You should backslash-escape the quotes ("foo \'bar\' baz"), however, in this case, it would make sense to use regex's with 'grep' to check that you got the expected error message rather than reproducing the message literally here in the script.

It's setting up the aliases but never actually invoking them. I would have expected the next line to actually run a command ("git nested-internal-1") and the line after that to check that you got the expected output (whatever "git status" would emit). Output from "git status" isn't necessarily the easiest to test, though, so perhaps pick a different Git command for testing (something for which the result can be very easily checked -- maybe "git rm" or such). > +test_expect_success 'nested aliases - mixed execution' ' > + git config alias.nested-external-1 "!git nested-external-2" && > + git config alias.nested-external-2 status > +' Same observation. > +test_expect_success 'looping aliases - internal execution' ' > + git config alias.loop-internal-1 loop-internal-2 && > + git config alias.loop-internal-2 loop-internal-3 && > + git config alias.loop-internal-3 loop-internal-2 && > + test_must_fail git loop-internal-1 2>output && > + grep -q "fatal: alias loop detected: expansion of '"'"'loop-internal-1'"'"' does not terminate" output && Don't bother using -q with 'grep'. Output is hidden already by the test framework in normal mode, and not hidden when running in verbose mode. And, the output of 'grep' might be helpful when debugging the test if something goes wrong. As noted above, you can use regex to match the expected error rather than exactly duplicating the text of the message. Finally, use 'test_i18ngrep' instead of 'grep' in order to play nice with localization. > + rm output Tests don't normally bother cleaning up their output files like this since such output can be helpful when debugging the test if something goes wrong.

That will probably be the easiest thing to do. I commented it out for now, added a short information about that to the code itself and a longer explanation to the commit message. > >> As a last thing, is there any better way to use single quotes >> than to write '"'"'?

Backslash-escaping didn't work, that resulted in some parsing error. I'm using i18ngrep now to search for the part of a message, which eliminates the need for quotes completely. > > More below. > >> diff --git a/t/t0014-alias.sh b/t/t0014-alias.sh >> @@ -0,0 +1,38 @@ >> +#!/bin/sh >> + >> +test_description='git command aliasing' >> + >> +. ./test-lib.sh >> + >> +test_expect_success 'setup environment' ' >> + git init >> +' > > "git init" is invoked automatically by the test framework, so no need > for this test.

Whoops, I didn't know when that went missing. I added it into a new version of this patch. Also, I decided to keep `git status`, because it seemed to be the only command which doesn't need any files to produce some checkable output. Checking the "On branch" message should be enough to confirm that the command works as intended. > >> +test_expect_success 'nested aliases - mixed execution' ' >> + git config alias.nested-external-1 "!git nested-external-2" && >> + git config alias.nested-external-2 status >> +' > > Same observation. > >> +test_expect_success 'looping aliases - internal execution' ' >> + git config alias.loop-internal-1 loop-internal-2 && >> + git config alias.loop-internal-2 loop-internal-3 && >> + git config alias.loop-internal-3 loop-internal-2 && >> + test_must_fail git loop-internal-1 2>output && >> + grep -q "fatal: alias loop detected: expansion of '"'"'loop-internal-1'"'"' does not terminate" output && > > Don't bother using -q with 'grep'.

Any pointers to what the correct procedure for this case is would be appreciated. Thanks for looking at this. Tim

That makes it easier on reviewers (who don't need to go searching through the mailing list archive to get a full picture) and reduces Junio's workload since it's usually easier for him to re-queue a series wholesale than having to slice-and-dice some replacement patches into what was already queued.

Introduce a testing suite that is dedicated to aliases. For now, check only if nested aliases work and if looping aliases are detected successfully. The looping aliases check for mixed execution is there but expected to fail because there is no check in place yet. Signed-off-by: Tim Schumacher <timschumi@gmx.de> --- Those are the tests that I've come up with. It consists of tests for nested aliases and looping aliases, both with internal calls and external calls. Unfortunately I don't have a fix for the last one yet, so I marked it as expect_failure. The problem is that the test suite is waiting a full minute until it aborts the running command (which I guess should not take that long, as it blocks the whole test suite for that span of time). Should I try to decrease the timeout or should I remove that test completely until I manage to get external calls fixed? As a last thing, is there any better way to use single quotes than to write '"'"'? It isn't that bad, but it is hard to read, especially for bash newcomers. t/t0014-alias.sh | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100755 t/t0014-alias.sh
