Module: SimpleCov::CLI::Run

Defined in:
lib/simplecov/cli/run.rb

Overview

‘simplecov run <command…>` — exec the given command with simplecov auto-loaded so a coverage report drops into the project’s coverage/ directory at the end. Useful for projects without a test_helper that already calls SimpleCov.start (e.g. plain ‘bundle exec rake test` on an unconfigured library).
