Correct Answer
A. Identifying the cause of a defect, repairing the code and checking the fix is correct.Explanation
Debugging is the process of identifying the cause of a defect in the code, making necessary repairs to the code, and then verifying that the fix has resolved the issue correctly. It involves analyzing the code, locating the source of the problem, and making the necessary changes to eliminate the defect. After the code is repaired, it is important to check the fix to ensure that it has resolved the issue and that no unintended consequences have occurred as a result of the fix.Rate this question:

A test team consistently finds between 90% and 95% of the defects present in the system under test. While the test manager understands that this is a good defect-detection percentage for her test team and industry, senior management and executives remain disappointed in the test group, saying that the test team misses too many bugs. Given that the users are generally happy with the system and that the failures which have occurred have generally been low impact, which of the following testing principles is most likely to help the test manager explain to these managers and executives why some defects are likely to be missed
-
Exhaustive testing is impossible
-
Pesticide paradox
-
Defect clustering
-
Absence-of-errors fallacy
Correct Answer
A. Exhaustive testing is impossibleExplanation
The test manager can explain to the managers and executives that exhaustive testing is impossible, which means that it is not feasible to test every possible combination and scenario in the system. Despite the test team's high defect-detection percentage, it is inevitable that some defects will be missed due to the complexity and vastness of the system. This principle helps to manage expectations and understand that finding every single defect is not realistic or necessary, especially when the users are generally satisfied with the system and the impact of the failures is low.Rate this question:

A programmer is working on code which is very complex. Which of the following is a general testing principle that may affect his work?
-
Defect clustering
-
Component testing
-
Pesticide Paradox
-
Early testing
Correct Answer
A. Defect clusteringExplanation
Defect clustering is a general testing principle that suggests that a small number of modules or components in a software system are responsible for the majority of defects. This means that there tends to be a concentration of defects in certain areas of the code, making it more likely for the programmer to encounter issues while working on complex code. By understanding this principle, the programmer can focus their testing efforts on these specific areas to ensure thorough testing and identify and fix any defects present.Rate this question:

The success of testing is not influenced by the Psychological factor:
-
Gaining confidence about the level of quality and providing information
-
Clear test objectives determine testers effectiveness
-
Blindness to one's own errors
-
Courteous communication and feedback on defects
Correct Answer
A. Gaining confidence about the level of quality and providing informationExplanation
The success of testing is not influenced by the psychological factor of gaining confidence about the level of quality and providing information. This means that regardless of how confident the tester feels about the quality of the product or how much information they provide, it does not directly impact the success of the testing process. Other factors such as clear test objectives, blindness to one's own errors, and courteous communication and feedback on defects play a more significant role in determining the effectiveness of testers.Rate this question:

When there is enough information for sponsors to make an informed decision about release.
-
When time and budget are exhausted.
-
When there are no remaining high priority defects outstanding.
-
When every data combination has been exercised successfully.
Correct Answer
A. When there is enough information for sponsors to make an informed decision about release.Explanation
Testing is considered complete when there is enough information for sponsors to make an informed decision about release. This means that all necessary tests have been conducted and the results have provided sufficient data for sponsors to determine whether the product is ready for release. It does not necessarily mean that all defects have been fixed or that every possible data combination has been tested. The focus is on providing the necessary information for a decision to be made, rather than exhaustively testing every aspect of the product.Rate this question:
