We really need a new #JUnit logo! 🤣

Proposals are welcome!

Je suis au #DevLille, et le premier talk que je voie parle de tests concis et évolutifs grâce à #JUnit 5, présentés par une contributrice du projet.

Parameterized test class support has landed in JUnit. Read all about it in this blog post by JUnit maintainer @marcphilipp: https://www.marcphilipp.de/blog/2025/06/07/stf-milestone-4-parameterized-test-classes/

If you're using #JUnit 5.13, I suggest you pay attention to discovery issues!

Run your build once with:

-Djunit.platform.discovery.issue.severity.critical=INFO

And see if your build fails. 🕵🏻‍♂️

NOTE: the default critical severity may change in 6.0.

✨ New blog post: "STF Milestone 4: Parameterized test classes"

#JUnit 5.13 introduced parameterized test classes (in addition to methods). They are a powerful testing tool that has long been missing from JUnit Jupiter. I’m super happy that I’ve finally had the chance to resolve this long-standing and highly-voted issue thanks to the @sovtechfund.

@ParameterizedClass
@ValueSource(strings = {"foo", "bar"})
class SomeTests {
@Parameter String value;

@Test
void shouldNotBeNull() {
assertNotNull(value);
}
@Test
void lengthShouldBeThree() {
assertEquals(3, value.length());
}
}

Since we've already started work on #JUnit 6, I guess it's time to change "JUnit 5 committer" in my profile to simply "JUnit committer" on this platform. 😉

Consider this #ClickBait if you dare, but don't expect me to reply. 🤣
