test-lib: Infrastructure to test and check for prerequisites
Some tests can be run only if a particular prerequisite is available. For example, some tests require that an UTF-8 locale is available. Here we introduce functions that are used in this way: 1. Insert code that checks whether the prerequisite is available. If it is, call test_set_prereq with an arbitrary tag name that subsequently can be used to check for the prerequisite: case $LANG in *.utf-8) test_set_prereq UTF8 ;; esac 2. In the calls to test_expect_success pass the tag name: test_expect_success UTF8 '...description...' '...tests...' 3. There is an auxiliary predicate that can be used anywhere to test for a prerequisite explicitly: if test_have_prereq UTF8 then ...code to be skipped if prerequisite is not available... fi Signed-off-by: Johannes Sixt <j6t@kdbg.org>
