How can I force a failure when testing an ADF Webhook?

Question

I would like to try to force a failure when testing an ADF WebHook activity so it follows the failure path. Is there a way I can easily do this? I can try to swap the on success and on failure paths to test the path, but I'd really like to force an actual failure. Should i make it timeout by forcing the timeout to a very small value? Thank you.

@JB - Thanks for the question and using MS Q&A platform.

To force a failure when testing an ADF WebHook activity, you can use the Fail activity. The Fail activity allows you to throw an error in a pipeline intentionally for any reason. You can use it to simulate a failure in your pipeline and test the failure path.

Here are the steps to use the Fail activity:

1. Search for "Fail" in the pipeline Activities pane, and drag a Fail activity to the pipeline canvas.
2. Connect the Fail activity to the WebHook activity.
3. Select the Fail activity on the canvas if it is not already selected, and go to its Settings tab to edit its details.
4. Enter a failure message and error code. These can be literal string expressions, or any combination of dynamic expressions, functions, system variables, or outputs from other activities.

Once you have set up the Fail activity, you can test your pipeline and the WebHook activity will fail, triggering the failure path.

Note that you can also use the Timeout property of the WebHook activity to simulate a failure. By setting the Timeout to a very small value, you can force the WebHook activity to time out and fail. However, this method is less precise than using the Fail activity, as the WebHook activity may fail for other reasons besides timing out.

For more details, refer to Execute a Fail activity in Azure Data Factory and Synapse Analytics.
