[PATCH] Interactive editor tests for commit-msg hook

[PATCH] Interactive editor tests for commit-msg hook

[Wincent Colaiuta]

Supplement the existing tests for the commit-msg hook (which all use
"git commit -m") with tests which use an interactive editor (no -m
switch) to ensure that all code paths get tested.

I didn't add similar tests for the pre-commit hook because I don't
think that's an interesting code path; we don't care about the commit
message in that case, only whether the commit is allowed to proceed or
not.

Sensible.

Hmm.  Why "export"?

I initially was going to say "this is just a style thing", but I really
want our tests to read uniformly like this:

        test_expect_success 'without hook (editor)' '

                echo more foo >>file &&
                git add file &&
                echo more foo >FAKE_MSG &&
                GIT_EDITOR="$FAKE_EDITOR" git commit

        '

 * Use single quotes around test unless there is a compelling reason not
   to;

 * The opening single quote of the test body on the same line as
   expect-success; the end quote at column 1 on a line on its own.

Notice a bug in your version?  Dq around $FAKE_EDITOR is stripped away
and it is harder to spot it because the script does not follow that
style.

Because I'd seen it in other tests (eg. t3404-rebase-interactive.sh),  
so I just copied the style. If it's not necessary though we can lose it.

Ok, fixed up version will follow in a couple of minutes.

[PATCH 7/7] Interactive editor tests for commit-msg hook

[Wincent Colaiuta]

Supplement the existing tests for the commit-msg hook (which all use
"git commit -m") with tests which use an interactive editor (no -m
switch) to ensure that all code paths get tested.

At the same time the quoting of some of the existing tests is changed
to conform to Junio's recommendations for test style (single quotes
used around the test unless there is a compelling reason not to, and
the opening quote on the same line as the test_expect and the closing
quote in column 1).
