Subject [jira] Commented: (LUCENE-2598) allow tests to use different Directory impls
Date Thu, 12 Aug 2010 21:10:18 GMT

Robert Muir commented on LUCENE-2598:
-------------------------------------

Committed revision 984968 to trunk. I'll backport to 3x and then look at making MockDirectoryWrapper
from MockRAM so we can support other directories in tests.

> Now that all tests use MockRAMDirectory instead of RAMDirectory, they are all picky like
windows and force our tests to
> close readers etc before closing the directory.
> I think we should do the following:
> # change new MockRAMDIrectory() in tests to .newDirectory(random)
> # LuceneTestCase[J4] tracks if all dirs are closed at tearDown and also cleans up temp
dirs like solr.
> # factor out the Mockish stuff from MockRAMDirectory into MockDirectoryWrapper
> # allow a -Dtests.directoryImpl or simpler to specify the default Directory to use for
tests: default being "random"
> i think theres a chance we might find some bugs that havent yet surfaced because they
are easier to trigger with FSDir
> Furthermore, this would be beneficial to Directory-implementors as they could run the
entire testsuite against their Directory impl, just like codec-implementors can do now.
