Let's test the full widget tree!
summary
Full widget tree testing for Flutter runs the whole app in a test, mocking network at the HTTP wrapper so tests exercise routing, state and UI up to the network layer while keeping runs fast. Setup requires registering dependencies with get_it and stubbing DIO get/post calls via a mock server response manager that maps URLs to JSON files (example uses the free gorest API). Examples: error screen, login + add-post flow, CI and production “post of the day” health checks.
