Cypress: navigator.setAppBadge hangs Cypress on Chrome 83

Created on 9 Apr 2020 · 7Comments · Source: cypress-io/cypress

Current behavior:

Cypress hangs (freezes), indefinitely. CI/CD killed the process after one hour.

This is reproducable - occurs every test run, both in Gitlab CI / Docker, as well as locally.

headless-mode has these issues, headed-mode does not have issues.

Desired behavior:

Cypress finished running (don't care about pass/fail, just that it exists).

Test code to reproduce

reproduce.html

<!doctype html>
<html lang="en">
<head></head>
<body>
<script>
// Note that if you uncomment this line, everything's back to normal:
navigator.setAppBadge(5)
// This related function also causes the issue: 
// navigator.clearAppBadge()
// Here's some (unrelated) context: https://web.dev/badging-api/

document.getElementsByTagName('body')[0].innerText = 'Done'
</script>
</body>
</html>

test_spec.js

describe('Badge Icon', () => {
  it('does not hang cypress', () => {
    cy.visit('./cypress/fixtures/reproduce.html')
    cy.contains('Done')
  })
})

Versions

Cypress: confirmed on 4.3.0 / 4.0.0 / 3.8.3 / 3.8.1, and prior to 3.8.1 this there was no headless mode for Chrome
(assuming that it is the case for all Cypress versions)
OS: Linux
Browser: 
- Chrome 83 has this issue
- Chrome 81 does not have this issue (it passes)
- Electron 80 does not have this issue (it fails because undefined, but that's OK and to be expected)
- Firefox 74 does not have this issue (it fails because undefined, but that's OK and to be expected)
- Firefox 75 does not have this issue (it fails because undefined, but that's OK and to be expected)

Hi,
I also got the same issue in Cypress 4.0.2, 4.1.0 and 4.2.0 and with Chrome 80 as browser.
Cypress freeze after 1 or 2 tests and does not respond anymore.
When I run it in headed mode, I saw that there is a blank page.

@fifteen-berry is your issue related to navigator.setAppBadge?

If not, and if you can narrow it down a little bit (removing lines of code, seeing at which point in the test it hangs, having a reproducable example) - feel free to open up a new issue

@EtienneBruines , Yes it's not link to this specfic case, it's more general I think. I will open a new issue

Chrome 80 - `navigator.setAppBadge()` is not supported (available by default in Chrome 81):

Canary 84 during `cypress open` works

`cypress run --headless --browser chrome:canary` (Canary 84)

Hangs forever. @EtienneBruines In the future, try print DEBUG logs, sometimes it will show the source of handing. DEBUG logs show this message:
