# Run Listeners

Every `run` and `runRaw` methods now accept a `callbacks` argument, which can be a CFC with the right listener methods or a struct with the right closure methods. This will allow you to listen to the testing progress and get information about it. This way you can build informative reports or progress bars.

The available callbacks are:

```javascript
// Called at the beginning of a test bundle cycle
function onBundleStart( target, testResults )
// Called at the end of the bundle testing cycle
function onBundleEnd( target, testResults )

// Called anytime a new suite is about to be tested
function onSuiteStart( target, testResults, suite )
// Called after any suite has finalized testing
function onSuiteEnd( target, testResults, suite )

// Called anytime a new spec is about to be tested
function onSpecStart( target, testResults, suite, spec )
// Called after any spec has finalized testing
function onSpecEnd( target, testResults, suite, spec )
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://testbox.ortusbooks.com/v2.x-1/in-depth/running-tests/run-listeners.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
