There are test frameworks for every tier of any application on any platform. People are getting it done. Testing pixel presentation is a problem. Today, Automated macro tests can’t describe in a program how the UI should look before the UI is built. The UI is simply too dynamic and subject to the whims of fashion. But writing tests first for the UI and smoke testing that the UI elements are there and basically function is doable. Most devs struggle keeping their micro testable code seprate from presentation code. TDD is a great way to incur this requirement. Otherwise it needs to be tested in a slow macro UI test. If you’re not familiar with the three tiers of the Test Automation pyramid, give Agile Thoughts episodes 1 through 4 a listen. It takes you through each stage of the pyramid and describes how macro (cutaneous and subcutaneous) and micro complement each other. https://agilenoir.biz/series/agile-thoughts/ https://agilenoir.biz/series/agile-thoughts/
