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.

Class Method Details

.combine(*results) ⇒ Hash

Combine process explanation => ResultsCombiner: hand every result to one accumulator. ==> CoverageAccumulator::MergedFile: hold one file's merged coverage. ===> LinesCombiner: combine lines results. ===> BranchesCombiner: combine branches results. ===> MethodsCombiner: combine methods results.

Callers that read their results one at a time (ResultMerger, to keep a big CI run's resultsets out of memory all at once) should drive a CoverageAccumulator directly instead of collecting the results to pass here.

Returns:

  • (Hash)
