# How to get test results
|
||
You can receive callbacks when the active test run, or individual tests, starts and finishes. You can register callbacks by invoking `RegisterCallbacks` on the [TestRunnerApi](./reference-test-runner-api.md) with an instance of a class that implements [ICallbacks](./reference-icallbacks.md). There are four `ICallbacks` methods for the start and finish of both the whole run and each level of the test tree.
|
||
|
||
## Example
|
||
An example of how listeners can be set up:
|
||
|
||
> **Note**: Listeners receive callbacks from all test runs, regardless of the registered `TestRunnerApi` for that instance.
|
||
|
||
``` C#
|
||
public void SetupListeners()
|
||
{
|
||
var api = ScriptableObject.CreateInstance<TestRunnerApi>();
|
||
api.RegisterCallbacks(new MyCallbacks());
|
||
}
|
||
|
||
private class MyCallbacks : ICallbacks
|
||
{
|
||
public void RunStarted(ITestAdaptor testsToRun)
|
||
{
|
||
|
||
}
|
||
|
||
public void RunFinished(ITestResultAdaptor result)
|
||
{
|
||
|
||
}
|
||
|
||
public void TestStarted(ITestAdaptor test)
|
||
{
|
||
|
||
}
|
||
|
||
public void TestFinished(ITestResultAdaptor result)
|
||
{
|
||
if (!result.HasChildren && result.ResultState != "Passed")
|
||
{
|
||
Debug.Log(string.Format("Test {0} {1}", result.Test.Name, result.ResultState));
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
> **Note**: The registered callbacks are not persisted on domain reloads. So it is necessary to re-register the callback after a domain reloads, usually with [InitializeOnLoad](https://docs.unity3d.com/Manual/RunningEditorCodeOnLaunch.html).
|
||
|
||
It is possible to provide a `priority` as an integer as the second argument when registering a callback. This influences the invocation order of different callbacks. The default value is zero. It is also possible to provide `RegisterCallbacks` with a class instance that implements [IErrorCallbacks](./reference-ierror-callbacks.md) that is an extended version of `ICallbacks`. `IErrorCallbacks` also has a callback method for `OnError` that invokes if the run fails to start, for example, due to compilation errors or if an [IPrebuildSetup](./reference-setup-and-cleanup.md) throws an exception. |
