Elliot Winkler 0259d15711 Improve architecture for permit matcher ... Why: * There were architectural issues with how the permit matcher kept track of params instances on which doubles had been placed. Previously we were starting off by taking the ActionController::Parameters class and stubbing the #permit and #require instance method on it -- in other words, we were stubbing #require for all instances of ActionController::Parameters -- then we would stub #permit on a particular instance of ActionController::Parameters that #require returned. What this means is that if for some reason the #permit stub on an individual instance isn't working properly, then the #permit stub on ActionController::Parameters will respond to the invocation. This is exactly what happened for the issue we recently fixed -- if the stubbing were done a different way we wouldn't have run into that issue. * Also, there's no reason to have both ParametersDoubles and SliceOfParametersDoubles classes around. While it's nice that we have a simpler option to use if we don't need the more complex one, we actually don't need a distinction here, and we can afford one class that does both. To satisfy the above: * When stubbing #permit or #require, always do so on an instance of ActionController::Parameters and not the whole class. This way we know exactly which methods are being doubled and it's easier to debug things in the future. * This means that we now stub ActionController::Parameters.new and then place stubs on the returned instance. * Refactor ParametersDoubles and SliceOfParametersDoubles: combine them into a ParametersDoubleRegistry class, but extract the code that stubs ActionController::Parameters.new into a CompositeParametersDoubleRegistry class. * Since this broke one of the tests, modify DoubleCollection so that a method cannot be doubled more than once -- if the method is already doubled then `register_stub` or `register_proxy` does nothing and returns the original Double.		2015-09-29 18:42:08 -06:00
