How to break into debugger within a jUnit test cas

Question

I'm debugging a unit test in a large java project. I need to run 'ant test ...' to launch the test suite. So it's difficult for me to launch it from the IDE. Is it possible to call some function like Debugger.Break() in C# to break into the debugger if it's attached to any debugger?

Answer 1

If I am understanding your question correctly, you can use java's remote debugging by setting these 2 jvm parameters:

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=1044

And for debugging your ant task you can add the these parameters in your ant <java> task. For details you may follow java debug options in ant link.
