ViMoTest Prototype - A MPS based prototype for the ViewModel-based Testing approach

In this repository, you can find a prototype where the ViewModel-based Testing (ViMoTest) approach is basically demonstrated. It is based on the language workbench JetBrains MPS, which supports the approach with its projectional editors and powerful language modularity features.

What is ViewModel-based Testing?

ViewModel-based Testing is meant to be an automated testing approach, where (unit) tests are written against a specific abstraction layer, i.e. ViewModels. ViewModels are an architectural pattern, mainly known from the Microsoft’s MVVM (Model-View-ViewModel) pattern.

This approach tries to tackle the problem of fragility in UI-based tests. By using ViewModels, a large portion of the View-Logic (presenter, controller code) can be written isolated from concrete UI frameworks, and enables a good testability.
