How To Install python-pytest-expect on Ubuntu 18.04
Introduction
In this tutorial we learn how to install python-pytest-expect on Ubuntu 18.04.
What is python-pytest-expect
python-pytest-expect is:
A py.test plugin that stores test expectations by saving the set of failing tests, allowing them to be marked as xfail when running them in future. The tests expectations are stored such that they can be distributed alongside the tests. However, note that test expectations can only be reliably shared between Python 2 and Python 3 if they only use ASCII characters in their node ids: this likely isn’t a limitation if tests are using the normal Python format, as Python 2 only allows ASCII characters in identifiers.
