I was running these luke tests a bunch and found the following tests fail intermittently; pretty frequently. Once I @Ignore them I can get a consistent pass:
CommitsImplTest.testListCommits CommitsImplTest.testGetCommit_generation_notfound CommitsImplTest.testGetSegments DocumentsImplTest.testGetDocumentFIelds I did not attempt to figure out why the tests were failing, but to do that, I would: Run repeatedly until you get a failure -- save the test "seed" from this run that should be printed out in the failure message Then you should be able to reliably reproduce this failure by re-running with system property "tests.seed" set to that value. This is used to initialize the randomization that LuceneTestCase does. My best guess is that the failures may have to do with randomly using some Directory implementation or other Lucene feature that Luke doesn't properly handle? Hmm I was trying this again to see if I could get an example, and strangely these tests are no longer failing for me after several runs, when previously they failed quite often. I wonder if this is somehow related to running mvn from command line vs running in IntelliJ since previously I was doing the latter -Mike On Tue, Aug 21, 2018 at 9:01 AM Tomoko Uchida <tomoko.uchida.1...@gmail.com> wrote: > Hello, > > Could you give me some advice or comments about usage of LuceneTestCase. > > Some of our unit tests extending LuceneTestCase fail by assertion error -- > sometimes, randomly. > I suppose we use LuceneTestCase in inappropriate way, but cannot find out > how to fix it. > > Here is some information about failed tests. > > * The full test code is here: > > https://github.com/DmitryKey/luke/blob/master/src/test/java/org/apache/lucene/luke/models/commits/CommitsImplTest.java > * We run tests by `mvn test` on Mac PC or Travis CI (oracle jdk8/9/10, > openjdk 8/9/10), assertion errors occur regardless of platform or jdk > version. > * Stack trace of an assertion error is at the end of this mail. > > Any advice are appreciated.
