Overview

Builds the CoverageStatistics triple for a SourceFile regardless of which criteria were enabled during the run: disabled or empty criteria collapse to 0/0/0 so downstream consumers don't have to special-case enable-state.

#initialize(source_file) ⇒ Statistics

Returns a new instance of Statistics.

Parameters:

def initialize(source_file)
  @source_file = source_file
end

Instance Method Details

#branch_statistics ⇒ Hash[criterion, CoverageStatistics]

Files added via track_files but never loaded have no branch or method data, and report 0% instead of the empty-set default of 100% (#902). A file with missed entries and none covered already computes to 0%, so only a file that really has covered entries keeps its computed percentage.

Returns:
