Installing JUnit

Installing JUnit

2. For the purpose of this tutorial, download junit-4.8.1.zip file into C drive. Unzip the junit-<version-number>.zip file into the root of your C drive (C:\). This creates a folder called C:\\junit<version-number>. To keep the tutorial simple, go ahead and rename the C:\Junitx.x folder to C:\Junit.

3. Now you have extracted JUnit, you need to add Junit.jar to your classpath. This enables the Java compiler to resolve where and what JUnit is.

In Windows,

• Right click on "My Computer", select "Properties"
• In "System Properties" form, click on "Advanced" tab
• Click on "Environment Variable"
• Double-click CLASSPATH and then enter the new value Ex: C:\JUnit\junit.4.81.jar
• If you already have a setting in your CLASSPATH, make sure that you append the junit path by separating the new path with a semicolon.

 That's it. Now you are ready to execute your junit test cases.
