with example for analog clock
Add initial mock test coverage for the steami_screen driver. ## Added - FakeDisplay backend to simulate a display device - Basic property tests: center, radius, max_chars - Core drawing API tests: clear, show, pixel, line, rect, text - Text helpers: title, subtitle, value - Widgets: bar, menu, face - Advanced widgets smoke tests: graph, gauge, compass, watch - Geometry helpers via public API: circle (outline and fill) - Edge cases: empty subtitle, unknown face, invalid position fallback Tests validate that high-level API correctly delegates to the display backend by inspecting recorded calls. ## Notes - Tests access the backend via `dev._d` due to runner scope limitations - No hardware dependency (pure mock) ## Remaining work - Validate exact layout/positions (not just call presence) - Test scaling behavior (text scale, value rendering) - Add snapshot/visual tests (e.g. Pillow backend) - Add hardware tests for real displays (SSD1327, GC9A01) - Improve coverage of edge cases (bounds, clipping, long text)
