Final answer:
The primary purpose of a test execution tool is to run automated test scripts to verify the functionality and behavior of a system under test, not to record defects, analyze code, or manage test cases and requirements.
Step-by-step explanation:
The primary purpose of a test execution tool is to run automated test scripts to test the system under test (often referred to as the test object). This usually involves executing a predefined set of instructions created by test engineers to ensure that the software behaves as expected in various conditions and that any defects are identified as early as possible.
Option B, automatically recording defects in the defect tracking system, would typically be a feature integrated into the test execution tool or a separate defect tracking tool rather than its primary function.
Option C, which involves analyzing code for standard violations, is more relevant to static analysis tools. Testing tools' primary function is not to analyze code but to execute tests written for the application.
Option D refers to tasks managed by test management tools, which help in organizing and tracking the status of test cases, defects, and requirements, but are not generally the same as test execution tools.
