Install from source: cd /path/to/source/pytest-needleĮxample needle pytest implementation: '''test_example.py ''' from import By import pytest. Install through pip: pip install pytest-needle It's fairly similar to needle and shares much of the same functionality,Įxcept it uses pytest-selenium for handling the webdriverĪnd implements needle as a fixture instead of having test cases inherit from needle's base test class. Pytest-needle is a pytest implementation of needle.
