JavaScript tests now available on the IE Testing Center

Our commitment to  same markup includes script along with HTML, CSS, SVG, and the other markup that developers use to build the web. To make same markup real, the community needs a set of official tests to assess how interoperable and standards-compliant different browsers are with the latest version of JavaScript, “ECMAScript Fifth Edition” (fondly known as ES5).

As we mentioned in a recent blog post, Ecma International (the standards body behind JavaScript) is working through a process to publish a test suite for ES5. We are contributing tests to this effort, along with other companies.

In the meantime, to make it easier to try out the tests that the standards body is considering, we’re making the ES5 tests we are contributing available on the IE Testing Center.  We’re excited for the official test suite. We’re publishing our submissions to the Ecma test suite now so that the JavaScript and ES5 community can start providing feedback.

We welcome feedback on these tests via Connect. You can log in with any browser and offer comments and suggestions and bugs on the tests. These are some of the same tests that we use as part of our engineering process in developing IE9. 

As Ecma works through getting the official test suite up and running, we will publish additional tests to the IE Testing Center for the community. We will also, of course, submit these tests to the Ecma sponsored ES5 test suite.

Please visit the IE Testing Center and try them out. We look forward to reading your feedback on these tests as we work together to an official ECMAScript test suite for the community.

Thanks,
Alex Chi
Test Manager, JavaScript
