| * `cy.interceptApi({ alias, method = 'POST', urlPattern, triggerFn, onApiResponse })` - intercepts API calls and waits for them to complete. This command will: 1) Register an intercept(in method-alias format e.g. post-myApiAlias) for the given alias & URL pattern if not already registered, 2) Execute the trigger function that makes the API call, 3) Wait for the intercepted request to complete. `alias` is the string for a unique alias for this interception. `method` is the string for the HTTP method (default: 'POST'). `urlPattern` is the string or RegExp for the URL pattern to intercept. `triggerFn` is the function that triggers the API call. `onApiResponse` is an optional callback function that receives the interception object after the API call completes. Use this to perform assertions on the response, extract data, or perform additional actions based on the API result. Default is a no-op function. e.g. `cy.interceptApi({ alias: 'getUsers', method: 'GET', urlPattern: '/api/users', triggerFn: () => cy.get('#load-users').click(), onApiResponse: (interception) => { expect(interception.response.statusCode).to.equal(200); } });` | ||

Use this to perform assertions on the response, extract data, or perform additional actions based on the API result. Default is a no-op function. e.g. `cy.interceptApi({ alias: 'getUsers', method: 'GET', urlPattern: '/api/users', triggerFn: () => cy.get('#load-users').click(), responseInterceptor: (req) => req.reply({ body: { name: "stubbed value" } }), onApiResponse: (interception) => { expect(interception.response.statusCode).to.equal(200); } });` |
There was a problem hiding this comment.
I think I need to see more examples of usage. Are you thinking of stubbing the response with a json fixture?
