Class: SimpleCov::CoverageStatistics

Relationships & Source Files
Inherits: Object
Defined in: lib/simplecov/coverage_statistics.rb

Overview

Holds the individual data of a coverage result.

This is uniform across coverage criteria as they all have:

  • total - how many things to cover there are (total relevant loc/branches)

  • covered - how many of the coverables are hit

  • missed - how many of the coverables are missed

  • percent - percentage as covered/missed

  • strength - average hits per/coverable (will not exist for one shot lines format)
