Jupiter Engine - parallelism config for classes and methods

[ArvindJoshi-okta]

In JUnit4/failsafe, I used the following config for parallelizing classes and methods. Specifically, I want to hit the exact number of threads for classes and methods and both should run in parallel. How do I achieve this using the Jupiter engine? I tried various ways with fixed and dynamic options, where the number of threads end up as X+Y and the actual number of classes that run in parallel aren't exactly X, could be X+1 or more if there are more classes in the maven lifecycle.

I would like to see up to X classes in parallel consistently, if X threads are available and the up to Y methods in parallel if they are available.

<parallel>classesAndMethods</parallel>
<threadCountClasses>X</threadCountClasses>
<threadCountMethods>Y</threadCountMethods>

Jupiter's parallel execution implementation does not have two separate parameters for these thread counts. Why is it important that exactly X classes run in parallel?
