Non public classes scmMutationCoverage possible issues

[Jakub W]

Hello,

I found info in the documentantion (https://pitest.org/quickstart/maven/) about some issues with scmMutationCoverage goal:

This goal does not currently guarantee to analyse changes made to non public classes that are not inner classes.

My questions are:
1. What kind of issues can I encounter?
2. How often this kind of issues could occur?
3. Are there many issues with simple package-private classes?

Thanks in advance for your answers :)

The plugin needs to map between source file paths and affected classes. The java compiler only enforces a naming convention for public classes, so if you have non public classes defined in a modified source file they may not be included for analysis. How often this is a problem will depend on the style of your code.

This issue is does not occur with the arcmutate git plugin, which calculates mappings by a more robust method.
