describe('The feature', function() {     
    beforeEach(function () {
       browser.executeScript('localStorage.setItem("key","value");');
    });

   it('should do this', function() {

   });
});

but i get this error when the test is run against selenium with chromedriver 2.10 and chrome 37

Executing: [execute script: window.localStorage.setItem("key","value");, []])
15:31:29.747 WARN - Exception thrown
org.openqa.selenium.WebDriverException: <unknown>: Failed to read the 'localStorage'
property from 'Window': Storage is disabled inside 'data:' URLs.

(Driver info: chromedriver=2.10.267518,platform=Linux 3.11.0-26-generic x86_64) (WARNING:  
The server did not provide any stacktrace information)

Any idea where the problem cam from ?

According to one of the answers at Remove an item from localStorage in a protractor test, this happens when you try to access localStorage without hitting the browser (say, browser.get) first when you are using the Chrome driver. The solution seems to be to hit the browser first (maybe your root page) to get a page loaded in Chrome so that you can manipulate the localStorage. That at least is what I have been doing for our project. Hope this helps!
