Does Selenium's LoadableComponent make sense in a SPA (Single Page Application)?
I can tell you what I do in this situation. I have not used the LoadableComponent, however what I have done has followed a similar pattern. I create classes for each of the "loadable components" that are basically page objects. I have something like the IsLoaded function to ensure that the component is loaded, and depending on how it works I either don't implement a Load function at all, or I have the load function go through the clicks to get the component to load. For example, if loading a component simply means clicking on an item in a menu or some other simple action or sequence of actions, I implement the load function. If it requires doing something more complex such as filling out a form first, I usually do not. In the case where I don't have a Load function, I usually call the IsLoaded functions within other helper functions, so for example if I have a sign up page, I have a function called SignUp that will fill in the form and then call IsLoaded on the page/component that should be loaded next.
