What Testplane is
Testplane, formerly named Hermione, is a framework for testing web applications across browsers and platforms. Tests use describe and it blocks with TypeScript support and control the page through a browser object. The assertView command compares screenshots with reference images, and a GUI shows diffs for review. Execution options include sharding, parallel runs, isolated browser contexts, remote browser grids, retries and auto-wait. End-to-end tests run in Node.js, while component and unit tests can run in the browser. A plugin system adds custom reporters, commands and execution logic.
