Overview of this book

This is a focused guide with lots of practical recipes with presentations of business issues and presentation of the whole test of the system. This book shows the use of Mockito's popular unit testing frameworks such as JUnit, PowerMock, TestNG, and so on. If you are a software developer with no testing experience (especially with Mockito) and you want to start using Mockito in the most efficient way then this book is for you. This book assumes that you have a good knowledge level and understanding of Java-based unit testing frameworks.

In this recipe, we will take a look at a test that uses too many Mockito mocks. In this way, the test code becomes unreadable and unmaintainable. Since your test code is your living documentation, you should always remember to put a lot of effort into refactoring it until you can read it like a book.

Getting ready

For this recipe, we will again generate a new identity for a given person. Each person has an address, and that address has a street number. Since we are performing unit testing, we will check in isolation whether NewIdentityCreator properly executes its logic. It is responsible for creating a new name, new street number, and new siblings for the current person, as shown in the following code:

class NewIdentityCreator {

  public String createNewName(Person person) {
        return person.getName() + "_new";
    }

  public int createNewStreetNumber(Person person) {
        return person.getAddress().getStreetNumber() + 5;
    }
