Py.Test

Python test suite. The pytest framework makes it easy to write small tests, yet scales to support complex functional testing for applications and libraries.

Installation

pip install pytest               # core
pip install pytest-cache         # bytest cache plugin
pip install pytest-cov           # generate code coverage report
pip install pytest-pep8          # check python code style

Basics

Write Tests

Put your tests in a directory named tests. Each name of files containing tests should starts with test_. Each test function should start with test_.
