Robert Muir updated LUCENE-1844:
--------------------------------
Attachment: LUCENE-1844_norms.patch
i sorted all tests on reverse time, and looked at a few of the slowest tests,
especially ones > 10 seconds.
* TestQualityRun is > 10 seconds, fixed to be < 1 second in LUCENE-2268 (will
commit later)
* TestNorms is > 10 seconds, yet if it uses RAMDirectory instead of
FSDirectory, its < 1 second.
attached is a patch, is there any reason TestNorms needs FSDirectory for good
testing?!
> Speed up junit tests

> As Lucene grows, so does the number of JUnit tests. This is obviously a good
> thing, but it comes with longer and longer test times. Now that we also run
> back compat tests in a standard test run, this problem is essentially doubled.
> There are some ways this may get better, including running parallel tests.
> You will need the hardware to fully take advantage, but it should be a nice
> gain. There is already an issue for this, and Junit 4.6, 4.7 have the
> beginnings of something we might be able to count on soon. 4.6 was buggy, and
> 4.7 still doesn't come with nice ant integration. Parallel tests will come
> though.
> Beyond parallel testing, I think we also need to concentrate on keeping our
> tests lean. We don't want to sacrifice coverage or quality, but I'm sure
> there is plenty of fat to skim.
> I've started making a list of some of the longer tests - I think with some
> work we can make our tests much faster - and then with parallelization, I
> think we could see some really great gains.
