karma crashes when chrome is already running

[Steditor]

When launching the karma test with chrome already running, three karma tabs open, connect, lose the connection again and then karma crashes. When you close two of the tabs fast enough, everything works.

I am having the same issue

[ncelerier]

Hello,

I've the same problem, except that my configuration is a bit different:

• Windows 7 64 bits, no administrator rights
• Chrome 40.0.2214.91 (Liberkey version)
• Firefox 35 (Liberkey version)
• I'm using these dependencies :

    "karma" : "0.12.31",
    "karma-jasmine" : "0.3.5",
    "karma-chrome-launcher" : "0.1.7",
    "karma-firefox-launcher": "0.1.4",
    "jasmine-core" : "2.2.0",

Note that :

• Even if Chrome is not already launched, Chrome will start and open the three tabs.
• It is working properly when I use Firefox instead of Chrome in the karma browsers variable.
• If I choose not to launch browsers when Karma start, and that I open Chrome and go to http://localhost:9876 manually, everything works properly.

Has anyone of you found a solution to this problem ?

Tell me if I can give you more information.

Thank you.

[MarkusPint]

+1 I have the same problem

[andrevinsky]

The /?id=1231231 part makes the browser freeze. If you manually remove it, it'll get connected. I don't know why.

[cwmrowe]

I'm also getting this problem ever since our IT department changed something in Chrome. Has anyone found a solution?

[parris]

Yea, I'm getting this as well (I think). I found that restarting my computer makes the non-debug mode work better.

[TheSavior]

This has been a problem for us as well recently running with Chrome in Jenkins

[maggialejandro]

Same issue than @ncelerier

OS: WIndow 7 32bits

same dependencies

[paulm-jones]

Same issue, fewer dependencies (no Firefox launcher)

[fi0rini]

Same exact issue - has this been fixed yet?

[kareemaly]

I had the same issue & I didn't have the choice to change to other launcher. So to fix this without changing chrome launcher, I had to set CHROME_BIN ENV to firefox binary!

[ghost]

I am facing the same issue. Is it planned to be fixed?

[horvatic]

Same issue... Here is my package.config: { "devDependencies": { "jasmine-core": "^2.4.1", "karma": "^1.1.1", "karma-chrome-launcher": "^1.0.1", "karma-jasmine": "^1.0.2" } }

We also ran into this when using https://github.com/mark-adams/docker-chromium-xvfb and spawning more than one karma process in parallel]

Edit: We just see a ERROR [launcher]: Chrome crashed. (typically after INFO [launcher]: Starting browser Chrome)

[raghuramrangaraju]

In the configuration file for your project (e.g. karma.config.js), check if you have the plugins listed plugins : [ 'karma-junit-reporter', 'karma-chrome-launcher', 'karma-firefox-launcher', 'karma-opera-launcher', 'karma-ie-launcher', 'karma-jasmine' ],

[wouterpouls]

Somebody who found a solution for this issue?

[johnjbarton]

Has anyone seen this on any platform other than Windows 7?

Just to set expectations: there are no steps to reproduce this issue so someone who has the problem is going to have to dig in and sort it out. Anyone who has this happen every time has a good chance to track it down. For examples: Add logging to karma-chrome-launcher; log the exact commands it issues; try those commands directly.

[spinningarrow]

I’m still seeing this issue on Windows 7. Any pointers on where I should start digging/adding logs?

[pssam]

I have the same issue. I've figured out that the reason is "--user-data-dir" flag in command chrome.exe --user-data-dir=C:\Users\SIARHE~1\AppData\Local\Temp\karma-96883176 --no-default-browser-check --no-first-run --disable-default-apps --disable-popup-blocking --disable-translate --disable-background-timer-throttling --disable-renderer-backgrounding --disable-device-discovery-notifications http://localhost:9876/?id=96883176 Could anyone help me with further steps?

[johnjbarton]

Completely separately I've found that chrome misbehaves if the user-data-dir is not writable. Maybe check that.

[pssam]

I've tried with other folders. It only works if I remove this flag. Moreover, a folder for user data is created successfully by Chrome.
