  • Why does Rusts testing tools seem so much less polished compared to its other tooling?
    3 projects | /r/rust | 12 Aug 2022
    Testing tools on the JVM stopped using reflection about twenty years ago, they all use annotations these days (e.g. https://testng.org, https://junit.org). Rust has annotations too, obviously.
  • Reassessing TestNG vs. Junit
    6 projects | /r/java | 20 Sep 2021
    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.
