Define characteristics on a test group so that its test definitions can inherit them and the test group run can show them.

In Service Test Management, you can define characteristics on a test group in addition to a test definition. Characteristics describe the properties that are required to run and evaluate a test. When you define them once on the test group, you don't have to repeat them on every test definition in the group.

Each characteristic belongs to either a test group or a test definition, never both. You choose the owner when you create the characteristic, and you can't change it afterward. A test definition that needs a different or additional
characteristic has its own characteristic.

## How test definitions inherit characteristics {#test-group-characteristics__test-group-characteristics-inheritance}

To let a test definition inherit a characteristic from its test group, you map the group characteristic to the test definition. The mapping is a configuration record, so you create it yourself. To change what a test definition inherits, you delete the mapping or add a characteristic that belongs to the test definition.

Each test group characteristic can be mapped once for a given test definition. A characteristic that belongs to a test definition can be the target of only one mapping within the same test group.

After the system selects a test definition, it applies the mapping to decide which characteristics show on the test group run. For details, see [Test group run characteristics](https://www.servicenow.com/docs/79HbAS78z5BGEr4XVEZH_A "Find out which characteristics appear on a test group run and which value is shown when a test group and a test definition define the same characteristic.").

## Selecting test groups by condition {#test-group-characteristics__test-group-characteristics-conditions}

You can add conditions to the relationship between a specification and a test group. The test group applies to a product inventory record only when the record meets the conditions. For details, see [Define conditions for a test group relationship](https://www.servicenow.com/docs/gV4fHKmx0COBFDK1NtBBZw "Add conditions to the relationship between a specification and a test group so that the test group applies only to product inventory records that meet the conditions.").
