[PATCH] tests: add tests for the bash prompt functions in the completion script

[PATCH] tests: add tests for the bash prompt functions in the completion script

[SZEDER Gábor]

The tests cover the discovery of the .git directory in the __gitdir()
function in different scenarios, and the prompt itself, i.e. branch
name, detached heads, operations (rebase, merge, cherry-pick, bisect),
and status indicators (dirty, stash, untracked files; but not the
upstream status).

Perhaps it would make sense to create another file for these,
specially since there's the plan of splitting the prompt stuff to a
separate file.

I thought about that briefly but decided against it to avoid
duplicating the bash-specific checks at the beginning, but I don't
care that much either way.

Oh, I was not aware of such a plan.  What would be the benefits of
such a move, why is it necessary?  Where would you split it up?  In
particular, what would happen with __gitdir(), which is used in many
completion functions and in __git_ps1() as well?

I guess __gitdir() would be duplicated, I don't think that has been discussed.

http://thread.gmane.org/gmane.comp.version-control.git/194188

Basically splitting helps for systems that use bash-completion, and
also helps for zsh users who don't want the bash completion, but still
want __git_ps1(). I split the file myself for this reason.

Cheers.

Thanks for the pointer, those are valid reasons.  I'll wait a day or
two for feedback, then resubmit as a different test script.

Maybe a t/lib-completion.sh would take care of that.  FWIW a clean
split in the test script so it doesn't grow into something like the
current fast-import tests sounds like a good idea to me. :)

Here you go.  I put only the conditionals to run the test script under
Bash and the sourcing of test-lib.sh into t/lib-completion.sh, because
that's the common part that is required by the prompt tests, too.  So in
the end I'm not sure that t/lib-completion.sh is the right name for this
file.

This patch could probably be squashed into the first commit of
fc/completion-tests, i.e. 5c293a6b (tests: add initial bash completion
tests, 2012-04-12).

[PATCH v2 2/2] tests: add tests for the bash prompt functions in the completion script

[SZEDER Gábor]

The tests cover the discovery of the .git directory in the __gitdir()
function in different scenarios, and the prompt itself, i.e. branch
name, detached heads, operations (rebase, merge, cherry-pick, bisect),
and status indicators (dirty, stash, untracked files; but not the
upstream status).

Tests are the same as in the prvious round, but in a different test file.

If I understand correctly, this sources lib-completion immediately
instead of following the usual pattern of

	. ./test-lib.sh
	. "$TEST_DIRECTORY/lib-completion.sh"

to get the self-execing over with ASAP.  "$0" always refers to the
original shell script and not the file being sourced so this should be
safe.  Looks good.

Should be 100755, no?

Yes, of course.  Forgot to re-format-patch after amend.

There are a couple of other test libs that source test-lib.sh
themselves, similarly to the new t/lib-completion.sh.

Exactly, like the original t/t9902-completion.sh.

Yeah, I tested the tests ;) with dash as /bin/sh; works for me.

I wonder what this 'echo...;exit' is about (I do so since I saw it the
first time when Felipe submitted his patch). Shouldn't it be more like:

	skip_all='skipping bash completion tests; bash not available'
	test_done

It should, if the test library was loaded at that point, but it isn't.
BTW, I didn't write that code.

In any case, what the user sees is exactly the same, except without color.

Cheers.
