It covers new unit and integration tests plus manual checks where automation is difficult. + +## 1. Test Targets and Fixtures +- **Add a `CoreMLPlayerTests` target** with XCTest. +- **Fixtures**: small sample video (landscape) and portrait stills for orientation checks; synthetic pixel buffers in `kCVPixelFormatType_32BGRA` and model-preferred formats; a lightweight mock `MLModel` and `VNCoreMLModel` wrapper for failure injection. +- **Environment**: ensure tests run on device and simulator; gate GPU-dependent tests with `XCTSkip` when `MTLDevice` is unavailable. + +## 2. Model Loading & Configuration +- **Async load success**: `MLModel.load(contentsOf:configuration:)` resolves and returns a non-nil model; configuration respects `computeUnits` and `allowLowPrecisionAccumulationOnGPU`. +- **Compilation fallback**: when passed an uncompiled model URL, verify the code compiles once and caches the compiled URL; subsequent loads reuse the compiled path. +- **Error surfacing**: inject an invalid model and assert the load path propagates errors (no silent failures). +- **Warm-up inference**: after loading, assert a single warm-up request executes without throwing and marks the model as ready for reuse. + +## 3. Vision Request Lifecycle +- **Request reuse**: repeated video frames should reuse the same `VNCoreMLRequest` / `VNSequenceRequestHandler`; track allocations or identifiers to ensure no per-frame recreation. +- **Error handling**: simulate a Vision error (e.g., mismatched pixel buffer attributes) and assert errors are logged/propagated, not swallowed. +- **Crop/scale compliance**: validate `imageCropAndScaleOption` matches the model’s expected input; tests check `.centerCrop` (or configured option) is applied rather than a hard-coded default. + +## 4. Orientation & Pixel Buffer Handling +- **Orientation mapping**: feed landscape and portrait CMSampleBuffers and assert the resolved `CGImagePropertyOrientation` passed to Vision matches the video track orientation. +- **Pixel format selection**: when `idealFormat` is available, `AVPlayerItemVideoOutput` should be initialized with matching pixel buffer attributes; tests confirm the requested attributes and that fallback to BGRA occurs when unsupported. +- **Pixel buffer validity**: confirm the request handler rejects nil or stale pixel buffers and surfaces an error. + +## 5. Inference Output Validation +- **Deterministic outputs**: run inference on a fixed fixture image and assert detections (labels/bounding boxes) stay within a tolerance envelope to catch pre/post-processing regressions. +- **Performance budget**: use `measure` blocks to ensure per-frame inference time stays within the real-time threshold (e.g., <33ms on a supported device) after changes. +- **Max-FPS loop stability**: stress test with rapid frame delivery to ensure no memory growth (via allocations audit) and no dropped frames due to request recreation. + +## 6. UI/Integration Checks +- **Playback overlay**: snapshot tests for the detection overlay view to ensure bounding boxes render in correct orientation and aspect after crop/scale changes. +- **Lifecycle**: start/stop playback multiple times to verify requests/handlers are released and recreated cleanly; assert no crashes when the app re-enters foreground. +- **Error messaging**: inject model load failures and Vision errors and assert user-facing alerts or logs appear (and do not block main thread responsiveness). + +## 7. Manual Verification +- **On-device smoke test**: run the app on a physical device, confirm stable FPS, correct bounding boxes, and no UI hangs when toggling models or playback speed. +- **GPU/CPU toggle**: switch compute units (CPU-only vs. ANE/GPU) to observe consistency and ensure the app handles hardware differences gracefully. + +## 8. Automation Hooks +- Integrate tests into CI with separate schemes for unit/integration and UI snapshot runs. +- Capture performance baselines in CI artifacts for regression tracking. +- Provide toggles/env vars to skip GPU-reliant tests on unsupported runners.
