test-fixture

The <test-fixture> element simplifies DOM management in test suites by providing a consistent way to reset and restore DOM state between tests. It helps eliminate non-deterministic test failures caused by leftover DOM changes, reducing boilerplate setup and teardown code.

Key Features

• DOM Reset — Wraps test DOM in a template and creates fresh copies for each test run.
• Automatic Cleanup — Provides a restore() method to clean up fixtured elements after tests.
• Mocha Integration — Includes a helper script (test-fixture-mocha.js) for simplified usage with automatic restoration in Mocha suites.
• Data-Binding Support — Works with data-binding systems like Polymer's dom-bind by supporting a stamp(model) method for templating.
• Complex Templates — Supports multiple and nested templates within a fixture for flexible test scenarios.

Philosophy

The project aims to reduce test fragility by ensuring DOM state is consistently reset, making tests deterministic and easier to maintain without extensive boilerplate.
