There have been a couple of interesting bits of news out of Microsoft over the last couple of days.
Firstly, they submitted a boat load of CSS 2.1 tests to the W3C:
Today, the IE Team is submitting 3784 new test cases to the CSS 2.1 Working Group for inclusion into the CSS 2.1 test suite. These cases were developed since IE8 Beta 2. This brings Microsoft’s contribution to the CSS 2.1 Test Suite to 7005 tests. IE8 RC1 passes all of these tests today. All but 52 of these cases also pass in at least one other major browser. We’re working closely with the CSS working group to swiftly include these in the official test suite. For now, these tests are available at the Windows Internet Explorer Testing Center. The last key element to web layout interoperability is actually passing the tests. IE8 RC1 is the first browser to pass all valid tests in the suite thus meeting the interoperability requirements in the 2.1 spec.
It’s important that the spec, the browser, and the tests all agree on a behavior. This is when web developers really win. While developing these test cases, we found instances where all other browsers implemented something a specific way. That syntax pattern was in pages all over the web, creating a broad dependency on that behavior. In those cases, we proposed a change to the spec and developed an associated test case to ensure the web continues to work and browsers can implement the spec as written. We sincerely hope this helps the committee finish the 2.1 spec and move it into the Recommendation phase.
The post makes it a little hard to know what exactly is open sourced (mentions the runtime, is that everything?). It also doesn’t link to an actually repo. The only code that I can find is this piece which is copyright Microsoft. I have an email into the guys to get more info.
