| # Extending Unity Test Framework | |
| It is possible to extend the Unity Test Framework (UTF) in many ways, for custom workflows for your projects and for other packages to build on top of UTF. | |
| These extensions are a supplement to the ones already offered by [NUnit](https://github.com/nunit/docs/wiki/Framework-Extensibility). | |
| Some workflows for extending UTF include: | |
| * [How to split the build and run process for standalone Play Mode tests](./reference-attribute-testplayerbuildmodifier.md#split-build-and-run-for-player-mode-tests) | |
| * [How to run tests programmatically](./extension-run-tests.md) | |
| * [How to get test results](./extension-get-test-results.md) | |
| * [How to retrieve the list of tests](./extension-retrieve-test-list.md) |
