create_generated_attribute(attribute_type, name = "test", index = nil) Link
Create a Rails::Generators::GeneratedAttribute by supplying the attribute type and, optionally, the attribute name:
create_generated_attribute(:string, "name")
generator(args = default_arguments, options = {}, config = {}) Link
Instantiate the generator.
run_generator(args = default_arguments, config = {}) Link
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.
