I suppose there must be, but it depends on how you run from Ecilpse. I’m not an Eclipse user. Maybe someone can help you with that if you describe how you run from Eclipse, in Java terms. For instance do you start the jar or are you running classes directly, without building a jar from them, how do you pass arguments?
Regarding your ‘fix’ button idea. I don’t really see what that has to do with log files. It sounds like you want to generate alternative versions of wiki pages, where expected values are updated to actual values. You could take a look at the code to generate the ‘re-run suite’ that is generated when some pages in a suite fail. That gives an indication how to create a new page, from code, that can immediately be run from the wiki. But I don’t think this can be a generic feature: test failures could depend on input values to a fixture, not just direct expectations, or symbols could be used as expected values (ie the expected value is the output of some other method). It could of course work in your specific test setup and fixtures.
