A number of tests include comments noting that the test function must be executed such that this is the global object.  As the harness is currently implemented, this isn't the case -- this is the test harness object itself.  This breaks a number of tests, of which the example following this email is representative.

Here's a patch to address this problem in the harness and to fix a few tests (only the ones I was immediately examining) to work correctly with it:

What needs to happen for this to be fixed upstream?

     if (desc.value === this.decodeURIComponent &&
         desc.writable === true &&
         desc.enumerable === false && desc.configurable === true) {
         return true;
     }
}

     return fnExists(Object.getOwnPropertyDescriptor);
}
