software engineering short question answer

1. What is Acceptance Testing?
   Testing conducted to enable a user/customer to determine whether to accept a software product. Normally performed to validate the software meets a set of agreed acceptance criteria.
2. What is Black Box Testing?
   Testing based on an analysis of the specification of a piece of software without reference to its internal workings. The goal is to test how well the component conforms to the published requirements for the component.
3. What is the difference between verification and validation?
   Verification is a review without actually executing the process while validation is checking the product with actual execution. For instance, code review and syntax check is verification while actually running the product and checking the results is validation.
4. What is CMM?
   The Capability Maturity Model for Software (CMM or SW-CMM) is a model for judging the maturity of the software processes of an organization and for identifying the key practices that are required to increase the maturity of these processes.
5. . What are the different Ways of doing Black Box testing?
   There are five methodologies most frequently used:
   A)Top down according to budget
   B)WBS (Work Breakdown Structure)
   C)Guess and gut feeling
   D)Early project data
   E)TPA (Test Point Analysis)
   
   
6. What does the mclabe cyclomatic complexity of a program determine?
   Cyclomatic complexity is likely the most widely used complexity metric in software engineering. It describes the complexity of a procedure by measuring the linearly independent paths through its source code.
   
   
7. What is the difference between interoperability and compatibility testing with some examples?
   Interoperatability:-To check if the software can co exist with other supporting softwares in the system
   Compatibility:-To check if the software runs on different types of operating systems according to customer requirements.
8. What is Gray Box Testing?
   A combination of Black Box and White Box testing methodologies testing a piece of software against its specification but using some knowledge of its internal workings.
   
   
9. What is Integration Testing?
   Testing of combined parts of an application to determine if they function together correctly. Usually performed after unit and functional testing. This type of testing is especially relevant to client/server and distributed systems.
   
   
10. 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.
