Hi Kiran

In Browser campatibility testing we test Testing the webiste with multiple browsers, Versions whether the application is working fine.

Correct me if i am wrong

You want to test look and feel issue ... For example flash files IE6 will not support for that you want to install Active x Components. Some images and contents will not align properly for that you want to check CSS files… And we want to check java script enabled or disabled for all browsers for user validation… let me know if you have any queries regarding this testing. I have attached snap shot for clear under standing purpose Kiran.Thanks
Example snap shot for Browser Compatibility Testing. Thanks
Browser Compatability means,
The pages which are opened in the browser like IE5.5 or higher version
& not opened in other browsers,like in mozilla fire fox

Open the site
Site will open in both browsers
But you can login only in I.E
Because it is not supporting in Mozilla.

Hi all,

Five simple tips for browser compatibility testing

1. Figure out what browsers are out there - and what the trends are.
* Knowing what are the major browsers out there.
This should direct our efforts in terms of how much time we focus when trying to ensure our site is compatible with browser X or Y.
* Observing trends.
From the example I gave above - Firefox is on the rise (and its not just from that source). So, thinking that we don’t have to spend lots of time on Firefox compatibility will come back to haunt is, especially if it’s growing at that rate.

2. Simple and manual tests are the best
Installing multiple versions of browsers on different operating systems is the best way to test your website for browser compatibility. However, this isn’t necessary the most effective way (in terms of time and resources) - but it yields the best outcome.

3. Virtualise where possible
To save costs on running multiple computers with multiple operating systems - run virtual machines on one box, with many browsers installed on different operating systems. Check out VMWare or Microsoft’s Virtual PC to get started on this.

4. Use tools and products that already exist
There are some tools that try to help you with this:
* BrowserShots.org
This is a free service that lets you test your site on multiple browsers. It simulates a browser on the web for you, and all you have to do is key-in your URL. However, this won’t work for internal sites - only sites facing the web.
* BrowserCam
This is a commercial service that has similar functionality as BrowserShots, but also lets you test mobile devices and PDA compatibility as well. Additionally, it lets you test your site on different operating systems, unlike BrowserShots.org. If you have money to spend on browser testing, consider something like this
* Adobe Dreamwever
If you are working on a basic / small website, browser compatibility testing with Adobe Dreamweaver can be relatively easy. Dreamweaver has a built in feature that scans your code for things such as JavaScript that might work on IE but not Firefox. It then produces a simple report summarizing issues that may arise between platforms.

5. Don’t forget mobile and other devices
Because mobile usage on the web is on the rise.

Every time a design is ready we go about testing it extensively on all kinds, so that the design looks universally alike.
This consistency is important, if you are serious about doing professional design work. When we go about asking, many times we face this that users really do not know which browser they are actually viewing the page in, also sometimes it’s difficult for them to judge which versions of browser they are using.

Especially in the current transitional period of going from IE6 to IE7, and FireFox2 to FireFox 3 where there are significant differences between the two browsers, it gets more important for you to make sure that your design works without problem in all kinds.

Most of the times while we are doing this test, If you see a problem in IE6, it is either working on Firefox or Opera. But ideally it is important that you are must initially test your page in Firefox or Opera, as both of these browsers are the most web standards compliant browser and have abundant resources for testing and debugging markup and code. If your code works in either of those, and the page validates in both html and css, then you can be sure that the webpage should work in all other browsers.

You must not miss doing the Browser compatibility test, cause it will let you to lose visitors if your web pages don’t work on all the popular web browsers. Your web pages may be inconsistent on each browser and the visitors would believe that the website is not professional or is buggy, no one blames the browser.

Browser display problems can basically just kill your web pages, and these display differences are caused by a lot of things such as different browser versions, different computer platforms, screen size, browser bugs, HTML errors, and multiple browsers.

Thanks Ritu for your valuable answer.

Designing and developing websites and applications can be a lot of fun, along with that there is also responsibility to ensure that everyone is receiving the same experience across different devices, browsers, operating systems, resolutions, etc. When you think about it, there is a lot that can go wrong, and most likely your project will never be perfect 100% of the time. But if you don’t, you could lose potential customers. Say for example your website doesn’t render properly in IE9. That customer might simply leave and visit your competitor who did spend time on browser compatibility testing.


Browser compatibility testing is one reason, due to which many developers go with companies providing qa services as they have wide range of resources available for this requirement.

Under browser compatibility testing, compatibility of your website with different browsers like Firefox , Google Chrome , Internet Explorer, Safari etc is checked.

When to perform Browser Compatibility Testing:
- When any webpage has a lot of animation, ActiveX , Java Applet and Dynamic content, then Cross browser testing should be started as soon as it is possible.
- If algorithm is running on Client side then Cross Browser testing should be started.

Common Issues found during Cross Browser testing:
- Inconsistency in Page Layout
- Page Validation not work on certain Browser
- Transaction is not being posted to data-base on clicking submit button or link
- SSL certificate error that has been noticed mainly with lower version of browsers
- Inconsistency in Tab Flow
- Some time pagination error also occurs.



Cross Browser Testing is the type of Compatibility Testing, In which Cross Browser Compatibility Testing Companies Test the application in multiple browsers and make sure it works perfectly and consistently.
