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 79
def create_generated_attribute(attribute_type, name = 'test', index = nil)
  Rails::Generators::GeneratedAttribute.parse([name, attribute_type, index].compact.join(':'))
end
generator(args=self.default_arguments, options={}, config={})

Instantiate the generator.

# File railties/lib/rails/generators/testing/behaviour.rb, line 71
def generator(args=self.default_arguments, options={}, config={})
  @generator ||= self.generator_class.new(args, options, config.reverse_merge(destination_root: destination_root))
end
run_generator(args=self.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", File.dirname(__FILE__))
  teardown :cleanup_destination_root

  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.

# File railties/lib/rails/generators/testing/behaviour.rb, line 63
def run_generator(args=self.default_arguments, config={})
  capture(:stdout) do
    args += ['--skip-bundle'] unless args.include? '--dev'
    self.generator_class.start(args, config.reverse_merge(destination_root: destination_root))
  end
end
