This course will provide you with important information, principles, and experience-based advice, to enter the world of testing methodologies. 

Here, you will learn the best practices to follow to write useful and lasting tests, how to test different user flows without a working back-end, how to write effective end-to-end tests (E2E), and how to integrate tests into development and Continuous Integration pipelines.

At the end of the course, you will be able to apply the fundamental principles of the test methodologies to understand what and how to test effectively.
