Improve confidence in your code with tests. I'll show you how to use unit, integration, system, and acceptance tests to help you write better code and reduce regression bugs.
This course has a strong focus on web application and REST API testing using Python. We'll work with existing projects and add tests to them using the Python unittest library.
Throughout the course we'll cover mocking and patching of third party dependencies, as well as using Postman for API testing and collaboration.
To write acceptance tests we'll use Behaviour Driven Development and Selenium WebDriver to automate user interactions with a website.
So whether you are an advanced developer looking to get into testing, or a manual tester looking to get into automation, this course will help you understand all the different kinds of tests and how to write them.
Write unit tests using the unittest library
Learn about unit, integration, system, and acceptance testing
Write complete system tests using Python and tools like Postman
Browser-based acceptance testing using Behave and Selenium WebDriver

Probably the absolute best class I've ever found on the subject. Sticks with the stock 'unittest'; great explanations of when, why, and how to break up different kinds of tests; and heavy focus on mocking instead of just a gloss over. Excellent teaching. I learned a heck of a lot on this one.

Automated testing is a super power! This is by far the best "I didn't knew this existed" moment in my life.

Clear, well done and precise, could have had more lectures and hours on Selenium, but other than that, it is an excellent course.
