Overview

Default no-op implementations for a parallel-test-runner adapter. Everything not overridden falls back to behaving like a single-process run. Adapters are classes, used as singletons and never instantiated.

Direct Known Subclasses

GenericAdapter, ParallelTestsAdapter

Class Method Details

.active? ⇒ Boolean

Returns:

  • (Boolean)

# File 'lib/simplecov/parallel_adapters/base.rb', line 10

def active?
  false
end

.expected_worker_count ⇒ Integer

Returns:

  • (Integer)

# File 'lib/simplecov/parallel_adapters/base.rb', line 29

def expected_worker_count
  1
end

.first_worker? ⇒ Boolean

Returns:

  • (Boolean)

# File 'lib/simplecov/parallel_adapters/base.rb', line 14

def first_worker?
  true
end

.forced_off? ⇒ Boolean

mutant:disable — false is a singleton, so comparing against it answers the same through ==, eql? and equal?, and no example can tell the three apart.

Returns:

  • (Boolean)

# File 'lib/simplecov/parallel_adapters/base.rb', line 36

def forced_off?
  SimpleCov.parallel_tests == false
end

.native_wait? ⇒ Boolean

Whether wait_for_siblings blocks until every sibling process has exited, so no further resultset can appear. When true, the reporting worker can accept a settled resultset count below expected_worker_count as final instead of waiting out the whole parallel_wait_timeout.

Returns:

  • (Boolean)

# File 'lib/simplecov/parallel_adapters/base.rb', line 25

def native_wait?
  false
end

.parallel_test_groups_count ⇒ Integer

Unset, empty, non-numeric, and non-positive values all mean 1: an unparseable value must not yield 0 workers, which would end the sibling wait before it started.

Returns:

  • (Integer)

def parallel_test_groups_count
  count = Integer(ENV.fetch("PARALLEL_TEST_GROUPS", nil), exception: false)
  count&.positive? ? count : 1
end

.wait_for_siblings ⇒ void

This method returns an undefined value.
