In this chapter, we will make sure our application never regresses thanks to a handful of unit tests.
To test or not to test?
Chapter 5 is by far my favorite chapter of Mastering Spring MVC 4!
In this uplifting piece of literature, you will learn more about testing best practices: TDD, the pyramid of tests, unit tests and end-to-end tests.
We will see the difference behind mocking and stubbing and use mockito and the power of Spring’s IOC to study both options.
With spring-mvc-test we will create unit test for our web controllers as well
as our REST controllers.
Acceptance tests
Using fluentlenium, we will create simple yet powerful end-to-end tests leveraging Selenium.
I will tell you what the Page Object pattern is and how to use it with fluentlenium.
You will see how to configure Gradle to create a task for our acceptance tests and generate reports for this task.
Making it groovy
At the end of the chapter I will show you how to make your tests even better and more readable with Spock.
Then we will use Geb, a wonderful library used by the grails community to design acceptance tests on top of WebDriver.
I hope you will find the content of this chapter interesting, let me know your thoughts in the comments!
