# Add test definitions

# Map test definitions to a test group {#ariaid-title1}

Release version: Brazil  
Updated October 13, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Map test definitions to a draft test group and set the order in which they run.

## Before you begin

The test group must be in the Draft state.

Role required: sn_st_mgmt.test_def_creator

## About this task

A manual test group needs at least one test definition before you can publish it. After the test group is published, you can't change its mappings.

## Procedure

1. Navigate to AllService Test ManagementTest GroupsAll.
2. Select the draft test group that you want to open.
3. In the Test Group To Definition Mapping related list, select New.
4. On the form, fill in the fields.  
   {#add-test-definitions-to-test-group__table_group_def_mapping__entry__2}

   | Field | Description |
   |-|-|
   | Test definition | Test definition to add to the test group. Select a definition that is in the Draft or Published state. |
   | Order | Order in which the test definition runs within the test group. Required. |
   | Active | Option that includes the test definition when the test group runs. Selected by default. |
   [Table 1. Test Group To Definition Mapping]

   {#add-test-definitions-to-test-group__table_group_def_mapping}  
   Note:  
   You can map a test definition to a test group only once. If you map it again, the system shows an error.
5. Select Submit.

## What to do next

To enable the test definitions to inherit characteristics from the test group, define the group characteristics before you publish the test group. You can't add or change group characteristics after the test group is published. This requires the Product Model plugin. For more information, 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.").

Map the group characteristics to the test definitions. You can do this while each test definition is in the Draft state. For more information, see [Map a test group characteristic to a test definition](https://www.servicenow.com/docs/DbwzTIlSkvWFsQGO7ALNsg "Map a characteristic of a test group to a test definition so that the test definition inherits the characteristic from the group.").

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.").

When the test group is ready, publish it. 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.").
