    Project mention: Testing integration of multiple images? | | 2021-09-19

    TestContainers looks Java specific... or are you talking about something else?

  • GitHub repo OpenJ9

    Project mention: IBM Semeru Runtimes (Eclipse OpenJ9 JVM) | | 2021-08-04

    On another note, I'm still not sure if there is a viable way to microbench code running on OpenJ9. It seems that there is still no official support from JMH, at least I'm getting warnings such as "This VM is not supported by JMH. The produced benchmark data can be completely wrong". Apparently it should work, however, my results for runs on OpenJ9 show (by a large margin) much higher variance compared to Hotspot which doesn't exactly inspire confidence.

  • GitHub repo nd4j

    Project mention: NumPy equivalent for Java? | | 2021-11-04


  • GitHub repo TestNG

    TestNG testing framework

    Project mention: Reassessing TestNG vs. Junit | | 2021-09-20

    Recently though we've run across a few issues with the asserts in TestNG. In 7.3.0, some changes broke assertSame/assertNotSame that also broke some of our tests. This was partially fixed in 7.4.0, but some overloads of assertEquals were still broken. This is fixed, but I don't think the fix has been delivered in a release yet. Further investigation revealed that at least one overload of assertNotEquals has been broken, apparently since 6.9.5 or even earlier.
