Selecting an appropriate strategy for software test could be crucial for the success of the whole business. Consider the following scenario. Five software components were re-released into the field during the last three months. Each shipment resulted in a certain component exhibiting a major defect, for a total of three defects. These defects had to be immediately fixed with a hot patches. Other four components did not manifest any failures. Now we are standing in front of the next customer release and trying to decide which component(s) should be tested most prior to release. Which one of the following two strategies is appropriate? Focus testing on the component that failed in every previous release, since defects are usually cluster together. Do not focus testing on the component that failed in previous releases, since, most likely, all defects have been already exhausted there
