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.

Bulletproof Ruby on Rails Applications

The main takeaway from this course is the mindset of the test-first approach. Over time, using this approach will teach you to think a lot more about what the code does, and less about how it should do it. Good tests force you to write code that’s easy to extend and maintain. 
Generally, we test what the user can see with feature tests, and everything they can’t see with request tests. We then fine-tune behavior with unit tests.
We hope that this course has made the test-first approach less intimidating. This mindset is a skill that, like any other, takes practice. But eventually it will become second nature. 





Let's wrap up with some concluding remarks.
