Software Quality Assurance Practice Exam

In software quality assurance, which of the following is not a common type of testing?

1. Regression testing

2. Stress testing

3. Random testing

4. Exploratory testing

The correct answer is: Random testing

Random testing is not typically recognized as a common type of testing in software quality assurance compared to the other methods listed. Regression testing is crucial as it examines whether recent code changes have adversely affected existing functionalities. This type of testing helps ensure that the software continues to perform as expected after updates or bug fixes. Stress testing evaluates how the software behaves under heavy loads or extreme conditions, which is fundamental for understanding its limits and ensuring stability under peak usage scenarios. Exploratory testing involves testers actively exploring the application to identify defects without predefined test cases, relying on their intuition and experience, enhancing the discovery of unexpected issues. In contrast, random testing, while it does exist, is not widely implemented as a formal approach in quality assurance. It typically lacks the focused strategy that the other methods entail, making it less effective for systematic testing endeavors. This singular nature of random testing, along with its uncommon usage in standard practices, solidifies its classification as less common among the typical types of testing in software quality assurance.
