Module: Glib::Test::ParallelCoverage

Extended by:

ActiveSupport::Concern

Defined in:

lib/glib/test/parallel_coverage.rb

Overview

ParallelCoverage configures Rails parallel testing to work properly with SimpleCov.

Without this configuration, SimpleCov reports inaccurate coverage (often very low, like 1-2%) when running tests with parallelization enabled, because it only captures data from one worker instead of merging results from all parallel workers.

Usage:

class ActiveSupport::TestCase
  include Glib::Test::ParallelCoverage
end

This will:

• Enable parallel test execution using all available processors

• Configure SimpleCov to track each worker separately

• Automatically merge coverage results from all workers
