Which of the following is not always a pre condition for test execution?
-
A properly configured test environment
-
A thoroughly specified test procedure
-
A process for managing identified defects
-
A test Oracle
A thoroughly specified test procedure is helpful but not always a strict precondition. Tests can sometimes be executed with minimal documentation or exploratory approaches. The other options (test environment, defect management, test oracle) are more universally required.
To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) A properly configured test environment - This option is a pre-condition for test execution. Without a properly configured test environment, the tests may not be able to run successfully.
Option B) A thoroughly specified test procedure - This option is not always a pre-condition for test execution. While having a thoroughly specified test procedure can help in executing tests effectively, it is not always necessary. Some testing approaches, such as exploratory testing, may not require a detailed test procedure.
Option C) A process for managing identified defects - This option is a pre-condition for test execution. Test execution is typically followed by defect management, where identified defects are logged, tracked, and managed.
Option D) A test Oracle - This option is a pre-condition for test execution. A test oracle is a mechanism or criterion used to determine the expected outcome of a test. Without a test oracle, it would be difficult to determine whether the test results are correct or not.
The correct answer is Option B) A thoroughly specified test procedure. This option is not always a pre-condition for test execution as some testing approaches may not require a detailed test procedure.
