Re: [jdt-ui-dev] JUnit extension problem

[Philipp.Bouillon@xxxxxxxxxxx]

Thanks for the response.
Since I have to do some dynamic analysis of the tests, I am again at a
point where I will have to think hard about the best way of doing
things...
The problem is that I'd like to get the value of a variable at any
point during the execution of the test. I thought, I could use the
eclipse debugging functionality to step through each line of the test
object. Since you just told me that this is impossible, I will have to
look for a different way...
Well... Thanks again,

Philipp
