Advanced Python testing with Pytest

Solving complex functional testing with Python

Topic: Software Development
Noah Gift
Alfredo Deza

The popular testing tool pytest is great for unit testing, but it can do so much more. However, learning how to use pytest for functional and integration testing requires a detailed approach lacking in most introductory training resources.

Join experts Alfredo Deza and Noah Gift to get a better grasp on solving a complex test matrix with ease, including performing highly functional tests with databases, web services, and containers. You’ll go from basic test runs that although sufficient don’t really help in the case of failure all the way to adding advanced techniques expanding on the framework—making all of these changes live and debugging as you progress.

What you'll learn-and how you can apply it

By the end of this live online course, you’ll understand:

  • Important differences between functional, integration, and unit testing
  • How to implement complex setups for functional testing like temporary databases
  • How to enhance error reporting with custom pytest hooks
  • How to connect containerized testing with fixtures
  • How to use tox and pytest to build a large test matrix

And you’ll be able to:

  • Manage a testing matrix, from smallest to largest
  • Create, configure, and tear down complicated functional test setups
  • Use Python to test containers and other remote services
  • Improve failure reporting, customized to specific business requirements

This training course is for you because...

  • You’re a data scientist, student, or developer already using Python, and you want to level up your testing and pytest knowledge.
  • You’re involved in testing and are looking for the best ways to tackle complex testing scenarios like containers and web services.

Prerequisites

  • A working knowledge of Python
  • A computer with the latest version of pytest installed and the course repository cloned
