[hibernate-dev] run a single unit test speed up?

[Sanne Grinovero]

Hi Jason,

I'm surprised. It's not instantaneous here either, but it doesn't take
minutes - provided you've built the project before and didn't change a
lot of code.

If I run such a test for the first time, possibly after having
switched branches, I'll get test results in ~20 seconds; most of this
is spent recompiling. But if I repeat the same command right away, it
will complete in ~1 second.

What do you see if you repeat the test a second time after having just run it?

Just for reference, a full build runnig all tests on H2 takes 6
minutes on my machine.

Thanks,
Sanne
