ABOUT THIS COURSE
This course aims to teach you how to write better Rails applications by applying good testing practices. You’ll learn about the reasoning behind testing and the process of applying good testing practices.
In the first half of the course, you’ll learn about the testing mindset and understand its importance. Next, you’ll learn to turn business requirements into user stories. These user stories will become the basis of the code and tests you’ll write.
Once you understand the reasoning and process, you’ll proceed to write the actual tests. You’ll test what is most important to the end user first. So, the first set of tests you’ll learn to write will be feature tests. Finally, you’ll learn to write request tests and unit tests ensuring end-to-end coverage of our application.
