Description

Added filters so that autogenerated by Kotlin methods of data classes are not tested by plugin/cli/contestEstimator

Fixes #1191

Type of Change

  • Minor bug fix (non-breaking small changes)

How Has This Been Tested?

Manual Scenario

Tested the behavior in plugin -- autogenerated methods are not added to memberlist (unless they are overridden).
In cli tests for autogenerated methods are also not generated.

Checklist (remove irrelevant options):

  • The change followed the style guidelines of the UTBot project
  • Self-review of the code is passed
  • The change contains enough commentaries, particularly in hard-to-understand areas
  • New documentation is provided or existed one is altered
  • No new warnings
  • New tests have been added
  • All tests pass locally with my changes

Is it possible here? isEnum and isData are just properties...

Just a simple one, like

when {
    method.classId.isEnum -> ...
    method.classId.isData -> ...
    else -> ...
}

It is JVM-synthetic and needed when copy is called with default parameters, after last commit it is not needed here.

What about overridden methods in data classes for CLI?

Am I right that CLI will not generate test methods for overridden "synthetic" methods in data classes (equals, for example)?

Yes, and it seems difficult (or impossible) to check if the method is not compiler-generated but overridden by user (but if you know the way, I would appreciate hearing it). Added a comment to code about this.
