Overview

Catch-all adapter for parallel test runners that follow the TEST_ENV_NUMBER / PARALLEL_TEST_GROUPS env-var convention but ship no Ruby API for SimpleCov to hook. wait_for_siblings is inherited from Base as a no-op: without a runner-provided API the only synchronization available is polling the resultset cache.

  ENV.key?("TEST_ENV_NUMBER")
end

.expected_worker_count ⇒ Integer

Returns:

  • (Integer)

def expected_worker_count
  parallel_test_groups_count
end

.first_worker? ⇒ Boolean

parallel_tests sets the first worker's TEST_ENV_NUMBER to "", and runners that number from 1 use "1". Both shapes match; any other value is a non-first worker.

Returns:

  • (Boolean)
