# Test a Data Stream
action {#ariaid-title1}

Test your Data Stream action to ensure that it works the way you expect before you add it to a flow.

## Before you begin

* [Create a Data Stream action](https://www.servicenow.com/docs/InueF6RhvElISEeDCBGmoA "Create a reusable action to process a stream of response data within a flow.")
* Role required: action_designer or admin
{#test-data-stream-action__ul_js5_h51_xbb}

## About this task

Testing a Data Stream action returns the first 20 items by default. To change this value, add the com.glide.hub.action_type.datastream.test_max_iterations system property with a value between one and 50.

## Procedure

1. Open the Data Stream action you want to test.
   1. Navigate to Flow DesignerDesigner.
   2. Select the Actions tab.
   3. Select the row for the Data Stream action you want to test.
   {#test-data-stream-action__substeps_cr5_vwp_53b}
2. Select Test.  
   The system displays the Test Action dialog. The contents of the Test Action dialog depend on the Data Stream action inputs.
3. In the Test Action dialog, provide values for any action inputs and select Run Test.
4. Open the Execution Details to ensure that the action executed as expected.  
   The Execution Details Runtime Value returns the first 20 items returned by the Data Stream action.

## What to do next

[Use a Data Stream action in a flow](https://www.servicenow.com/docs/tbtJ4PlckpvLdrNFJ_0L1Q "Data Stream actions use the For each flow logic option to process stream data in a flow. For example, suppose that you want to use a Data Stream action that imports document data from a third-party site. When added to a flow, the action appears as a For each flow logic block, enabling flow designers to easily create a record in ServiceNow for each object in the data stream.").
