Description
Should only be tackled after #843 and #844 (as they'll make it much much easier I reckon).
I want us to be able to run without taking line coverage measurements. Right now Line coverage is always measured and it's the default.
So for now I want us to be able to run simplecov with only branch coverage enabled, but later on also only method and oneshot lines coverage.
Not sure how we'd deactivate line coverage yet, my current proposal would be something:
use_coverage :branch
# later on extendable to also take multiples
use_coverage :branch, :methods
As line coverage is deeply ingrained into simplecov trying this might crash in unexpected places and I believe it's better to fix them in small PRs (if possible) and not one big PR.
I believe our best bet is more general data structures that can work for every coverage criterion like the coverage method introduced to FileList and SourceFile which then maps coverage criterion to an instance of CoverageStatistics.
