pytest Quick Start Guide

Converting asserts with unitest2pytest

Once you have changed the test runner to pytest, you can take advantage of writing plain assert statements instead of self.assert* methods.

Converting all the method calls is boring and error-prone, that's why the unittest2pytest tool exists. It converts all self.assert* method calls to plain asserts, and also converts self.assertRaises calls to the appropriate pytest idiom.

Install it using pip:

λ pip install unittest2pytest

Once installed, you can now execute it on the files you want:
