101⟩ What is Testability?
The degree to which a system or component facilitates the establishment of test criteria and the performance of tests to determine whether those criteria have been met.

“QA Testing Interview Questions and Answers will guide us now that Software QA Testing is an empirical investigation conducted to provide stakeholders with information about the quality of the product or service under test. Software QA Testing also provides an objective, independent view of the software to allow the business to appreciate and understand the risks at implementation of the software.

159 QA Testing Questions And Answers
102⟩ What is System Testing?
Testing that attempts to discover defects that are properties of the entire system rather than of its individual components.
103⟩ What is Structural Testing?
Testing based on an analysis of internal workings and structure of a piece of software. See also White Box Testing.
104⟩ What is Stress Testing?
Testing conducted to evaluate a system or component at or beyond the limits of its specified requirements to determine the load under which it fails and how. Often this is performance testing using a very high level of simulated load.
105⟩ What is 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.
106⟩ What is Static Testing?
Analysis of a program carried out without executing the program.
107⟩ What is Static Analyzer?
A tool that carries out static analysis.
108⟩ What is the difference between QA and testing?
QA is more a preventive thing, ensuring quality in the company and therefore the product rather than just testing the product for software bugs?
TESTING means 'quality control'
QUALITY CONTROL measures the quality of a product
QUALITY ASSURANCE measures the quality of processes used to create a quality product.
109⟩ What is the difference between load and stress testing ?
One of the most common, but unfortunate misuse of terminology is treating “load testing” and “stress testing” as synonymous. The consequence of this ignorant semantic abuse is usually that the system is neither properly “load tested” nor subjected to a meaningful stress test.
Stress testing is subjecting a system to an unreasonable load while denying it the resources (e.g., RAM, disc, mips, interrupts, etc.) needed to process that load. The idea is to stress a system to the breaking point in order to find bugs that will make that break potentially harmful. The system is not expected to process the overload without adequate resources, but to behave (e.g., fail) in a decent manner (e.g., not corrupting or losing data). Bugs and failure modes discovered under stress testing may or may not be repaired depending on the application, the failure mode, consequences, etc. The load (incoming transaction stream) in stress testing is often deliberately distorted so as to force the system into resource depletion.
110⟩ What is Workflow Testing?
Scripted end-to-end testing which duplicates specific workflows which are expected to be utilized by the end-user.
111⟩ What is White Box Testing?
Testing based on an analysis of internal workings and structure of a piece of software. Includes techniques such as Branch Testing and Path Testing. Also known as Structural Testing and Glass Box Testing. Contrast with Black Box Testing.
White box testing is used to test the internal logic of the code.for ex checking whether the path has been executed once, checking whether the branches has been executed at least once .....Used to check the structure of the code.
112⟩ What is Verification?
The process of determining whether of not the products of a given phase of the software development cycle meet the implementation steps and can be traced to the incoming objectives established during the previous phase. The techniques for verification are testing, inspection and reviewing.
113⟩ What is Validation?
The process of evaluating software at the end of the software development process to ensure compliance with software requirements. The techniques for validation is testing, inspection and reviewing.
114⟩ What is Use Case?
The specification of tests that are conducted from the end-user perspective. Use cases tend to focus on operating software as an end-user would conduct their day-to-day activities.
115⟩ What is Usability Testing?
Testing the ease with which users can learn and use a product.
116⟩ What is Traceability Matrix?
A document showing the relationship between Test Requirements and Test Cases.
117⟩ What is Total Quality Management?
A company commitment to develop a process that achieves high quality product and customer satisfaction.
118⟩ What is Top Down Testing?
An approach to integration testing where the component at the top of the component hierarchy is tested first, with lower level components being simulated by stubs. Tested components are then used to test lower level components. The process is repeated until the lowest level components have been tested.
119⟩ What is Thread Testing?
A variation of top-down testing where the progressive integration of components follows the implementation of subsets of the requirements, as opposed to the integration of components by successively lower levels.
120⟩ What is Test Tools?
Computer programs used in the testing of a system, a component of the system, or its documentation.
