Christian Plesner Hansen announcing Sputnik, Google’s new open source JavaScript test suite:

The goal is not that all implementations should pass all tests. V8 set out with that intention and we learned the hard way that sometimes you have to be incompatible with the spec to be compatible with the web. Rather, we want Sputnik to be a tool for identifying differences between implementations.
