You can also go further than this, if wished. There are commercial tools available such as Browserling , Sauce Labs , Browser Stack , Endtest , LambdaTest , TestingBot , and CrossBrowserTesting that do this kind of thing for you, without you having to worry about the setup, if you wish to invest some money in your testing.
It is also possible to set up an environment that automatically runs tests for you, and then only lets you check in your changes to the central code repository if the tests still pass. This is especially prevalent if you are using very new technologies in your site, and you want to test against the latest implementations, or if you are coming across a bug in the latest release version of a browser, and you want to see if the browser's developers have fixed the bug in a newer version.
The first thing to do is to narrow down where the bug occurs as much as possible. Get as much information as you can from the person reporting the bug — what platform s , device s , browser version s , etc.
Try it on similar configurations e. It might not be your fault — if a bug exists in a browser, then hopefully the vendor will rapidly fix it. It might have already been fixed — for example if a bug is present in Firefox release 49, but it is no longer there in Firefox Nightly version 52 , then they have fixed it.
If it is not fixed, then you may want to file a bug see Reporting bugs , below. If it is your fault, you need to fix it! Troubleshooting JavaScript. Once you've discovered what is causing your bug, you need to decide how to work around it in the particular browser it is causing problems in — you can't just change the problem code outright, as this may break the code in other browsers.
The general approach is usually to fork the code in some way, for example use JavaScript feature detection code to detect situations in which a problem feature doesn't work, and run some different code in those cases that does work.
Once a fix has been made, you'll want to repeat your testing process to make sure your fix is working OK, and hasn't caused the site to break in other places or in other browsers. Just to reiterate on what was said above, if you discover bugs in browsers, you should report them:.
This article should have given you a high-level understanding of the most important concepts you need to know about cross browser testing. Armed with this knowledge, you are now ready to move on and start learning about Cross browser testing strategies. Skip to main content Skip to search Skip to select language Learn web development Tools and testing Cross browser testing Introduction to cross browser testing Change language. Overview: Cross browser testing Next This article starts the module off by providing an overview of the topic of cross browser testing, answering questions such as "what is cross browser testing?
Objective: To gain an understanding of the high-level concepts involved in cross browser testing. You need to think about: Different browsers other than the one or two that you use regularly on your devices, including slightly older browsers that some people might still be using, which don't support all the latest, shiniest CSS and JavaScript features. Different devices with different capabilities, from the latest greatest tablets and smartphones, through smart TVs, right down to cheap tablets and even older feature phones that may run browsers with limited capabilities.
People with disabilities, who use the Web with the aid of assistive technologies like screenreaders, or don't use a mouse some people use only the keyboard. Note: We'll cover defensive coding later in the module too.

Cross Browser testing involves testing both the client side and server side behavior of your Web application when it is accessed using different Web Browsers. AppPerfect Web Test can help you test functionality of your web application on client side on different Web Browsers. It ensures compatibility of your application on different Web browsers like Internet Explorer, Firefox, Safari, Chrome etc.
You can record test on any one Web browser and run it on different Web browsers and this way test application's behavior on different browsers without need to re-record test on multiple browsers. Do the following to functional test your application across different Web browsers :.
AppPerfect Load Test can help you test behavior of your web application on server side when application is accessed from different web browsers. Web Server identifies each client by way of User-Agent string.
When Internet users visit a web site, a text string is usually sent in the HTTP header field "User-Agent" to identify the client application.
Web applications often include code to detect client version to adjust the page design sent according to the user agent string received. Do cross-browser and multi-browser mean the same thing? At some places people have used it to mean the same thing.
So, I am bit confused. Cross-browser means something that works across all browsers whereas multi-browser means something that works on, well, multiple browsers. You'll often see people cursing IE for lack of some or the other feature on articles which use latest CSS3 styles to achieve something wonderful. The solutions they present are multi-browser.
When those solutions will start working on IE in a year or so , they will be called cross-browser. Is there a yardstick to define these terms? They are notions and not standards and will remain so since anyone can whip up a browser with minimal support for all of standards.
