I'm refactoring some custom JavaScript modules written to support our mapping functionality. I'm looking to make them much more unit-testable and be able to plug pieces in and out more easily.My question is related to having UI manipulation and business logic be in the same module. I know that having the UI part makes unit testing a little more difficult. I would think also decoupling the UI part would enable other people to add their own UI layer if they wanted to change the look and feel while still keeping the core functionality.Edit: I'm more working with Dojo modules since that what the mapping API is built on top of. I figured since Dojo comes with it we would use that. I'm finding that Dojo modules don't lend themselves to being easily tested (I tried using Doh and it is the most unintuitive testing framework I've ever worked with). I'm thinking of making more vanilla JS modules and only tried to use what I absolutely need to from Dojo. That's where I got the idea to maybe separate the UI layer from the logic for each module as well.Does anyone have suggestions on how those can be decoupled?
