Cross browser testing – The truth is in the numbers

Wouldn’t this almost be a great viral campaign? This new campaign of one of the world’s leading companies only works properly in Internet Explorer 9.0. In other browsers this is what the Wallmart Video Download service looked like right after launch.

Even though errors like this don’t occur that much anymore most Chrome and Safari users know that there are still quite some annoying bugs when surfing the internet.

The truth is in the numbers

Does this means that developers still can’t be bothered to do cross browser testing? Does it means that companies don’t demand that their web applications work on all browsers? The truth is in the numbers:

IE 6.0, 7.0, 8.0, 9.0, Firefox 3.6, 4.0, 3.5, 5.0, Chrome 12.0, 8.0, 10.0, Safari 5.0 and so on. What works great in IE 9.0 doesn’t automatically work in IE7. Ok. That shouldn’t be hard to find out.

The top at time of writing was: Chrome 13, IE 8.0, Firefox 6, IE9. Only thing is, they add up to about 70%.

One hundred percent
In testing, 100% is impossible. For cross browser testing this is no different. Let’s say you want to test on the browsers used by at least 85% of all people. This means you’d have to have at least 12 dedicated systems running, and being maintained. Not everyone wants this, which is why we have it. As well as a hosted test environment. We have everything running here in our test lab. Almost everything. From IE x.x, Chrome x, Mozilla, and up.

When testing mobile web applications you need to be able to test on mobile handsets. We have a wide coverage of handsets for the big mobile operating systems popular today.

Having all the handsets; hosted test environments; a test lab based on an official Microsoft Developers Network (MSDN) subscription are just some of the reasons why our customer base, including high profile Digital Agencies, are very pleased with the testing we currently perform for them.

At spriteCloud, we are domain experts in AGILE software Quality Assurance and software testing, particularly for web consumer service companies and digital agencies. If testing on all these browser seems daunting, considering allowing us to test your application’s cross-browser and cross-device functionality.
