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.

# Conduit: the Realworld project

We leveraged both the **React frontend** and the **Node.js backend** of the RealWorld project.  The project is called Conduit, and is a clone of Medium, the popular blogging platform.



- We shared some constants between the source code and the tests code
- We delayed every backend operation to simulate E2E testing bottlenecks
- We added the option to wipe out the entire DB





Let's learn about the Conduit app, which we will use throughout the course for testing.
