## Screenshot testing Adds visual testing infrastructure for GPUI that captures screenshots by rendering directly to Metal textures. The The screenshots end up in `target/visual_tests/` and look like this: <img width="2560" height="1600" alt="workspace_with_editor2" src="https://github.com/user-attachments/assets/54112343-4af1-4347-9bab-f099de97dd29" /> <img width="2560" height="1600" alt="project_panel2" src="https://github.com/user-attachments/assets/0cd54b61-dace-4398-a28e-0b4d7c2968f6" /> ### Key Features - **Direct texture capture**: Screenshots are captured by rendering the scene to a Metal texture and reading pixels directly from GPU memory, rather than using ScreenCaptureKit - **No visibility requirements**: Windows don't need to be visible on screen since we read directly from the render pipeline - **Deterministic output**: Captures exactly what GPUI renders, not what the OS compositor displays - **No permissions needed**: Doesn't require Screen Recording permission like ScreenCaptureKit would ### Running the Visual Tests ```bash # Run visual tests (compares against baselines) cargo run -p zed --bin visual_test_runner --features visual-tests # Update baseline images (when UI intentionally changes) UPDATE_BASELINE=1 cargo run -p zed --bin visual_test_runner --features visual-tests # View the captured screenshots open target/visual_tests/ ``` ### Implementation - `Window::render_to_image()` - Renders the current scene to a texture and returns an `RgbaImage` - `MetalRenderer::render_to_image()` - Core implementation that renders to a non-framebuffer-only texture - `VisualTestAppContext` - Test context that uses real macOS platform rendering - `VisualTestAppContext::capture_screenshot()` - Synchronous screenshot capture using direct texture rendering ### Usage ```rust let mut cx = VisualTestAppContext::new(); let window = cx.open_window(...)?; let screenshot: RgbaImage = cx.capture_screenshot(window.into())?; ``` Release Notes: - N/A --------- Co-authored-by: Amp <amp@ampcode.com> |
