However, $command is not necessarily a git command; it could be a test helper function. In an effort to stop using test_must_fail with non-git commands, instead of invoking `test_must_fail $command`, run `OVERWRITING_FAIL=test_must_fail $command` instead in test_submodule_switch_common(). In the case where $command is a git command, test_submodule_switch_common() is called by one of test_submodule_switch() or test_submodule_forced_switch(). In those two functions, pass $command like this: test_submodule_switch_common "eval \$OVERWRITING_FAIL git $command" When $command is a helper function, the parent function calling test_submodule_switch_common() is test_submodule_switch_func(). For all test_submodule_switch_func() invocations, increase the granularity of the argument test helper function by prefixing the git invocation which is meant to fail with $OVERWRITING_FAIL like this: $OVERWRITING_FAIL git checkout "$1" This is useful because currently, when we run a test helper function, we just mark the whole thing as `test_must_fail`. However, it's possible that the helper function might fail earlier or later than expected due to an introduced bug. If this happens, then the test case will still report as passing but it should really be marked as failing since it didn't actually display the intended behaviour. While we're at it, some helper functions have git commands piping into another git command. Break these pipes up into two separate invocations with a file buffer so that the return code of the first command is not lost. This patch can be better viewed with `--ignore-all-space`. Signed-off-by: Denton Liu --- Changes since v1.1: * unset OVERWRITING_FAIL in more places that I missed earlier * clarify that the helper functions passed to test_submodule_switch_func() are the ones that have been modified (I'm not 100% if I understood your complaint with the text so perhaps the commit message may still need further refinement) t/lib-submodule-update.sh | 33 +++++++++++++++++++++++++-------- t/t3426-rebase-submodule.sh | 4 ++-- t/t3513-revert-submodule.sh | 20 ++++++++++++-------- t/t3906-stash-submodule.sh | 15 +++++++++------ t/t4137-apply-submodule.sh | 6 ++++-- t/t4255-am-submodule.sh | 6 ++++-- t/t5572-pull-submodule.sh | 8 ++++---- t/t6041-bisect-submodule.sh | 33 ++++++++++++++++++--------------- 8 files changed, 78 insertions(+), 47 deletions(-) diff --git a/t/lib-submodule-update.sh b/t/lib-submodule-update.sh index cd80d77707..67d9d8615a 100644 --- a/t/lib-submodule-update.sh +++ b/t/lib-submodule-update.sh @@ -304,12 +304,15 @@ test_submodule_content () { # a removed submodule. # # Removing a submodule containing a .git directory must fail even when forced -# to protect the history! +# to protect the history!
