We use [Mocha](https://mochajs.org/) to [test](../../test/index.md) some of our [components](../../test/templates/index.md). Those tests are run by [Karma](https://karma-runner.github.io/latest/index.html) on [travis](https://travis-ci.org/LivelyKernel/lively4-core) <img src="https://travis-ci.org/LivelyKernel/lively4-core.svg">.
