Re: [Junit-devel] Big memory demanding tests problem

[David S. <sa...@mi...>]

Jonathan,

I have not used Spring directly, so learning a bit more will probably
help me in the future.  Are you directly shutting down the application
contexts, or should that happen automatically at garbage collection?
If you create a lot of application contexts in a loop, do you see
similar results to what you saw for JUnit?

JUnit 3 did indeed create all of the instance fields for all test
objects at once, but this is intentionally fixed in JUnit 4.  Can you
give me an example of how your tests look that would help me figure
out whether JUnit can do something more to help your situation?
