In the context of automated test execution reports, the inclusion of defect clusters is not typically recommended. The primary focus of such reports is to provide a summary of the test execution results, details about the system or application under test along with its version, and the environment in which the tests were executed. Defect clusters, while important in the overall testing process, are generally managed separately from the execution report, often in defect management tools or systems designed for tracking and analyzing defects.

References = The answer is based on the ISTQB CT-TAE guidelines which specify the content that should be included in a test automation report. According to the guidelines, the report should include a summary of the execution results, the system being tested, and the environment in which the tests were run. Defect clusters are not mentioned as part of the report’s content and are therefore considered irrelevant to be included in the test execution report1.
