Hey all, The Java Lucene code uses a test randomization framework. The framework's random number methods use a new seed value each time the tests are run. Whenever there's a test failure, the seed is displayed so the conditions for the failure can be replayed. As there is no equivalent randomization framework in C#, we currently just use the .net Random class whenever a random generator is required. Crucially, we don't provide a seed or even record it. As the seeds can't be known, we have no way of reproducing test failures. While I haven't seen an intermittent failure yet, I've heard that Russell ran into them occasionally.
We can either use a hardcoded fixed seed, or we can store a random seed to show when a test fails. In any case, we should remove the initializations of Random all over the place (replacing them with LuceneTestCase.Random()). What do you all think? -Prad
