Earlier this year when Internet Explorer 8 Release Candidate was released, the IE team submitted 3784 new test cases to the CSS 2.1 Working Group for inclusion into the CSS 2.1 test suite. And today, the IE team announced that it is submitting 196 new test cases to the CSS 2.1 Working Group for inclusion into the CSS 2.1 test suite.
"Today, the IE Team is submitting 196 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 RC. This brings Microsoft's contribution to the CSS 2.1 Test Suite to 7201 tests. IE8 passes all of these tests today as well as the rest of the tests in the current official CSS 2.1 test suite. We're working closely with the CSS working group to include the new tests in the official test suite. For now, these tests are available at the Windows Internet Explorer Testing Center"
Jason Upton, Test Manager, Internet Explorer, also encouraged other browser vendors to contribute to the W3C's CSS 2.1 test suite so those tests may be used by any browser under the W3C's license.
The test cases can be found at Windows Internet Explorer Testing Center and is available for everyone to test. Please keep in mind that prerequisites might be needed for certain tests and they might fail if not. Upton also mentioned in one of his comments that there are some test case issues that have been raised on the official test suite
"Also take a look at the other test case issues that have been raised on the official test suite. There are some test suite bugs in the official test suite that fail and need to be corrected. https://lists.w3.org/Archives/Public/public...suite/2009Feb/"
In an email sent to IE8 beta participants, Microsoft made it clear that it is still looking for new bugs and users can still submit bugs for IE8 if any.
"We are looking for new IE8 bugs and bugs that have regressed (meaning the bug was previously fixed and now occurs in IE8 RTW). Please only reactivate issues that were resolved as Fixed and reproduce in IE8 RTW. We will automatically resolve any other bug that is reactivated. Please see below for more information on re-activating your bugs.
The Internet Explorer 8 Feedback website on Microsoft Connect will remain open and we will not delete any of your previously submitted bugs.
In the next couple of months, we will introduce a new type of feedback form designed specifically to handle improvements for the next version of Internet Explorer. Please stay tuned for more information."
