I wanted to know which IE versions my readers test on, so I held a survey. The results are below.
Last week I restarted my browser testing, after far too many months of working on the book. I wrote a bunch of new tests, but also wen over my browser test arrays once again. I’m getting tired of old IEs, so I considered removing data for IE7 and below from the desktop tables.
Before doing that, I wanted to make sure this aligns with the interests of my audience. So I created a survey and asked two questions:
IE8 is clearly the new baseline. 45% of respondents indicated that IE8 is the lowest version they test their projects in. 30% is on IE9; 16% on IE10 or 11; and 9% on IE6 or 7. So IE8 should definitely stay in my tables. I never doubted that, but it’s good to have the data to back me up.
Meanwhile I’ve taken my decision; partly based on the survey results, and partly based on the fact IE7 doesn’t run the latest version of my test harness.
I will cease testing in IE7 and below. However, I will keep historical data for these browsers around in a single "IE7 and lower" column.
This only really goes wrong with new tests: if IE8 supports a method or property I never tested before I have to guess if IE7 and lower also support it. In general I assume they support the Microsoft-invented properties, but for others I will occasionally have to add a "Don’t know" entry. If IE8 does not support something I never tested before, I assume IE7 and lower also don’t support it.
Here are the raw data. First Google Drive’s nice graphic:
Then the data table:
How to read: Of all respondents, 705 (45%) test most of their projects in IE8. Of those 705 respondents, 218 (31%) tested in IE7 at least once in the past year.
The IE11-IE5.5 columns don’t add up to 100% because a few respondents were confused and reported, for instance, testing all their sites in IE9 but IE10 being the lowest IE they tested in at all.
There are a few bits of data that merit calling out:
Here are today’s actual IE usage stats, courtesy of StatCounter; IE as a whole stands at 21% of the desktop market (though other sources disagree on that):
