cypress: Server is running but 404s on visit to application during cypress run

@embiem try this : https://github.com/cypress-io/cypress/issues/1872#issuecomment-450807452

We’re experiencing a similar issue right now. It looks like cypress reloads the whole page with the baseUrl of the site we want to test instead of cypress’s baseUrl. In more detail:

When no baseUrl is set, we see the test page (where the tests are listed on the left side) at the url http://localhost:56113/__/#/tests/integration\myTestFolder\myTest.spec.js and once we go into the first test and call cy.visit(), the whole page reloads with the http://localhost:3000/__/#/tests/integration\myTestFolder\myTest.spec.js URL, which of course is a 404 on our website. The whole test run is then stuck. It pretty much looks like in the gif @TanvirAlam posted above, where the blank at the end is loading our website which then shows the 404 page.

When we have the baseURL set in the cypress.json, then the test window immediately loads the 404 page. The actual test window is not shown.

This only happens when running the tests in Chrome, but works when running in Electron. We have a dependency on Chrome because of our CI setup.

@jennifer-shehane Just give you little more information as to this is a Laravel vue SPA project run on Docker.

Do I need to install something? like composer? and do npm run dev

So far tried many things ended up with this:

frontend-test:

      - run: npm run test:cypress

Still the same ERROR:

CypressError: cy.visit() failed trying to load:

http://localhost:8080/login

The response we received from your web server was:

  > 404: Not Found

I am so sorry, but I am little new to Cypress and I would really like it if CircleCI could take care of it

Locally, it works just fine

I don’t understand why this was working yesterday without the patch 😞

As far as I understood #1872 it has to do with a chromium update. So if your Chrome browser was updated between yesterday and today, this might be the reason.

@OussamaBaybay thanks, that fixes our issue!

@jennifer-shehane converted mp4 to gif

I’m also having an issue similar to this.
