pub struct VisualRegressionTracker { /* private fields */ }

Native Visual Regression Testing infrastructure. Captures and compares frames to detect platform-specific visual differences.

Implementations

impl VisualRegressionTracker

pub fn new( reference_dir: PathBuf, pixel_tolerance: u8, max_mismatched_percentage: f64, ) -> Self

Creates a new VisualRegressionTracker with specified reference folder and tolerances.

pub fn verify_frame(&self, test_name: &str, captured_png: &[u8]) -> bool
