Attributes

coverage[R]

The array of coverage data received from the Coverage.result

filename[R]

Returns all covered lines as SimpleCov::SourceFile::Line

  @covered_lines ||= lines.select(&:covered?)
end
covered_percent() click to toggle source

The coverage for this file in percent. 0 if the file has no relevant lines

# File lib/simplecov/source_file.rb, line 125

def line(number)
  lines[number - 1]
end
lines() click to toggle source

Returns all source lines for this file as instances of SimpleCov::SourceFile::Line, and thus including coverage data. Aliased as :source_lines

end
never_lines() click to toggle source

Returns all lines that are not relevant for coverage as SimpleCov::SourceFile::Line instances

end
process_skipped_lines(lines) click to toggle source

Will go through all source files and mark lines that are wrapped within # :nocov: comment blocks as skipped.
