# Add a parameter to a test step

Add a variable to a test step to hold a particular type of data when the test runs.

## Before you begin

-   [Create a parameterized test](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/automated-test-framework-atf/create-parameterized-test.md)
-   Role required: atf\_test\_admin, atf\_test\_designer, or admin

## About this task

**Note:** The Run Server Side Script test step is not supported in parameterized tests.

## Procedure

1.  Navigate to **All** > **Automated Test Framework** > **Tests**.

2.  Open a parameterized test.

3.  In the Test Steps related list, create a test step or open an existing step.

4.  Click \[Omitted image "rem-value-icon.png"\] Alt text: Picker icon and select a parameter to add it to a field.

    The parameter displays in the field.

    \[Omitted image "selected-parameter.png"\] Alt text: Selected parameters in the Incident form.


## Result

When the test runs, Automated Test Framework replaces the parameter with test run data.
