.run(reporter, options = {})

Responsible for running all runnable methods in a given class, each in its own instance. Each instance is passed to the reporter to record.

end

.run_one_method(klass, method_name, reporter)

Runs a single method and has the reporter record the result. This was considered internal API but is factored out of run so that subclasses can specialize the running of an individual test. See Minitest::ParallelTest::ClassMethods for an example.

# File 'lib/minitest.rb', line 444

.runnable_methods

Each subclass of Runnable is responsible for overriding this method to return all runnable methods. See #methods_matching.

Raises:

(NotImplementedError)

[ GitHub ]

# File 'lib/minitest.rb', line 480


def self.runnable_methods
  raise NotImplementedError, "subclass responsibility"
end

.runnables

Returns all subclasses of Runnable.

.test_order

Defines the order to run tests (:random by default). Override this or use a convenience method to change it for your tests.

#passed? ⇒ `Boolean` (readonly)

Did this run pass?

Note: skipped runs are not considered passing, but they don’t cause the process to exit non-zero.

Raises:

  raise NotImplementedError, "subclass responsibility"
end

#skipped? ⇒ `Boolean` (readonly)

Was this run skipped? See #passed? for more information.

Raises:

# File 'lib/minitest.rb', line 571


def skipped?
  raise NotImplementedError, "subclass responsibility"
end

#time (rw)

The time it took to run.

def result_code
  raise NotImplementedError, "subclass responsibility"
end

#run

Runs a single method. Needs to return self.

Raises:
