run_generator

run_generator(args=self.default_arguments, config={})
public

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.
