Using cy.server, cy.route, and cy.wait, we can intercept requests to our real backend, and return known mock responses.

The pros of using this approach:

  • It's much faster than interacting with the real backend
  • Doesn't need to seed data to the backend
  • Easy control of requests and responses
  • Can mock network delay and failure

Cons:

  • No guarantee the stubs match the real backend responses
  • Not full end-to-end testing

Recommended Homework:

  • Mock the route to create a new todo, and reply with a 200
  • Mock the route to edit an existing todo, and reply with a 200

For some reason, cy.route() doesn't want to use my configured baseUrl by default. So I'm having to use Cypress.config().baseUrl to get it to work. Any thoughts as to why?
