# Map a characteristic

# Map a test group characteristic to a test definition {#ariaid-title1}

Release version: Brazil  
Updated October 26, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Map a characteristic of a test group to a test definition so that the test definition inherits the characteristic from the group.

## Before you begin

The Product Model plugin (com.sn_prd_pm) must be active. See [Plugins installed with Service Test Management](https://www.servicenow.com/docs/Qs8One~cB18gRXIUQRdk1w "Review the plugins that Service Test Management requires and the optional plugins that add characteristics, test decomposition, and conditional test groups.").

Define the characteristic for the test group. See [Define a characteristic for a test group](https://www.servicenow.com/docs/AYX~C0zWkjlm~_ql120AeA "Add a characteristic to a test group so that its test definitions can inherit the characteristic and the test group run can show it.").

Define the characteristic of the test definition that receives the inherited value. The test definition must be in the Draft state. See [Define a characteristic for the test definition](https://www.servicenow.com/docs/3e93NdPa4L2ZzxURWOtrnQ "Add a characteristic for a test to determine the properties that are required to run and evaluate the test.").

Role required: sn_st_mgmt.test_def_creator

## About this task

You create each mapping yourself. The system doesn't create mappings automatically.

## Procedure

1. Navigate to AllService Test ManagementTest DefinitionsAll.
2. Select the draft test definition that you want to open.
3. In the Test Characteristic Attribute Mapping related list, select New.  
   The system fills in the Test definition field.
4. On the form, fill in the fields.  
   {#map-test-group-characteristics-to-test-definition__table_mtg_02b_3cd__entry__2}

   | Field | Description |
   |-|-|
   | Test definition | Test definition that inherits the characteristic. |
   | Source group characteristic | Characteristic of the test group that you want the test definition to inherit. The list shows only characteristics that belong to a test group. |
   | Target definition characteristic | Characteristic that belongs to the selected test definition and receives the inherited value. The list shows only characteristics of the selected test definition that no other mapping in the same test group already uses. |
   [Table 1. Test group characteristic to test definition mapping]

   {#map-test-group-characteristics-to-test-definition__table_mtg_02b_3cd}  
   Note:  
   You can create only one mapping for the same test definition and source characteristic. If you map a target characteristic that another mapping in the same test group already uses, the system doesn't save the record.
5. Select Submit.

## Result

The test definition inherits the characteristic from the test group. To stop inheriting it, delete the mapping.

## What to do next

To define test decomposition rules for a test definition in the test group, see [Define a test decomposition rule](https://www.servicenow.com/docs/o4IthvuAnkJ~qUbUKarwpQ "Add a test decomposition rule to the mapping between a test group and a test definition to specify the characteristic and characteristic option that the rule uses.").

If the test group is in the Draft state, publish it when it is ready. See [Publish a test group](https://www.servicenow.com/docs/f~bNo9ck8VJZFMIWDcIhgA "Publish a test group so that you can relate it to a specification or a product model and your teams see only approved test groups.").
