When any application is deployed the software needs to be tested across multiple platforms and different versions of browsers. It’s tough to maintain environments with different versions of browsers. One approach is to use cloud solutions like Sauce Labs or BrowserStack which provides multi-version-browser support. But in case if you want to build your own environment which is easy to […]
