Jasmine is one of the popular JavaScript unit testing frameworks which is capable of testing synchronous and asynchronous JavaScript code. Gotcha. So I'm working on a 3.0 version (because that's the first one where withArgs was introduced) and I'm making some quality of life changes as well to some of the method signatures and JSDoc comments to adhere to the official version docs, but I'm noticing some peculiarities that make we wonder how accurate their official docs are.
