@graemerocher it looks like an issue for Micronaut Test, not the Gradle plugin?

I would like to assist with this issue. What is the desired approach here:

1. Update the kotest module in-place, causing breaking changes and no longer supporting Kotest verrsion before 5.x
2. Create a new module for Kotest 5.x+

a new module for kotest 5.x

I have made a PR here #531
