New submission from Stéphane Blondon <stephane.blondon at gmail.com>:
In several cases, tests use ```self.assertTrue(a in b)```. Using ```self.assertIn(a, b)``` seems to be better.
For examples:
./Lib/test/test_inspect.py:
self.assertTrue('(po, pk' in repr(sig))
./Lib/test/test_configparser.py:
self.assertTrue('that_value' in cf['Spacey Bar'])
./Lib/test/test_collections.py:
self.assertTrue(elem in c)
There are some cases where ```self.assertTrue(a not in b)``` could be replaced by ```self.assertNotIn(a, b)```
./Lib/tkinter/test/test_ttk/test_widgets.py:
self.assertTrue('.' not in value)
./Lib/test/mapping_tests.py:
self.assertTrue(not ('a' in d))
self.assertTrue('a' not in d)
$ find . -name "*.py" | xargs grep -r "assertTrue.* in "
finds 131 occurences but there are some false positives inside the output.
I can write a patch if you are interested.
