As noted in the updated t/README documentation being added here setting this new GIT_TODO_TESTS variable is usually better than GIT_SKIP_TESTS. My use-case for this is to get feedback from the CI infrastructure[1] about which tests are passing due to fixes that have trickled into git.git. With the GIT_SKIP_TESTS variable this use-case is painful, you need to do an occasional manual run without GIT_SKIP_TESTS set. It's much better to use GIT_TODO_TESTS and get a report of passing TODO tests from prove(1) at the bottom of the test output. Once those passing TODO tests have trickled down to 'master' the relevant glob (set for all of master/next/pu) can be removed. As seen in the "GIT_TODO_TESTS mixed failure" test the lack of interaction with existing tests marked as TODO by the test suite itself is intentional. There's no need to print out something saying they matched GIT_TODO_TESTS if they're already TODO tests. 1. https://public-inbox.org/git/875zwm15k2.fsf@xxxxxxxxxxxxxxxxxxx/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx> --- ci/lib-travisci.sh | 2 +- t/README | 18 +++++++++-- t/t0000-basic.sh | 81 +++++++++++++++++++++++++++++++++++++++------- t/test-lib.sh | 31 +++++++++++++++--- 4 files changed, 112 insertions(+), 20 deletions(-) diff --git a/ci/lib-travisci.sh b/ci/lib-travisci.sh index 69dff4d1ec..ad8290bfdb 100755 --- a/ci/lib-travisci.sh +++ b/ci/lib-travisci.sh @@ -121,7 +121,7 @@ osx-clang|osx-gcc) # t9810 occasionally fails on Travis CI OS X # t9816 occasionally fails with "TAP out of sequence errors" on # Travis CI OS X - export GIT_SKIP_TESTS="t9810 t9816" + export GIT_TODO_TESTS="t9810 t9816" ;; GIT_TEST_GETTEXT_POISON) export GIT_TEST_GETTEXT_POISON=YesPlease diff --git a/t/README b/t/README index c03b268813..922b4fb3bf 100644 --- a/t/README +++ b/t/README @@ -207,8 +207,19 @@ ideally be reported as bugs and fixed, or guarded by a prerequisite (see "Using test prerequisites" below).
