Why Mobile Test Automation Needs a Model Context Protocol

Why Mobile Test Automation Needs a Model Context Protocol The recurring pain points After a decade of writing Android UI tests that broke every sprint, I stopped asking how to make selectors more robust. I started asking why we rely on brittle selectors at all. Most frameworks scrape the view hierarchy, then generate XPath or resource‑id strings. Those strings are fragile the minute the UI is refactored. The moment a designer swaps a TextView for a Button with the same label, the test crashes. Setup is another black hole.
