Meticulous is an AI-powered frontend testing platform that automatically generates and maintains visual end-to-end browser tests, eliminating the need for manual test creation and upkeep. By integrating a simple JavaScript snippet into development, staging, or preview environments, Meticulous records user interactions, capturing clicks, scrolls, and other events. These sessions are analyzed to build a comprehensive test suite that evolves alongside your application, ensuring coverage of every user flow and edge case. When a pull request is opened, Meticulous replays selected sessions on both the base and head commits, capturing visual snapshots after each event. These snapshots are compared to detect behavioral, logical, and visual changes, with results posted directly on the pull request for easy review. To ensure test reliability, Meticulous mocks backend responses, preventing side effects and eliminating the need for special test data setups.
