How to test e2e google chrome extension with karma?

Question

I've found fantastic unit/e2e test tools karma. And I wrote simple chrome extension with angular. I want to write automated tests for it, but not only unit tests, end-to-end tests too. I wrote something like this (will open my angular extension-options page):

 it('Go to options page', function() {
   browser().navigateTo('chrome-extension://aopgehikihpnclbfeohobanjecpiefho/html/application.html#/options');
 });

I removed '--user-data-dir' and '--disable-default-apps' for karma-chrome-launcher, (because I want that my extension stays in chrome during "karma tests")

but I've got next error message "Sandbox Error: Application document not accessible.":

    browser navigate to 'chrome-extension://aopgehikihpnclbfeohobanjecpiefho/html/application.html#/options'
    http://localhost:9876/base/tests/e2e/scenario.js?1372429335000:9:5: 

    Sandbox Error: Application document not accessible.

    Chrome 27.0 (Windows): Executed 2 of 2 (2 FAILED) (0.254 secs / 0.139 secs)

Chrome option --no-sandbox deprecated long time ago.

I'm sure I'm not wrong, the options page opens ok, but from chrome "omnibox".

chrome-extension://aopgehikihpnclbfeohobanjecpiefho/html/application.html#/options

Sandbox Error means no way for end-to-end tests for google chrome extensions via karma? Can I set chrome to special "non-secure" mode just for tests?

Thanks,

i don't think karma scenario runner is capable to do that. You can try Protractor, it uses WebDriver and karma scenario runner will be replaced with it.
