    .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 318

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.

    .runnable_methods  
  



  

    

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