Subject: 24.3.50; Wishlist: Make test suite user-friendlier
Date: Thu, 28 Nov 2013 22:04:26 +0200

This is a wishlist feature request: make the test suite easier to use
when some tests fail, and there's a need to investigate why and debug
them.

When you see any failures, the first thing you want to do is run only
one test that failed at a time.  But there's no way to do that, so it
seems, except by copying a (quite complex) command line from the
Makefile, while manually expanding every variable that's involved in
that.

Also, suppose one needs to run Emacs under a debugger for running a
test -- there doesn't seem to be a convenient way of doing that,
either.  Once again, start Emacs manually in GDB, then copy/paste the
command line there, and be sure to set the environment variables, like
EMACS_TEST_DIRECTORY before starting GDB.  Wait, and what if the test
forks, and you need to attach GDB to the correct Emacs process?

Another possible improvement would be for each test to automatically
save the log of its run, including any error messages, to a file.  As
things are now, one needs to do that manually as well, using shell
magic and/or 'tee', as the full log is extremely voluminous.

I wish all this could be easier, and I wish there would be a README in
that directory with instructions of how to do all that.

A good example of both the facilities and their README documentation
can be found in the Cairo distribution (look in the test/
subdirectory).

Thanks in advance.

There was a patch for some of this (eg running one test).

(It feels to me like one of things that will never get installed...)

Now you can run `make foo.log' to run the foo.el tests.

Haven't done anything about this.

Thank you.  Perhaps this should be mentioned in some README.

Yes, but you must also force the target, or remove the log file prior
the make call:

~/src/emacs> make -B -C test/automated tramp-tests.log

Yes, the issue is that the log depends only on the test source file,
not on "all of Emacs".

I mean, we could force it so that the tests are simply run every time,
but I wasn't sure if that was preferable.

(But none of the Emacs Makefiles provide any such gdb facility?)

All I can suggest here is that the Makefile define a GDB variable,
normally empty, that you can set to "gdb" on the make command-line when
you want to.

Most Emacs programs are interactive, so it's relatively easy to run
them under a debugger.  The test suite runs Emacs with a non-trivial
and quite long command line, so it's harder.

I guess it would be OK, if $GDB could be set to "gdb --args".  Thanks.

Hi,

testing and debugging are quite different things.
IMO it's not a good idea mixing these.

What about making ert offer an appropriate listing of available tests?

Thanks,

Andreas

I'm not sure I understand what you are saying.  When a test fails,
don't you want to debug Emacs to understand why and find a solution?

So yes, testing and debugging are different things, but when a test
fails, one frequently needs to debug Emacs.

I believe it is desirable to run the tests unconditionally when invoked
via make. People call "make check" for a reason.

Maybe you could even offer the test package name as target. Then one
could call "make -C test/automated tramp-tests",

There is another issue. By redirecting the output to a file, the
password prompt for tramp-tests isn't visible anymore. This is a real
regression, because these tests are intended to run for different remote
file names. Could you pipe the test output through tee or something like
this? I don't know how portable this would be, 'tho.

Best regards, Michael.

It should be portable for every platform that supports running the
test suite, since that requires a shell that can handle this.

Sure. But if there is a platform which does not support it, this
additional pipe could be suppressed on that platform. To be decided
during configure.

That depends. IIUC it's about making it more user friendly.
Perspective of users is different from core developers.

So if, say 10 from 100 tests fail, it doesn't mean to start a debug.
Maybe just taking notice and look, if it matters for current task.

We had that matter already WRT steep learning curve.
Keeping things apart if possible is important.

Best,

Andreas

If someone just wants to take a look, they can do just that.  No one
is forcing them to say "make foo.log DEBUG=1" and run the foo test
under a debugger.  This is an optional feature, as should be clear
from reading the original bug report and this discussion.

Not sure how is this related to the issue at hand.  Maybe you should
read the whole discussion.

I suppose you are right, and this is consistent with how it used to behave.

You can already do

   make -C test/automated tramp-tests.log

I don't think removing the ".log" is worth it.

Not sure I understand. Do you want to interact, ie type a password?
I think tests that require interaction are a Bad Thing.
Are these optional tests that do not normally run?

Nope. When you cal "make check" a second time, no test runs again,
'cause the log files exist already.

Again, it works only when there is no log file. The second time you
call it, nothing happens:

~/src/emacs> make -C test/automated tramp-tests.log
make: Entering directory `/usr/local/src/emacs/test/automated'
make: `tramp-tests.log' is up to date.
make: Leaving directory `/usr/local/src/emacs/test/automated'

> I don't think removing the ".log" is worth it.

If you want to rerun a test, you must remove the log file
manually. Inconvenient.

Nope. See the commentary section of tramp-test.el. Try

~/src/emacs> env REMOTE_TEMPORARY_FILE_DIRECTORY=/sudo::/tmp make -C test/automated tramp-tests.log

It will ask you for the sudo password, but you don't see the prompt.

Forget this. I haven't seen your latest change. Thanks!

Best regards, Michael.

OK, now you can do `make tramp-tests' to always run the tests.

So, you do want to run interactive tests.
Is it not more natural to run such tests from an interactive Emacs,
with M-x ert?
We could add the "tee" thing, I suppose.

I changed it so that `make tramp-tests': i) always runs the tests, and
ii) does no logging at all (ie, writes to stdout).

Whereas `make tramp-tests.log' writes to the .log file, only if that is
out of date.

I think that makes sense?

Almost anything is possible of course, but I don't want to add too many
different options for running things, in case it all gets too confusing.

I added $GDB at what seems like the right place.

I think this issue is done now.

That works perfectly, thanks a lot!

Best regards, Michael.
