Supported unittest assert methods:

• assertEqual
• assertNotEqual
• assertEquals
• assertDictEqual
• assertSetEqual
• assertTupleEqual
• assertListEqual
• assertSequenceEqual
• assertIs
• assertIsNot
• assertIsNone

Mocks assert methods:

• assert_called_once
• assert_called_once_with
• assert_not_called
• assert_called_with
• assert_has_calls

Currently, diff colorization output can vary, especially for more complex assert comparisons such as large, nested dicts. This is a side effect of the way dehaze calculates diffs by utilizing difflib and passing in stringified expected/actual values.

Development

Refer to Makefile for commands to test, autoformat, lint, typecheck, etc.

pip install -r requirements.txt       # minimum to run code
pip install -r requirements-dev.txt   # for autoformat, lint, type checking, debugging
pip install -r requirements-test.txt  # for running tests

Testing

# simply run tests
make test

# run tests with all supported python versions
make test-all
