Instance Method Details

#create_generated_attribute(attribute_type, name = "test", index = nil)

Create a ::Rails::Generators::GeneratedAttribute by supplying the attribute type and, optionally, the attribute name:

create_generated_attribute(:string, 'name')

# File 'railties/lib/rails/generators/testing/behaviour.rb', line 83



def create_generated_attribute(attribute_type, name = "test", index = nil)
  Rails::Generators::GeneratedAttribute.parse([name, attribute_type, index].compact.join(":"))
end


  








  

    #generator(args = default_arguments, options = {}, config = {})  
  



  

    

Instantiate the generator.

# File 'railties/lib/rails/generators/testing/behaviour.rb', line 75



def generator(args = default_arguments, options = {}, config = {})
  @generator ||= generator_class.new(args, options, config.reverse_merge(destination_root: destination_root))
end


  








  

    #prepare_destination   (private)
  



  

    

Clears all files and directories in destination.

def prepare_destination # :doc:
  rm_rf(destination_root)
  mkdir_p(destination_root)
end


  








  

    #run_generator(args = default_arguments, config = {})  
  



  

    

Runs the generator configured for this class. The first argument is an array like command line arguments:



class AppGeneratorTest < Rails::Generators::TestCase
  tests AppGenerator
  destination File.expand_path("../tmp", __dir__)
  setup :prepare_destination

  test "database.yml is not created when skipping Active Record" do
    run_generator %w(myapp --skip-active-record)
    assert_no_file "config/database.yml"
  end
end



You can provide a configuration hash as second argument. This method returns the output printed by the generator.
