test patterns
Screen calibration images
Test patterns are standardized images displayed on screens to calibrate or troubleshoot visual equipment.
Television test patterns—geometric shapes, color bars, gradients—were broadcast when programming wasn't airing, becoming nostalgic symbols of late-night TV.
In software development, test patterns are reusable approaches to testing code: We applied common test patterns to validate the API.
