Allow passing multiple test patterns separated by commas, where each pattern can use glob wildcards (* and ?). Prefix a pattern with ! to exclude matching tests. For example: make test TEST="net-*,!net-tap" make test TEST="net-*,virtiofs-*" Each comma-separated element is parsed as a glob::Pattern. Tests are included if they match any include pattern and no exclude pattern. Only-exclusion patterns (no includes) are rejected with a hint to use e.g. "*,!pattern". Also reject glob-special and comma characters in test case names to avoid ambiguity with the selection syntax. Assisted-by: OpenCode:claude-opus-4.6 Signed-off-by: Matej Hrica <mhrica@redhat.com>
