Question

You need to add junit library to the classpath of your project. There are several choices to achieve it depending on your development setup.

1. Command line: In the case of command line invocations, you will have to add junit.jar to the classpath of your application with java -cp /path/to/junit.jar. Take a look at the answers here.

2. Using eclipse: Eclipse distributions are bundled with this library and this is how you can use it for your project. Right click on the eclipse project and navigate:

Properties -> Java Build Path -> Libraries -> Add Library -> JUnit -> Junit 3/4

In the scenarios where you want to use a different version of the jar, instead of clicking on Add Library above you should click on Add External Jar and locate the library on the file system.

Right-click on the eclipse project and navigate:

Properties -> Java Build Path -> Libraries -> Add Library -> JUnit -> Junit 3/4

It works on mine.

If you use maven and this piece of code is located in the main folder, try relocating it to the test folder.

you can easily search for a line like "@Test" and then use the quickfix "add junit 4 library to the build path" at this line. i think this is faster than adding junit manually to the project.

If you are using eclipse and working on a maven project, then also the above steps work.

Right-click on your root folder.

Properties -> Java Build Path -> Libraries -> Add Library -> JUnit -> Junit 3/4

Step By Step Instructions here

you need to add Junit dependency in pom.xml file, it means you need to update with latest version.

<dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
        <scope>test</scope>
    </dependency> 

Seem to Junit jar file is not in path also make sure you are using jdk1.5 or above.
