FAQ'S Testing Types

Q76. What is stress 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.
Q77. What is load testing?
A: Load testing simulates the expected usage of a software program, by simulating multiple users that access the program's services concurrently. Load testing is most useful and most relevant for multi-user systems, client/server models, including web servers. For example, the load placed on the system is increased above normal usage patterns, in order to test the system's response at peak loads. You CAN learn load testing, with little or no outside help.

Q79. What is the difference between performance testing and load 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.

Q80. What is the difference between reliability testing and load 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.
Q81. What is the difference between volume testing and load 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.
Q82. What is incremental 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.
Q83. 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. You CAN learn software testing, with little or no outside help. Get CAN get free information. Click on a link!
Q84. What is automated testing?
A: Automated testing is a formally specified and controlled method of formal testing approach.
Q85. What is alpha testing?
A: Alpha testing is final testing before the software is released to the general public. First, (and this is called the first phase of alpha testing), the software is tested by in-house developers. They use either debugger software, or hardware-assisted debuggers. The goal is to catch bugs quickly. Then, (and this is called second stage of alpha testing), the software is handed over to us, the software QA staff, for additional testing in an environment that is similar to the intended use.
Q86. What is beta testing?
A: 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.
Q87. What is the difference between alpha and beta 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.

Q88. What is clear box 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.

Q89. What is boundary value analysis?
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.
Q90. What is ad hoc testing?
A: Ad hoc testing is a testing approach; it is the least formal testing approach.
