Cypress example on waiting for stubbed responses to return

stubbed.response.wait.js

cy.server();

// create aliases
cy.route("activities/*", "fixture:activities").as("getActivities");
cy.route("messages/*", "fixture:messages").as("getMessages");

// visit the dashboard, which should make requests that match
// the two routes above
cy.visit("http://localhost:8888/dashboard");

// pass an array of Route Aliases that forces Cypress to wait
// until it sees a response for each request that matches
// each of these aliases
cy.wait(["@getActivities", "@getMessages"]);

// these commands will not run until the wait command resolves above
cy.get("h1").should("contain", "Dashboard");
