From 0d16451943ec4f17ea1503a12549531bb278788a Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Wed, 14 Dec 2011 02:22:03 -0600 Subject: [PATCH] test: errors preparing for a test are not special This script uses the following idiom to start each test in a known good state: test_expect_success 'some commands use a pager' ' rm -f paginated.out || cleanup_fail && test_terminal git log && test -e paginated.out ' where "cleanup_fail" is a function that prints an error message and errors out. That is bogus on three levels: - Cleanup commands like "rm -f" and "test_unconfig" are designed not to fail, so this logic would never trip. - If they were to malfunction anyway, it is not useful to set apart cleanup commands as a special kind of failure with a special error message. Whichever command fails, the next step is to investigate which command that was, for example by running tests with "prove -e 'sh -x'", and fix it. - Relying on left-associativity of mixed &&/|| lists makes the code somewhat cryptic. The fix is simple: drop the "|| cleanup_fail" in each test and the definition of the "cleanup_fail" function so no new callers can arise.
