Software Testing-Testing Types

23. What is beta testing in Software Testing?
A: Beta testing is testing an application when development and testing are essentially completed and final bugs and problems need to be found before the final release. Beta testing is typically performed by end-users or others, not programmers, software engineers, or test engineers
Another Definition:- Following alpha testing, "beta versions" of the software are released to a group of people, and limited public tests are performed, so that further testing can ensure the product has few bugs. Other times, beta versions are made available to the general public, in order to receive as much feedback as possible. The goal is to benefit the maximum number of future users.

24. What is stress testing in Software Testing?
A: Stress testing is testing that investigates the behavior of software (and hardware) under extraordinary operating conditions. For example, when a web server is stress tested, testing aims to find out how many users can be on-line, at the same time, without crashing the server. Stress testing tests the stability of a given system or entity. It tests something beyond its normal operational capacity, in order to observe any negative results. For example, a web server is stress tested, using scripts, bots, and various denial of service tools.
Another Definition
Term often used interchangeably with 'load' and 'performance' testing. Also used to describe such tests as system functional testing while under unusually heavy loads, heavy repetition of certain actions or inputs, input of large numerical values, large complex queries to a database system, etc.



25. What is the difference between performance testing and load testing in Software Testing?
A: Load testing is a blanket term that is used in many different ways across the professional software testing community. The term, load testing, is often used synonymously with stress testing, performance testing, reliability testing, and volume testing. Load testing generally stops short of stress testing. During stress testing, the load is so great that errors are the expected results, though there is gray area in between stress testing and load testing.

26. What is the difference between reliability testing and load testing in Software Testing?
A: Load testing is a blanket term that is used in many different ways across the professional software testing community. The term, load testing, is often used synonymously with stress testing, performance testing, reliability testing, and volume testing. Load testing generally stops short of stress testing. During stress testing, the load is so great that errors are the expected results, though there is gray area in between stress testing and load testing.

27. What is the difference between volume testing and load testing in Software Testing?
A: Load testing is a blanket term that is used in many different ways across the professional software testing community. The term, load testing, is often used synonymously with stress testing, performance testing, reliability testing, and volume testing. Load testing generally stops short of stress testing. During stress testing, the load is so great that errors are the expected results, though there is gray area in between stress testing and load testing.



28. What is incremental testing in Software Testing?
A: Incremental testing is partial testing of an incomplete product. The goal of incremental testing is to provide an early feedback to software developers.

29. What is software testing?
A: Software testing is a process that identifies the correctness, completenes, and quality of software. Actually, testing cannot establish the correctness of software. It can find defects, but cannot prove there are no defects.

30. What is automated testing in Software Testing?
A: Automated testing is a formally specified and controlled method of formal testing approach.

31. What is incremental integration testing in Software Testing?
Continuous testing of an application as new functionality is added; requires that various aspects of an application's functionality be independent enough to work separately before all parts of the program are completed, or that test drivers be developed as needed; done by programmers or by testers.

32. What is the difference between alpha and beta testing in Software Testing?
A: Alpha testing is performed by in-house developers and software QA personnel. Beta testing is performed by the public, a few select prospective customers, or the general public.

33. What is clear box testing in Software Testing?
A: Clear box testing is the same as white box testing. It is a testing approach that examines the application's program structure, and derives test cases from the application's program logic. You CAN learn clear box testing, with little or no outside help.

34. What is boundary value analysis in Software Testing?
A: Boundary value analysis is a technique for test data selection. A test engineer chooses values that lie along data extremes. Boundary values include maximum, minimum, just inside boundaries, just outside boundaries, typical values, and error values. The expectation is that, if a systems works correctly for these extreme or special values, then it will work correctly for all values in between. An effective way to test code, is to exercise it at its natural boundaries.
