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.

Using AssertJ for assertions


In this recipe, we will add AssertJ to your classpath (or check if it's already there) and take a look at a test that should show the concept that lies behind the AssertJ library.

Getting ready

First, let's check the differences between the different AssertJ JAR files:

  • assertj-core: This file contains the vast majority of assertions (there is rarely a need to have any additional dependencies)

  • assertj-guava: This file contains additional assertions for some of the Guava library related classes

  • assertj-neo4j: This file contains additional assertions for the Neo4j graph database related classes

  • assertj-joda-time: This file contains additional assertions for the JodaTime library related classes

  • assertj-assertions-generator-maven-plugin: This is a Maven plugin for generating AssertJ assertions

In most cases, all you need is assertj-core since it already has plenty of useful assertions.

Regardless of the fact that you are using JUnit or TestNG, you still have to add assertj...
