Software Testing Interview Questions – Part 7
21. Explain Storage Testing.
Testing that verifies the program under test stores data files in the correct directories and that it reserves sufficient space to prevent unexpected termination resulting from lack of space. This is external storage as opposed to internal storage.
22. What is N+1 Testing?
A variation of Regression Testing. Testing conducted with multiple cycles in which errors found in test cycle N are resolved and the solution is retested in test cycle N+1. The cycles are typically repeated until the solution reaches a steady state and there are no errors.

23. What is Testing?
1)The process of exercising software to verify that it satisfies specified requirements and to detect errors.
2)The process of analyzing a software item to detect the differences between existing and required conditions (that is, bugs), and to evaluate the features of the software item (Ref. IEEE Std 829).
3)The process of operating a system or component under specified conditions, observing or recording the results, and making an evaluation of some aspect of the system or component.
24. What is Quality Assurance?
All those planned or systematic actions necessary to provide adequate confidence that a product or service is of the type and quality needed and expected by the customer.
25. What is Quality Circle?
A group of individuals with related interests that meet at regular intervals to consider problems or other matters related to the quality of outputs of a process and to the correction of problems or to the improvement of quality.
26. Explain Software Requirements Specification.
A deliverable that describes all data, functional and behavioral requirements, all constraints, and all validation requirements for software.
27. What is Mutation Testing?
Testing done on the application where bugs are purposely added to it.
28. What is Total Quality Management?
A company commitment to develop a process that achieves high quality product and customer satisfaction.
29. Explain Metric.
A standard of measurement. Software metrics are the statistics describing the structure or content of a program. A metric should be a real objective measurement of something such as number of bugs per lines of code.
30. Define Recovery Testing.
Confirms that the program recovers from expected or unexpected events without loss of data or functionality. Events can include shortage of disk space, unexpected loss of communication, or power out conditions.
