Trying to use Chromium on 4.0.0 results in an error

[obartra]

Hey there, I just wanted to give the new version a try and ran into this issue. I don't think it's test specific but let me know if I'm missing something. Thanks for your hard work on v4!

I suspect the issue is a typo on this line

Current behavior:

1. Download and install Chromium 80.0.3987.87 for Mac OS
2. npx cypress open
3. Select "Chromium 80"
4. start a test
5. browser crashes with the following error:

npx cypress open

Desired behavior:

• Tests run

Test code to reproduce

• Use cypress@3.8.3 and run steps described above
• cypress doesn't crash
• Upgrade to cypress@4.0.0 cypress crashes

I also get this error when trying to open Chromium (78) in 4.0.0. This exact download worked in 3.8.3. I have the same path described of /Applications/Chromium.app/Contents/DMacOS/Chromium when logging the browser object.

index.js

module.exports = (on, config) => {
  on('before:browser:launch', (browser = {}, launchOptions) => {
    console.log(browser)
  })
}

3.8.3 browser object

{
  displayName: 'Chromium',
  family: 'chrome',
  isChosen: true,
  majorVersion: 78,
  name: 'chromium',
  path: '/Applications/Chromium.app/Contents/MacOS/Chromium',
  version: '78.0.3904.0',
  isHeaded: true,
  isHeadless: false
}

4.0.0 browser object

{
  channel: 'stable',
  displayName: 'Chromium',
  family: 'chromium',
  isChosen: true,
  majorVersion: 78,
  name: 'chromium',
  path: '/Applications/Chromium.app/Contents/DMacOS/Chromium',
  version: '78.0.3904.0',
  isHeaded: true,
  isHeadless: false
}

Workaround

Find the location that Chromium is installed in and run that with the --browser flag. It's a little tricky and I show how to do this in MacOS in the Gif below. (I'm not sure this drag and drop works on all terminals tbh, I'm using iTerm2)

My path was /Applications/Chromium.app/Contents/MacOS/Chromium

This will pre-select the found browser and it's called Custom Edge 79.

Similarly for cypress run --browser, this will launch and run the tests in Chromium.

For debugging

Logging the browser object after this launch gives the following object.

plugins/index.js

module.exports = (on, config) => {
  on('before:browser:launch', (browser = {}, launchOptions) => {
    console.log(browser)
  })
}

{
  channel: 'stable',
  custom: true,
  displayName: 'Custom Chromium',
  family: 'chromium',
  info: 'Loaded from /Applications/Chromium.app/Contents/MacOS/Chromium',
  isChosen: true,
  majorVersion: 78,
  name: 'chromium',
  path: '/Applications/Chromium.app/Contents/MacOS/Chromium',
  version: '78.0.3904.0',
  isHeaded: true,
  isHeadless: false
}

Hello!

I ran into a similar issue using Chrome 80 when playing around with cypress/included:4.0.0 or Chromium 79 on Ubuntu locally. If I try to run my tests using Chrome, the browser won't start and all I see is the following error:

My tests run perfectly fine when using the following configuration:

• cypress/included:4.0.0 with Electron and Firefox
• cypress/included:3.8.1with Chrome

Unfortunately I can't log browser object to debug. Could that be related, should I create an own issue or do I miss something?
Either way, thank you for your work and help! <3

@leichteckig Have you updated your plugins file according to the migration guide? There were some breaking changes to args in 4.0.0:

https://docs.cypress.io/guides/references/migration-guide.html#Migrating-to-Cypress-4-0

[cypress-bot]

The code for this is done in cypress-io/cypress#6358, but has yet to be released.
We'll update this issue and reference the changelog when it's released.

[cypress-bot]

Released in 4.0.1.
