`16` `RUNNING AUTOMATED TESTS IN DOCKER`

In this short final chapter, you’ll write a couple of automated tests that verify the state of the Food Finder application. Then you’ll configure a Docker service to continuously run them.

We’ll focus on evaluating the application’s header by using a snapshot test and mocking the user session. We won’t create tests for the other components or our middleware, services, or APIs. However, I encourage you to build these on your own. Try using browser-based end-to-end tests, with a specialized framework such as Cypress or Playwright, to test entire pages. You can find installation instructions and examples ...
