Cypress open/run with specific browser version

Question

I would like to open/run a cypress test with a specific Chrome browser version, I found it is possible to force to chrome with --browser chrome or even with beta with --browser chrome:beta but did not found how to run with a specific version, like for instance --browser chrome:94.

Anybody knows if it is possible ? And if yes, how to do it ?

Edit: as mention in an answer there is the possibility to use --browser /path/to/browser but what I want, if possible of course, is something automatic that does not need an installation of specific browser version before run.

Thanks

It doesn't seem possible to install multiple versions of chrome (apart from chrome:beta and chrome:canary). chrome:stable automatically updates itself on the machine.

In any case you want to do it without installing, Docker is one way to go.

There's a range of images here

cypress/browsers:node14.16.0-chrome89-ff86  
cypress/browsers:node14.17.0-chrome91-ff89  
cypress/browsers:node16.5.0-chrome94-ff93       
cypress/browsers:node16.5.0-chrome97-ff96   
cypress/browsers:node16.13.0-chrome95-ff94  

Be aware that Cypress and Node versions that are compatible with different chrome versions, as indicated here

cypress/included:8.5.0  cypress/browsers:node14.17.0-chrome91-ff89
cypress/included:8.6.0  cypress/browsers:node14.17.0-chrome91-ff89
cypress/included:8.7.0  cypress/browsers:node14.17.0-chrome91-ff89
cypress/included:9.0.0  cypress/browsers:node16.5.0-chrome94-ff93
cypress/included:9.1.0  cypress/browsers:node16.5.0-chrome94-ff93
cypress/included:9.1.1  cypress/browsers:node16.5.0-chrome94-ff93
cypress/included:9.2.0  cypress/browsers:node16.5.0-chrome94-ff93
cypress/included:9.2.1  cypress/browsers:node16.5.0-chrome94-ff93
cypress/included:9.3.0  cypress/browsers:node16.5.0-chrome94-ff93
cypress/included:9.3.1  cypress/browsers:node16.5.0-chrome94-ff93
cypress/included:9.4.1  cypress/browsers:node16.5.0-chrome94-ff93

So if you try to run [email protected] with chrome@91 you may get unexpected errors.

You can actually do that by passing the path of old browser installed on your system as mentioned in the cypress docs

cypress run --browser /usr/bin/chromium

cypress open --browser /usr/bin/chromium

You can also create multiple commands under your package.json like:

  "scripts": {
    "chrome:95": "cypress run --browser path to chrome 95",
    "chrome:96": "cypress run --browser path to chrome 96",
    "chrome:97": "cypress run --browser path to chrome 97"
  }

Then directly run your tests like:

npm run chrome:95
