IE now less than 50% market share – how do you test?

With the news that IE now has less than 50% market share, it might be a good time to review how you test your site’s design and functionality.

Test in mutliple browsers

There’s no set method as all sites have different users who use different browsers and different operating systems. My simple rule of thunb is:

  • If a browser has more than 5% of your user base then fully test it and fix all errors; code and layout.
  • Between 1% and 5%, make sure it works properly but don’t fix minor quibbles.
  • Below 1%, make sure functionality works but don’t worry about layout issues.

Of course, using standards-compliant code will help, as most modern browsers support standards. So spending time agreeing the standards to use is well spent, in the long term.
