From f27b484b2ef60a7f74b053ea0a4987463c3c2dcc Mon Sep 17 00:00:00 2001 From: Natanael Copa Date: Mon, 13 May 2024 08:43:49 +0200 Subject: [PATCH] Treat methodName="runTest" similar to unittest.TestCase pytest 82. relies on a feature of `unittest.TestCase` where the initialization of it with the default `methodName="runTest"` is treated specially, allowing it to insantiate even without `runTest` method actually existing. See under "Changed in Python 3.2" in unittest.TestCase docs This fixes the error with pytest 8.2: AttributeError: 'TestUtil' object has no attribute 'runTest'. Did you mean: 'subTest'?
