# TestRunnerApi
The `TestRunnerApi` retrieves and runs tests programmatically from code inside the project, or inside other packages. `TestRunnerApi` is a [ScriptableObject](https://docs.unity3d.com/ScriptReference/ScriptableObject.html).
You can initialize the API like this:
```c#
var testRunnerApi = ScriptableObject.CreateInstance<TestRunnerApi>();
```
> **Note**: You can subscribe and receive test results in one instance of the API, even if the run starts from another instance.
The `TestRunnerApi` supports the following workflows:
* [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)
