System Documentation

What problem does it solve?

Missouri-based browser testing turns brittle, ad-hoc UI checks into deterministic tests by modeling an application's UI as a directed graph of states and transitions, and by capturing and comparing browser state after each step (storage, ARIA snapshots, and screenshots).

Core Features & Use Cases

  • State-directory layout where browser state artifacts are stored per transition, including storage.json, ARIA snapshots, and screenshots.
  • Playwright-based transition scripts that drive interactions in a controlled environment and serialize the resulting state for verification.
  • Flexible comparators and verifications to ensure exact or tolerant matches against expected baselines across multiple state artifacts.
  • Deterministic testing workflows that are suitable for CI, offline environments, and repeatable browser automation.

Quick Start

Install Missouri, define a state graph, and run a transition to validate browser interactions.
