Getting pytest

The headquarters for pytest is https://docs.pytest.org. That’s the official documentation. But it’s distributed through PyPI (the Python Package Index) at https://pypi.python.org/pypi/pytest.

Like other Python packages distributed through PyPI, use pip to install pytest into the virtual environment you’re using for testing:

​ $ pip3 install -U virtualenv
​ $ python3 -m virtualenv venv
​ $ source venv/bin/activate
​ $ pip install pytest

If you are not familiar with virtualenv or pip, I have got you covered. Check out Appendix 1, ​Virtual Environments​ and Appendix 2, ​pip​.

What About Windows, Python 2, and venv?

The example for virtualenv and pip should work on many POSIX systems, such as Linux and macOS, and many versions of Python, including Python 2.7.9 and later.

The source venv/bin/activate line won’t work for Windows, use venvScriptsactivate.bat instead. Do this:

​ C:> pip3 install -U virtualenv
​ C:> python3 -m virtualenv venv
​ C:> venvScriptsactivate.bat
​ (venv) C:> pip install pytest

For Python 3.6 and above, you may get away with using venv instead of virtualenv, and you don’t have to install it first. It’s included in Python 3.6 and above. However, I’ve heard that some platforms still behave better with virtualenv.
