For testing Elasticsearch, have you ever thought of doing two runs of the junit4 plugin? One to grab the fast unit tests first and one to grab the integration tests? I know most of the tests are integration tests but you might be able to squeeze some speed out of the process by parallelizing the unit tests. Maybe some of the integration tests can be parallelized too? Nik -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hey Nikolas, You can run the tests in parallel by specifying -Dtests.jvms=${number of tests to run concurrently} The default has been 1 for a very long time but Simon recently changed it so that it now picks a number that depends on your number of CPUs. For instance I have 8 CPUs here and by default it would start 4 JVMs. Moreover, since the beginning of the week, some (enough so that the speedup is noticeable) of our integration tests are faster since instead of indexing documents on every test, they are only indexed at the beginning of the test suite. You might also be interested in running with -Dtests.slow=true which is supposed to only run the fast tests. It can be helpful when iterating on a feature to get a sense of whether a change broke something. (The default is false.)

Cool. Thanks!
