In the market today, there are a large number of devices with different resolutions and screen sizes. A tough competition exists wherein every client wants their website to run on all these devices.

Testing the same set of test cases on all the available devices in the market today is practically impossible due to the high cost factor, availability of all devices and amount of effort required to test on all these devices. Now a days, most of the websites are being developed as Responsive web design(RWD) websites. The RWD websites layout will adjust based on the screen size and PPI of the device. The main challenge for testing RWD websites is that the automation script generated for one device one platform will only cover the functionality, behavior and workflow. But the same automation script running on different devices ignores the  look and feel, Layout and UI alignment.

This Paper talks about using multiple tools available in the market currently for testing RWD website and our experiences related to them. We have focused majorly  on screenshot analysis and pixel by pixel comparison. We also have capability to execute parallel test cases for RWD website across multiple devices having multiple resolutions in one go along with continuous integration using Selenium and Jenkins.
