Refactor one of the fsck tests to use a throwaway repository. It's a pervasive pattern in t1450-fsck.sh to spend a lot of effort on the teardown of a tests so we're not leaving corrupt content for the next test. We can instead use the pattern of creating a named sub-repository, then we don't have to worry about cleaning up after ourselves, nobody will care what state the broken "hash-mismatch" repository is after this test runs. See [1] for related discussion on various "modern" test patterns that can be used to avoid verbosity and increase reliability. 1. https://lore.kernel.org/git/87y27veeyj.fsf@evledraar.gmail.com/ (local) Signed-off-by: Ævar Arnfjörð Bjarmason <redacted> --- t/t1450-fsck.sh | 35 ++++++++++++++++++----------------- 1 file changed, 18 insertions(+), 17 deletions(-)
