Error during Websocket handshake 404/503 when try visit random domain from list

[Artem-Kushch]

Current behavior:

When I try to visit random domain URL from the list, cypress open each domain, but should open one domain. And I have Error during WebSocket handshake 404/503 error (first screenshot) or open some not correct URL (second screenshot).

№1

№2

Desired behavior:

Open one random domain URL without any opens any other domains and errors.

Steps to reproduce: (app code and test code)

describe("Dynamic tests", () => {
  const domains = ["https://github.com", "https://www.google.com", "https://www.wikipedia.org"];
  const randomDomain = chance().pickone(domains);

  it(`Test domain: ${randomDomain}`, () => {
    cy.visit(randomDomain);
  });
});

And try to run this test several times.

    "cypress": "^3.4.1",
    "mocha": "5.2.0",

Can reproduce this. Closing as a duplicate of #1987

// Requires 'npm i chance -D'
let Chance = require('chance')
let chance = new Chance()

describe('Dynamic tests', function () {
  const domains = ['https://github.com', 'https://www.google.com', 'https://www.wikipedia.org']
  const randomDomain = chance.pickone(domains)

  it(`Test domain: ${randomDomain}`, () => {
    cy.visit(randomDomain)
  })
})

Essentially the test is being rerun every time the superdomain under test changes, so that causes the randomDomain to be run again and set to a new domain, etc, forever.
