junit: impact of forkMode=“once” on test correctness

Question

I\'d like to reduce the time which our build (using ant) takes for running the tests. Currently I am using the default forkMode, which forks a new vm on each test cl

Answer 1

Looking at Stefan's blog entry about this I would venture to guess:

1. you will only get a single class loader for forkMode="once"
2. you won't have access to the Ant environment anymore
3. the GC will be performed inside the spawned GC (if forceMode="once") and this means it's NOT after each test is run.
