Looks ok.


I think you can reduce some of the boiler plate by having before/after test methods:

Path root;
Path classes;

@BeforeMethod
void testInit(Method m) {
  root = Paths.get(method.getName());
  classes = root.resolve("classes");
}

@AfterMethod
void testCleanup() {
  FileUtils.deleteFileTreeWithRetry(root);
}


I dunno if your test methods really need to declare "throws Throwable”.

Paul.
