Software Quality Assurance Practice Exam

What is the primary goal of statement execution in software testing?

1. To ensure all executable statements are executed at least once

2. To validate the overall performance of the application

3. To check for syntax errors in the code

4. To evaluate the user interface

The correct answer is: To ensure all executable statements are executed at least once

The primary goal of statement execution in software testing is to ensure that all executable statements within the code are executed at least once. This technique, known as statement coverage, is a critical metric for assessing the completeness of the tests. By executing all statements, testers can identify areas of the code that may not be functioning as intended and ensure that there are no untested paths that could lead to potential defects. This approach focuses on validating the flow of execution through the software, which helps in uncovering issues related to logical errors, uninitialized variables, or missed error handling in the code. High statement coverage can make it easier to ensure that the application behaves as expected under various scenarios. While validating overall performance, checking for syntax errors, and evaluating the user interface are all important facets of software quality assurance, they do not directly relate to the specific goal of statement execution, which is strictly concentrating on the execution of the code itself.
