# ATF Code Coverage API

The ATF Code Coverage API provides endpoints to compute code coverage from Automated Test Framework \(ATF\) runs. Coverage can be retrieved by filtered line numbers, for specific script IDs, or for all scripts covered by a set of test suite/test runs.

ATF code coverage is a tool that enables you to determine what percentage of code in a deployment request is covered by ATF test suites.

By default, if ATF test suites cover less than 70% of the code in a deployment request, ReleaseOps transitions the deployment request to the Reconciling state and a test failure task is automatically created. You can adjust the ATF code coverage threshold in the deployment request assessment playbook. For more information, see [Set Automated Test Framework \(ATF\) code coverage](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/application-development/set-atf-code-coverage-threshold.md).

For information on ATF and Performance Analyzer, see [Testing and debugging applications](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/application-development/testing-and-debugging-applications.md).

For information on deployment analyzer, see [Deployment analyzer in ReleaseOps](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/application-development/deployment-analyzer.md).

</table>### Additional information

Large request payloads may be truncated when persisted if the request data exceeds database field limits.

The following fields in the ATF code coverage API requests \[sys\_atf\_code\_coverage\_request\] table are subject to truncation:

-   test\_suite\_results - JSON array of test suite result IDs.
-   test\_results - JSON array of test result IDs.
-   metadata\_info - JSON object containing filtered lines or a script array.

If the **was\_truncated** property is true, details are provided in the **truncation\_message** property of the response body. Additionally, the system logs the following message:

`Field <table_name>.<field_name> truncated from <original_length> to <truncated_length> characters (max: <max_field_length>). Consider increasing column length to prevent data loss"`

The **glide.db.truncate\_utf8** system property truncation behavior:

-   If **glide.db.truncate\_utf8** is true, the information truncates at UTF-8 byte boundaries. This setting is safer for multi-byte characters.
-   If **glide.db.truncate\_utf8** is false \(default\), the information truncates at character boundaries. The default boundary is 4000 characters.

### cURL request

The following example shows how to retrieve the code coverage for a selected test result suite filtered by a specific test script. When **verbose** is `false` or omitted, the **details** object is empty. Only the overall **total** percentage is returned.

```
curl "https://instance.service-now.com/api/now/atf/code_coverage/by_script_id" \
