javascript - Run protractor tests with different window sizes? -

i want start 4 different chrome windows run same tests on 4 resolutions. –

i know protractor has feature called multicapabilities, , know can set window size this: browser.manage().window().setsize(320, 480);

but don't find way combine these 2. or there easier way create behaviour

a simple solution comes in mind create for loop in test file switch make tests running 4 times different resolution.

at beginning of specs:

describe('myapp', function () {     (var = 0; < 4; i++) {         switch (i) {             case 0:                 //set resolution 1                 browser.manage().window().setsize(320, 480);                 break;             case 1:                 //set resolution 2                 browser.manage().window().setsize(600, 800);                 break;             case 2:                 //set resolution 3                 browser.manage().window().setsize(768, 1024);                 break;             case 3:                 //set resolution 4                 browser.manage().window().setsize(1080, 1920);                 break;             default:                 return;         }     }     // beforeeach() {...};     // it('should something', function(){...}; });
