.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.

# File 'lib/minitest.rb', line 420


def self.run reporter, options = {}
  pos = options[:filter]

  pos = Regexp.new $1 if pos.kind_of?(String) && pos =~ %r%/(.*)/%

    end
  end
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 461


def self.run_one_method klass, method_name, reporter
  reporter.prerecord klass, method_name
  reporter.record Minitest.run_one_method(klass, method_name)

.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 497


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.

# File 'lib/minitest.rb', line 470

.with_info_handler(reporter, &block)

#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.

end

#skipped? ⇒ `Boolean` (readonly)

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

Raises:

Runs a single method. Needs to return self.

Raises:
