The bug scan found 4 broad issues in idle_test/*. Details in full reports or in numbered links below.

71 CONSIDER idle_test/mock_idle.py:48 The shared test stubs cannot express the conditions the guards under test exist for
72 CONSIDER idle_test/test_searchengine.py:279 A test class freezes text.index to a constant, leaving seven mutations of live code undetected

Fixed:
26 CONSIDER idle_test/test_autocomplete.py:241 Five tests in the suite cannot fail
73 CONSIDER idle_test/test_undo.py Four test files exit 0 even when their tests fail
