In t0000, we run several fake "sub-test" suites to verify the behavior of the test suite. But because we don't clear the parent environment completely, the sub-tests can be fooled by variables meant for the parent. For example: GIT_SKIP_TESTS=t1234 ./t0000-basic.sh fails when a sub-test expects its fake t1234 to actually run. This particular pattern is unlikely in practice; we're running a single script, and there is no t1234 in the real test suite anyway (not yet, at least). A more real-world example is: GIT_SKIP_TESTS=t[^0]* make test to run only the t0* tests. The fix is conceptually simple: we should clear the GIT_SKIP_TESTS variable when running the sub-tests, because its contents (if any) will be meant for the main test suite. This is easy to do centrally in our sub-test helper. But there's a catch: some of our tests do set GIT_SKIP_TESTS intentionally to test the feature. We need to allow them to continue to set it, but clear it for all the other tests. And the sub-test helper can't tell if the GIT_SKIP_TESTS it sees is from a test or not. We can handle this by adding a new option to the helper to let callers specify the skip list. I considered adding a more general "--eval" option to let callers set up the env for the sub-test however they like. That would cover this case and possible future ones. But the quoting gets awkward for the callers (since we're now 2 layers deep in evals!), so I went with the simpler more specific solution. Signed-off-by: Jeff King <peff@peff.net> --- For reference, the eval solution would look something like this in the callers: diff --git a/t/t0000-basic.sh b/t/t0000-basic.sh index f68c27d864..bf60c8fdc8 100755 --- a/t/t0000-basic.sh +++ b/t/t0000-basic.sh @@ -361,7 +361,10 @@ test_expect_success 'GIT_SKIP_TESTS several tests' ' ( run_sub_test_lib_test git-skip-tests-several \ "GIT_SKIP_TESTS several tests" \ - --skip="git.2 git.5" <<-\EOF && + --eval=" + GIT_SKIP_TESTS=\"git.2 git.5\" + export GIT_SKIP_TESTS + " <<-\EOF && for i in 1 2 3 4 5 6 do test_expect_success "passing test #$i" "true" t/t0000-basic.sh | 39 +++++++++++++++++++++++++++++---------- 1 file changed, 29 insertions(+), 10 deletions(-)
