Mozilla evangelist accuses Microsoft of promoting internal tests as ‘compliances with web standards’.
Is Internet Explorer 9 a modern browser? If you were to believe this Mozilla evangelist, the answer would be a definite ‘No’.
Just a week after Microsoft released a release candidate for its upcoming browser, Paul Rouget has taken a swipe at the company for bragging about doing well in internal tests.
”Does IE9 support 99% of the HTML5 specification as insinuated by Microsoft? No, they’re actually pretty far from it. The tests Microsoft are referring to are the ones they created during the development of IE9,” he said.
”We score pretty well against our own unit-tests as well. The primary use case for these tests, however, is to spot regressions and validate code changes. In other words: the tests ensure that future changes don’t break the things you just built. They don’t actually test all elements of a specific standard,” he continued.
In his blog post, Rouget used test results from caniuse.com and beta.html5.com to drive his point home. The test results showed that IE9 scored significantly lower than Firefox 4 in both the test scoring only 61% compared to 87% of Firefox 4 in ‘all web standards compatibility’ and 130 compared 255 of Firefox 4 in HTML5 test.
”The reality is that IE9 is 2 years late. Microsoft is glad to come out with the video tag, the canvas tag, SVG, and some CSS3. Like other vendors did years ago. Firefox 3.5 had the video tag, the canvas tag, Geolocation, SVG in 2009. Canvas and SVG existed 5 years ago,” he said.
