Module: SimpleCov::Combine::ResultsCombiner

Defined in:
lib/simplecov/combine/results_combiner.rb

Overview

There might be reports from different kinds of tests, e.g. RSpec and Cucumber. We need to combine their results into unified one. This class does that. To unite the results on file basis, it leverages the combine of lines and branches inside each file within given results.
