Review the fields on the Test Characteristic form and the rules that govern which characteristics you can add.
Characteristics are available when the Product Model plugin (com.sn_prd_pm) is 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.").

| Field | Description |
|-|-|
| Characteristic | Service or product characteristic that the test uses. The list excludes characteristics of type attachment and duration. For example, if you select a download speed characteristic for a speed test definition, the test measures download speed. |
| Characteristic option | Option defined for the characteristic. |
| Is Mandatory | Option that makes the characteristic mandatory for the test. |
| Test definition | Test definition that the characteristic belongs to. The system fills in this field when you add the characteristic from a test definition. |
| Test group | Test group that the characteristic belongs to. The system fills in this field when you add the characteristic from a test group. |
[Table 1. Test Characteristic]

## Rules {#test-characteristic-fields__test-characteristic-fields-rules}

* A characteristic belongs to either a test definition or a test group, never both. You select the owner when you create the characteristic, and you can't change it afterward.
* Choice, yes/no, and checkbox characteristics can be added again with a different option until all the options are used. Characteristics of other types can be added once.
* When you publish, a characteristic that has options needs a valid option that isn't repeated. A characteristic that has no options must have no option.

To let a test definition inherit a characteristic from its test group, 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."). For which characteristic appears on a test group run, 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.").
