test / error handling / should throw an error if no steps are defined

Code
  test(tests_path, reporter = CucumberProgressReporter$new(), stop_on_failure = FALSE,
  ...)
Output
    Error: 
      Error in `execute(feature, feature_file = feature_path, tags = tags, reporter = reporter)`: No step definitions found.
      i Define steps using `given()`, `when()`, or `then()`.
      i Steps are typically placed in `setup-*.R` files and are loaded automatically by cucumber.
