From c16b388ea8bcee9acd17a555e66e61c72b973128 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 20 Jan 2025 14:25:31 -0700 Subject: test/py: Add a test which runs all unit tests Add a Python test which runs 'ut all' and then checks that the expected suites are present and all tests in each suite are run. This can help to check that nothing is missing. Update 'ut info' to ignore the 'all' suite when counting the number of suites, since that is really just a combination of all the other suites. Adjust the message for skipped tests so that appears even if no particular test was selected. This helps the new 'test_suite' test see what is going on.

This allows removal of the #ifdefs and the need to keep them in sync with the associated Makefile rules, which has actually failed, since the help does not match what commands are actually present.
