Different Cypress baseUrl for cy.visit() and cy.request()

问题

Our application under test locally has a frontend and backend that run on localhost:4200 and 127.0.0.1:8000, respectively.

When calling cy.visit('/somepage') we would like this to have a different baseUrl than for cy.request('/someapi') as cy.visit() will visit a page hosted on the frontend, while cy.request() will make a request to an API endpoint on the backend.

We can use the default baseUrl config from cypress.json for cy.visit(), but is there a way to have cy.request() default to a different config setting than the default baseUrl it uses out of the box? Trying to avoid having to specify this all over the place like cy.request(<fully qualified domain name> + '/someapi'). Thanks!

回答1:

I think you can use config file cypress.env.json to store your API url and get it from each test case.

In your cypress.env.json

"apiUrl": "http://api"

In your test case

describe('get the api variable from config file', () => {
    //set up the variables
    const apiUrl = Cypress.env('apiUrl');
    cy.request(apiUrl + '/someapi');

I do not know about a feature in cypress that allows configuring different baseUrls for visit resp. request.

Since you want to get rid of the boilerplate of setting up the correct API uri per test you could also write a custom command around cy.request:

cypress/support/commands.js

import { API_URI } from '../constants';
// you may want to add a more suitable wrapper depending on the params/options you need to support.
Cypress.Commands.add('api', uri => cy.request(API_URI + uri));

your_spec.js

describe('Foor', () => {
  it('Baar', () => {
    cy.api('/someapi')...
  });
});

BONUS HINT: Be aware that in case no fully qualified domain name (FQDN) is given to cy.request() it behaves stateful by either using the uri of the last cy.visit call or as a fallback baseUrl from cypress config. The approach of this answer is not effected from it, because it always sets the FQDN.
