Determine how testing plugins (Cypress?) can be added to the Drupal Storybook version.

[erichuffman]

The goal is to have framework/example for doing integrated testing of components/prototype pages.

• Look into Cypress and/or Jest(?). Cypress may be best for Drupal environment.
  • Ideally include a testing workflow that targets rendered Storybook pages of individual components and full page prototypes
• Nice to have: a framework/example for visual regression testing
• Nice to have: testing prevents commits if tests fail
