How to run Junit testcases from command line?

I've run my JUnit tests using maven before. Now I'm packaging all my source code into a JAR file, and want to run it using a java command. How can I do that? Note that there is no main class in my code.

You need to make sure the classpath contains

Your JAR
The JUnit JAR

You can set the class path by using the -cp flag to the java command. Then you can use junit.textui.TestRunner to run the tests.

If you're using Linux (note the use of : as the path separator between jars)

java -cp /path/to/my.jar:/path/to/junit.jar junit.textui.TestRunner com.mypackage.MyClassWithUnitTests

If you're using Windows (note the use of ; as the path separator between jars)

java -cp /path/to/my.jar;/path/to/junit.jar junit.textui.TestRunner com.mypackage.MyClassWithUnitTests

For Junit4 you can use this: java -cp /path/to/my.jar;/path/to/junit.jar org.junit.runner.JUnitCore com.mypackage.MyClassWithUnitTests
