Blazor-testing from A to Z
summary
Uses Playwright for browser-driven E2E with Chromium, WebApplicationFactory-hosted app on a random localhost port, headless runs and trace ZIPs (screenshots, DOM, network) that replay locally; demonstrates clicking the counter button to get current count equals 1 and controlling the weather API to return a set number of rows for stable asserts. Uses bUnit to render components in-process, inject fake services, inspect component instances (dismissed == true), and uses Verify snapshots with semantic markup comparison to ignore class/attribute ordering. Recommends mixing tools by tradeoffs.
