Question
Which of the following statements correctly describes the difference between testing anddebugging?a) Testing identifies the source of defects; debugging analyzes the defects and proposesprevention activitiesb) Dynamic testing shows failures caused by defects; debugging eliminates the defects, whichare the source of failuresc) Testing removes faults; but debugging removes defects that cause the faultsd) Dynamic testing prevents the causes of failures; debugging removes the failures
Solution
The correct statement that describes the difference between testing and debugging is:
b) Dynamic testing shows failures caused by defects; debugging eliminates the defects, which are the source of failures
Explanation: Testing is the process of identifying any errors, gaps or missing requirements in comparison with the actual requirements. It is aimed at checking whether the system developed meets the specifications or not. Basically, it is done to find out the defects in the system.
On the other hand, debugging is the process of fixing the identified defects. When a defect is detected, which can be a syntax error, logical error, or semantic error, debugging is done. Debugging tracks the defect, identifies the source of the defect, and corrects it.
