v5.5.4

Fixes issue 3277.

gradle test --tests "A*" --tests "B*"

All tests from A* and B* were skipped instead of being ran.

This was a regression from 5.4.x, where this used to work. This was because kotest 5.5.3 were using the wrong combinators for combining the inclusion filters.

v5.5.3

Updated JUnit version from 5.7.2 to 5.8.2

Kotest now requires the runtime version of JUnit to be at least 5.8

Note: If your build somehow manages to put both JUnit 5.7 and 5.8 onto the classpath and they load in the wrong order, you might see problems related to ClassOrderer not being found. Please make sure that only JUnit 5.8+ is loaded
