Run all tests in Junit 4

Question

I want to be able to run all tests in a project programmatically. I know Eclipse has a \"Run as JUnit test\" configuration which somehow grabs all the tests in a project and run

Answer 1

Of the top of my head using Spring:

• Implement a TypeFilter that matches classes with methods annotated with @Test (don't forget to consider the superclasses)
• Invoke classpath scanning on your top-most test package
• Invoke the JUnitRunner with the scan results
