I know
now is that at least this works. :)
Thanks.

On my end,
(defmacro with-org-today-date (date &rest body)
`(cl-letf (((symbol-function 'org-today) (lambda () (date-to-day ,date))))
,@body))
(with-org-today-date "2017-07-05 00:00"
(let ((org-agenda-files (list "~/test.org"))
(org-agenda-span 'day))
(org-agenda-list nil)))
produces the same result as your original macro.

Thanks, maybe I was up too late to be messing with macros. :)

i duly saved this macro, didn't think to look for it, and used datefudge(1).
