## Description

Capybara is a browser automation library and web application acceptance test framework used to simulate user behavior and verify functional requirements. It serves as a cross-browser testing tool and headless browser orchestrator, allowing for the execution of test suites across multiple browser engines.

The project provides a driver-agnostic interaction layer that abstracts different browser engines, enabling users to switch between headless and full browser drivers. It supports multi-user session simulation by maintaining independent browser states and cookies to test interactions between isolated environments.

Its capabilities cover end-to-end browser automation, including user action simulation, web form interaction, and JavaScript execution. The library handles asynchronous content through polling-based synchronization and provides tools for element discovery using CSS and XPath selectors. Additionally, it includes utilities for managing browser windows and modal dialogs, as well as diagnostic features for capturing page states via HTML dumps and screenshots.
