At the last TC39 meeting we agreed to launch a project to develop an official 
ECMAScript specification test suite that developers and users can use to verify 
that implementations accurately implement the standard.  The hope is that we 
can integrate the various existing test suites along with new tests to create a 
single comprehensive test suite for the ECMAScript standard.

Because of the nature of Ecma's intellectual property policies, only Ecma 
members can directly contribute code to the project.  However, the project code 
will be BSD licensed and development will be carried out in a publically 
accessible manner.  The working name of the test suite is Test262 and I'll be 
serving as the initial project editor. The source code of the project will be 
hosted  in the TS39 repository at  http://hg.ecmascript.org  (coming soon) and 
issues will be tracked at http://bugs.ecmascript.org/report/15 .  In addition, 
I'm setting up a separate  test262-discuss mailing list for topics relating to 
ECMAScript testing and the Test262 test suite. Test262-discuss is open to the 
public. You can subscribe at t http://mail.mozilla.org/listinfo/test262-discuss

I'm now in the early stages of organizing  the project infrastructure and 
collecting initial code contributions from Ecma members. To kick things off, 
Microsoft is contributing the ES5Confrom test suite as well as a significant 
number of additional tests. Christian Plesner Hansen, leader of the Sputnik 
project , reports that Google will contribute their Sputnik code.  Other TC39 
members have all been supportive of this effort and I anticipate that we will 
receive additional contributions from them in the near future.

So, if you're interested in ECMAScript testing subscribe to test262-discuss and 
join in.  After people have had a couple of days to subscribe, I'll be kicking 
things off with some of my ideas about how to structure and organize the 
Test262 suite. Please also share your thoughts.

Thanks,
Allen Wirfs-Brock
