|[buckminster-dev] Re: Executing JUnit tests with headless Buckminster|
Best regards, Dann
Over the weekend I have experimented with running JUnit tests from headless Buckminster. I wrote a new headless command that launches tests from within the workspace in a separate VM. On the positive side, everything went fine and I was able to run tests defined in the workspace. On the negative side, I basically duplicated code from JDT's JUnit plug-in.
I'd love to reuse jdt.junit code, but unfortunately the JDT team has chosen *not* to separate the JUnit launching part from the UI part. Installing a whole bunch of UI stuff into headless Buckminster didn't seem like a good idea to me. So I went for copying a stripped down version of the JUnit execution code because the actual amount of code needed was relatively small.
Then I started looking into PDE JUnit testing, and that's where things are beginning to get ugly. Again, PDE's JUnit launching code is happily coexisting with UI code in the same plug-in. Launching an equinox runtime to execute JUnit plug-in tests is not exactly a walk in the park, so I doubt that code duplication is a viable approach here.
Ultimately, I would want to be able to read JUnit launch configurations from a file and execute them in Buckminster headless. This way, the user can specify VM args, equinox configurations, etc. for his tests. But this requires Buckminster to understand all parameters of JDT's and PDE's launch configurations.
In my eyes, the only reasonable way for a solid JUnit integration in headless Buckminster would be to reuse JDT's and PDE's JUnit launching code. This would require the JDT and PDE teams to separate their core code from their UI code and put it into separate bundles. I guess there's no way this is going to happen if *I* file a bugzilla, even if I attach a patch.
Thomas, what's your view on this? Do you see alternatives? Would you be able to persuade the JDT/PDE teams to do such a refactoring?
