Feature: ESM loaders support

  I want to nominate one or more loaders to use to transpile my code
  So that I can write my source code in another language
  As a user

  Background:
    Given a file named "features/a.feature" with:
      """
      Feature: some feature
        Scenario: some scenario
          Given a passing step

  Scenario: serial runtime
    When I run cucumber-js with `--loader ts-node/esm --import features/steps.ts`
    Then it passes

  Scenario: parallel runtime
    When I run cucumber-js with `--loader ts-node/esm --import features/steps.ts --parallel 1`
    Then it passes

  Scenario: local loader
