Those are found in the tests/golden/ directory.
This test suite contains four top-level directories corresponding to four categories of tests, namely:
good/: these adhere to the POSIX standard, and should be accepted.bad/: these do not adhere to the standard, and should be rejected.unspecified/: cases where the standard says that the behavior is unspecifiedunknown/: cases where we could not figure out whether there are good, bad, or unspecified.
A test is a directory whose name finishes in .t. Such tests can be nested as
subdirectories of the four top-level ones at an arbitrary depth. Test
directories contain an input file input.sh. Good tests contain an additional
expectations file expected.json. Finally, tests may contain an open file
that specifies that the test in question has an open issue attached to it; such
tests are expected to fail.
Tests are structured by the section of the policy concerned, whenever possible. Please add a comment at the beginning of the test file, explaining what is being tested.
