You need to add JUnit
library to the classpath of your project. There are several choices to achieve it depending on your development setup.
-
Command line: In the case of command-line invocations, you will have to add
junit.jar
to the classpath of your application withjava -cp /path/to/junit.jar
. Take a look at the answers here. -
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.
