# Test groups in Service Test Management

A test group organizes related test definitions and measurement consequences to help identify the root cause of a service problem. Use test groups to define manual or automated testing strategies, apply shared characteristics across test definitions, and limit scope using conditions tied to product inventory records.

A test group contains multiple test definitions and defines the relationships and measurement consequences used to identify the root cause of a service problem.You can define these entities for each test, based on your requirements. The test group contains multiple test definitions.

A test group can also have characteristics that its test definitions inherit. You can limit a test group to specific product inventory records by adding conditions to its relationship with a specification. To configure characteristics that test definitions inherit, see [Test group characteristics](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/telecom-media-technology/test-group-characteristics.md).

You can set up Test groups as either manual or automated:

-   **Manual**

    One or more Test definitions must be attached to the Test group.

-   **Automated**

    You must create a subflow with a list of steps and add it to the group. To run test diagnostics automatically and provide results directly to the agent, create a flow with specific trigger conditions. When a task meets these conditions, the flow runs automatically and displays the test results for the task.


**Note:** ServiceNow provides a demo subflow with demo data for the automated test group. Use this demo flow as a reference for creating subflows for new automated test groups. To learn about the automation framework, see [Service Test Management automation framework](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/telecom-media-technology/stm-automation-framework.md).

To create and configure a test group, see [Setting up a test group](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/telecom-media-technology/setting-test-group.md).
