This involves the inclusion of suitable testing dependencies in your project. Open the Place Reviewer project's pom.xml file and add the following dependencies:

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.12</version>
  <scope>test</scope>
  <exclusions>
    <exclusion>
      <groupId>org.hamcrest</groupId>
      <artifactId>hamcrest-core</artifactId>
    </exclusion>
  </exclusions>
</dependency>
<dependency>
  <groupId>org.hamcrest</groupId>
  <artifactId>hamcrest-library</artifactId>
  <version>1.3</version>
  <scope>test</scope>
</dependency>

In the coming sections, we are going to learn how to write tests with jUnit and Hamcrest. JUnit is a testing framework for the Java programming language and Hamcrest is a library that provides matchers, which can be combined to create meaningful expressions of intent.
