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

We’ve already seen how the little steps we take add up. This is the process we’ll continue. 

Mastering this process will improve one’s programming life. It takes some time to sink in, but it’s worth it in the long run.

# Setting up the test
Recall that our second step was `"I click on the registration link"`.

So, what does it mean to click on the registration link? We obviously need to have the link somewhere on the homepage because that’s where our user is when they try to click it. For this test to pass, it’s enough to find the link and click on it.

Here's how that might look:

Let’s implement and run the second feature test.
