Arch test is junit 4?

yes

If you're using

useJUnitPlatform()

in your build, but want JUnit platform to run junit4 tests, you need to ensure you have the junit vintage runner on the classpath. I'll send a link shortly

thanks

https://junit.org/junit5/docs/current/user-guide/#running-tests-build-gradle-engines-configure Second code example, and paragraph above talks about running JUnit 4 tests. Basically, add the junit-vintage-engine as described there, and Junit Platform should run both sets of tests.

jupeee! works
