I have seen that in Mocha tests, but this code looked different to me. I'm looking at https://github.com/google/traceur-compiler/blob/master/test/feature/AsyncFunctions/AlphaRenaming.js . I thought to use done in a Mocha test you have to have a parameter named "done" in the test function. I suppose I was wrong about that.
