How to Debug JUnit tests similar to a regular Java program within Eclipse

Question

In eclipse, if I run a Java program in debug mode with no breakpoints, and if the JVM hits a NullPointerException, Eclipse will kindly highlight the offending line of code, and show the local variables, etc. Execution is paused. I can evaluate code using the Display tab, and so on.

But, if I run a JUnit test in debug mode, and the jvm hits a NullPointerException, the jvm does not pause, and I don't have a chance to see the local variables.

Is it possible to run JUnit tests so that the JVM will pause automatically when I hit a NullPointerException, without using breakpoints?

Edit: Using JUnit 4 & Juno

Answer 1

1. Open the Junit test case or Junit Test Suite you want to run.
2. Place your Break Point.
3. Right Click on the File and click on Debug As > Junit Test.
