Re: [Jython-dev] Run java test in IDE

[Jeff A. <ja...@fa...>]

Hi Isaiah,

I'm using Eclipse (and mostly on Windows), so this is likely to be 
different for you, however ...

Jython-the-program has always run very badly for me under the IDE: I 
just don't seem to be able to give it the environment it needs, and 
console I/O is a basket case. I always run Jython at the command prompt. 
If I need to single-step the code, I use remote debugging.

JUnit tests, on the other hand, work brilliantly under the IDE, 
including debugging. The only niggle I commonly encounter is that to 
raise a PyException I have to create an instance of the interpreter 
(static PythonInterpreter interp = new PythonInterpreter(); ) in my test 
fixture.

Finding the built-in types uninitialised is, for me, a symptom of having 
the build path in the wrong order. In some circumstances (debugging 
exposed classes, and between "clean" and "build", I think) one has to 
have the ~/src directory first, but this then means that when loading 
classes, the JVM finds the unexposed version of the class instead of the 
exposed one -- not that ~/src contains any classes, but I think Eclipse 
helpfully finds them. So mostly I have the ~/exposed directory first, 
and ensure "expose" has run on the latest source.

Now if you're actually testing the exposer ... that seems likely to add 
a whole new layer of confusion, but I hope some of the above helps.
