Question

In the eclipse run command, there are two choices: JUnit Plug-in Test and JUnit Test.

JUnit Plug-in test is for testing Eclipse plug-ins. It runs a new instance of Eclipse. Then, it runs the tests.

JUnit test is for testing regular Java applications. It runs the tests without launching a new instance of Eclipse.
