WebGL Rendering Tests

These tests launch a headless Chrome instance and execute WebGL tests, manually testing the output or comparing it to an expected snapshot.

Setup

To prepare the tests, first install all dependencies and build the test runner.

yarn
yarn build

Webpack will build a bundle containing the test runner, all tests, and their dependencies.

Next, you need to run a web server serving files from this root directory. Ideally, this runs on port :4444, but the local hostname + port can be configured by setting the RENDER_TEST_HOST environment variable.

With the server running, execute tests by running

yarn test
