+Subject: [PATCH] fail2ban: use putao.unittest.TestRunner for ptest output
+
+Switch the test runner from unittest's default TextTestRunner to
+putao.unittest.TestRunner (provided by unittest-automake-output) so
+that results are reported in Automake-compatible PASS/FAIL format.
+This enables ptest-runner to correctly parse and summarize individual
+test results.
+
+Upstream-Status: Pending
