“Software QA Testing Interview Questions and Answers will guide us that Software QA is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. Software 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. So learn more about Software QA with this Software QA Testing Interview Questions with Answers guide”
251 Software QA Questions And Answers
162⟩ What is Variable trace?
1. "Variable trace" is a (computer) record of the names and the values of variables accessed and/or changed during the execution of a computer program.
2. "Value trace" is same as variable trace. It is a (computer) record of the names and values of variables accessed and/or changed during the execution of a computer program.
163⟩ What is A variant?
"Variants" are versions of a program. Variants result from the application of software diversity.
164⟩ Explain Black-box Testing?
1. Functional testing based on requirements with no knowledge of the internal program structure or data. Also known as closed-box testing.
2. Black box testing indicates whether or not a program meets required specifications by spotting faults of omission -- places where the specification is not fulfilled.
3. Black-box testing relies on the specification of the system or the component that is being tested to derive test cases. The system is a black-box whose behavior can only be determined by studying its inputs and the related outputs
4. Black box testing is functional testing, not based on any knowledge of internal software design or code. Black box testing are based on requirements and functionality.
165⟩ What is A document version?
A document version is an initial release (or complete re-release) of a document, as opposed to a revision resulting from issuing change pages to a previous release.
166⟩ What is version description document (VDD)?
Version description document (VDD) is a document that accompanies and identifies a given version of a software product. Typically the VDD includes the description and identification of the software, identification of the changes incorporated into this version, and the installation and operating information unique to this version of the software.
167⟩ What is virtual address?
In virtual storage systems, virtual addresses are assigned to auxiliary storage locations. The use of virtual addresses allow those locations to be accessed as though they were part of the main storage.
168⟩ What is waiver?
In software QA, a waiver is an authorization to accept software that has been submitted for inspection, found to depart from specified requirements, but is nevertheless considered suitable for use "as is", or after rework by an approved method.
169⟩ What is Clear box testing?
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.
Another term for white-box testing. Structural testing is sometimes referred to as clear-box testing, since “white boxes” are considered opaque and do not really permit visibility into the code. This is also known as glass-box or open-box testing.
170⟩ What is PDR - Peer Design Review?
PDR is an acronym. In the world of software QA or testing, it stands for "peer design review", informally known as "peer review".
171⟩ What is Open box testing?
Open box testing is same as white box testing. It's a testing approach that examines the application's program structure, and derives test cases from the application's program logic.
172⟩ What is Data integrity?
Data integrity is one of the six fundamental components of information security. Data integrity is the completeness, soundness, and wholeness of the data that also complies with the intention of the creators of the data.
In databases, important data - including customer information, order database, and pricing tables - may be stored. In databases, data integrity is achieved by preventing accidental, or deliberate, or unauthorized insertion, or modification, or destruction of data.
173⟩ What is TestDirector?
TestDirector®, also known as Mercury TestDirector®, is a software tool made for software QA professionals. Mercury TestDirector®, as the name implies, is a product made by Mercury Interactive Corporation, 379 North Whisman Road, Mountain View, California 94043 USA.
Mercury's other products include the Mercury QuickTest Professional™, Mercury WinRunner™, also known as WinRunner™, and Mercury Business Process Testing™.
174⟩ What is Constant?
In software or software testing, a constant is a meaningful name that represents a number, or string, that does not change. Constants are variables that remain the same, i.e. constant, throughout the execution of a program.
Why do we, developers, use constants? Because if we have code that contains constant values that keep reappearing, or, if we have code that depends on certain numbers that are difficult to remember, we can improve both the readability and maintainability of our code, by using constants.
To give you an example, we declare a constant and we call it "Pi". We set it to 3.14159265, and use it throughout our code. Constants, such as Pi, as the name implies, store values that remain constant throughout the execution of our program.
Keep in mind that, unlike variables which can be read from and written to, constants are read-only. Although constants resemble variables, we cannot modify or assign new values to them, as we can to variables, but we can make constants public or private. We can also specify what data type they are.
175⟩ Explain a good test engineer?
A good test engineer because he Has a "test to break" attitude, Takes the point of view of the customer, Has a strong desire for quality, Has an attention to detail, He's also Tactful and diplomatic and Has good a communication skill, both oral and written. And he Has previous software development experience, too.
Good test engineers have a "test to break" attitude, they take the point of view of the customer, have a strong desire for quality and an attention to detail. Tact and diplomacy are useful in maintaining a cooperative relationship with developers and an ability to communicate with both technical and non-technical people. Previous software development experience is also helpful as it provides a deeper understanding of the software development process, gives the test engineer an appreciation for the developers' point of view and reduces the learning curve in automated test tool programming.
176⟩ Explain Unit testing?
Unit testing is the first level of dynamic testing and is first the responsibility of developers and then that of the test engineers. Unit testing is performed after the expected test results are met or differences are explainable/acceptable.
177⟩ What is Branch Coverage Testing?
A test method satisfying coverage criteria that requires each decision point at each possible branch to be executed at least once.
178⟩ Explain Branch Testing?
Testing technique to satisfy coverage criteria which require that for each decision point, each possible branch [outcome] be executed at least once. Contrast with testing, path; testing, statement.
179⟩ What is Assertion Testing?
A dynamic analysis technique which inserts assertions about the relationship between program variables into the program code. The truth of the assertions is determined as the program executes.
180⟩ Explain Compatibility testing?
Compatibility testing is testing how well software performs in a particular hardware, software, operating system, or network environment.
