Testing a web application on every browser and platform is not feasible. See if BrowserStack might solve your web application testing problem. The maturation of web standards like CSS and HTML makes it easier to build robust applications, but support and implementation of those standards is not uniform, so thorough testing is necessary to ensure applications perform as expected. The vast number of browsers and devices used in this always connected world, as well as the rapid product development cycle, make this testing a challenge.
This is where the BrowserStack service enters the picture. BrowserStack provides a way to test web applications on different browsers and operating systems via an easy-to-use web interface.
