# Define test measure definitions for a service test

Define the values that a test captures, such as the metric, the unit, and how often the value is captured.

## Before you begin

The test definition must be in the Draft state.

Role required: sn\_st\_mgmt.test\_def\_creator

## About this task

Test measure definitions are optional. You can publish a test definition that has no test measure definitions.

## Procedure

1.  Navigate to **All** > **Service Test Management** > **Test Definitions** > **All**.

2.  Select the draft test definition that you want to open.

3.  In the Test Measure Definitions related list, select **New**.

4.  On the form, fill in the fields.

    For the field descriptions, see [Test Measure Definition form fields](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/telecom-media-technology/test-measure-definition-fields.md).

5.  Select **Submit**.


## What to do next

Set the limits that the captured value is checked against. Open the test measure definition that you created, and define a threshold rule from its Threshold Rules related list. See [Define threshold rules for a test measure definition](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/telecom-media-technology/define-threshold-rules.md).
