Access window object / browser scope from protractor

I’m running tests with protractor, but it seems impossible to access the JS ‘window’ object. I even tried adding a tag in my html file that would contain something like

var a = window.location;

and then try expect(a) but I couldn’t make it work, I always get undefined references…

How should I process to access variables that are in the browser scope ?

Assuming you are using a recent version of Protractor, let’s say >= 1.1.0, hopefully >= 1.3.1

Attempting to access Browser side JS code directly from Protractor won’t work because Protractor runs in NodeJS and every Browser side code is executed through Selenium JsonWireProtocol.

Without further detail, a working example:

browser.get('https://angularjs.org/');

One-liner promise that, as of today, resolves to '1.3.0-rc.3'

browser.executeScript('return window.angular.version.full;');

You can use it directly in an expect statement given Protractor’s expect resolves promises for you:

expect(browser.executeScript('return window.angular.version.full;')).
toEqual('1.3.0-rc.3');

Longer example passing a function instead of a string plus without expect resolving the promise for you. i.e. for more control and for doing some fancy thing with the result.

browser.driver.executeScript(function() {
return window.angular.version.full;
}).then(function(result) {
console.log('NodeJS-side console log result: ' + result);
//=> NodeJS-side console log result: 1.3.0-rc.3
});
