From be2bb9bb2aa12e0c5732b82a5c050fa09b83b44f Mon Sep 17 00:00:00 2001 From: Jairo Llopis Date: Thu, 30 Jul 2026 08:31:16 +0100 Subject: [PATCH] [FIX] odoo_test_xmlrunner: attribute class-level errors to the right file When setUpClass or tearDownClass fails, unittest creates an _ErrorHolder without running _XMLTestResult.startTest, so xmlrunner kept the source file of the previous test in self.filename. This made the JUnit report assign the failure to an unrelated module and left classname empty. Resolve the real test class from the _ErrorHolder description (setUpClass/tearDownClass (module.ClassName)), look up its source file and line with inspect, and patch the stored test info in addError/addFailure before the report is generated. Include a regression test that reproduces the wrong-file issue and verifies the fix.
