Overview

No-op defaults for a parallel-test-runner adapter: behave like a single-process run. Real adapters subclass and override what they need. The contract methods are class methods; adapters are never instantiated.

Class Method Details

.active? ⇒ boolish

Should this adapter be selected for the current process? The first registered adapter whose active? returns truthy wins.

Returns:

  • (boolish)

def active?
  false
end

.expected_worker_count ⇒ Integer

How many parallel workers participate in this run. Defaults to 1.

Returns:

  • (Integer)

def expected_worker_count
  1
end

.first_worker? ⇒ Boolean

Should THIS worker do the final-result work (wait for siblings, merge resultsets, run threshold checks, format the report)? Defaults to true for the single-process case.

Returns:

  • (Boolean)

def first_worker?
  true
end

.native_wait? ⇒ boolish

Does wait_for_siblings block until every sibling process has exited? When true, a settled resultset count below expected_worker_count is accepted as final.

Returns:

  • (boolish)

def native_wait?
  false
end

.wait_for_siblings ⇒ void

This method returns an undefined value.

Optional: block until sibling workers have finished writing their resultsets. The no-op default leaves synchronization to SimpleCov's resultset polling fallback.
