When running tests with --enable-coverage, gcov writes diagnostic messages to stderr which get mixed with program output due to stderr=subprocess.STDOUT in run_and_get_output(). This causes test failures as the TAP parser encounters unexpected output. Add hide_stderr=True to most run_and_get_output() calls to discard coverage diagnostics while preserving the actual program output needed for test validation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
