Bug 11689 NPE creating a test case in empty workbench
If you create a project and then a JUnit TestCase when there are no other classes in the image you will get a NullPointerException when you select the browse button on the Test Class entry. STEPS 1) Create a ConfigurableProject 2) Create a JUnit Test class. In the creation dialog select the 3rd browse button.
