You can identify errors in a test plan by doing the following:
Review failed process steps
Review the detailed action log These methods allow you to see which process steps did not execute successfully and why they failed. You can also see detailed information about each action performed during the test execution. Re-running the test plan or reviewing canceled actions do not help you identify errors in a test plan, as they do not provide any additional information about the cause of failure.

The purpose of the Test Automation Tool is to perform actions in a simulated user interface on behalf of the assigned test user. The Test Automation Tool is a tool that allows you to execute predefined or custom test scripts for business process testing in your system. The Test Automation Tool does not provide information on your actual tenant configuration, the business app(s) to be used for testing, or populate business data for each test screen. You need to use other tools or apps for those tasks. Reference: https://help.sap.com/viewer/product/SAP_S4HANA_CLOUD/latest/en-US
