How to run JUnit test cases from the command line

Question

I would like to run JUnit test cases from the command line. How can I do this?

Answer 1

If your project is Maven-based you can run all test-methods from test-class CustomTest which belongs to module 'my-module' using next command:

mvn clean test -pl :my-module -Dtest=CustomTest

Or run only 1 test-method myMethod from test-class CustomTest using next command:

mvn clean test -pl :my-module -Dtest=CustomTest#myMethod

For this ability you need Maven Surefire Plugin v.2.7.3+ and Junit 4. More details is here: http://maven.apache.org/surefire/maven-surefire-plugin/examples/single-test.html
