This chapter shows how to test your application—how to capture and automate the testing of use cases, how to unit test your APIs before they are integrated with other components, and how to integrate all of the units. We will introduce you to Behavior-Driven Development (BDD) and show how it can become the starting point of your application development. We will also demonstrate how JUnit framework can be used for unit testing. Sometimes, during unit testing, we would have to stub dependencies with some dummy data, and this can be done by mocking the dependencies. We will show you how to do this using a mocking library. We will also show you how to write fixtures to populate test data and then how you can test the behavior of your application by integrating different APIs and testing them together. We will cover the following recipes:
- Behavioral testing using Cucumber...
