Unit tests: * help developer understanding * provide examples for discussion * provide conformance suite for implementors * define boundaries on what is and what is not supported* The tests could use a custom test runner or use an existing one. It would be useful if the testrunner could be run in a browser. It would be helpful to have code comments in the tests, indicating exactly which rules of the spec are being tested, so that the reader can quickly go to that section of the spec (spec in HTML). Real code examples in the spec would be useful, too. I can easily see a bookmarklet used to capture and execute the example selection of the spec. * defining "not supported" could be as simple as having an assertion test that should be ignored, and should be marked ignore, along with a comment as to why the test is ignored (use of Host object, et c). Ignored tests can be a useful form of documentation. > > As Waldemar Horwat (Google) said on the final day, the meeting was > seminal, I like it.
