When you want to test a program, there is two types: white box testing and black box testing. Black box testing means you don't need to know about program implements or how it functions. Just program's requirements. White box testing, you must to check every ways your program should go to eliminate bugs.

What is the difference between block box and white box testing?

White box testing or unit testing: To do white box testing, knowledge of internal logic code is required. It is mostly done by developers.Black box testing: The functionality of an application is tested; logic code is not required. This testing is done by testers.Block box or system testing: Testing the application without knowledge of underline code of the application. it is done by the testers.


Which software testing used for test the internal logic?

White box testing or glass box testing.

What is black box testing and white box testing?

Black-Box Testing is a technique of testing without having any knowledge of the interior workings of the application.The tester is oblivious to the system architecture and does not have access to the source code. Typically, while performing a black-box test, a tester will interact with the system's user interface by providing inputs and examining outputs without knowing how and where the inputs are worked upon.White-box testing is the detailed investigation of internal logic and structure of the code. White-box testing is also called glass testing or open-box testing. In order to perform white-box testing on an application, a tester needs to know the internal workings of the code.

What is white box testing in software engineering?

White box testing is when the tester has full access to and knowledge of the unit under test. Black box testing is when he doesen't and is only allowed to enter inputs and verify outputs. Each has advantages.


What is comparison testing in black box testing?

White Box Testing: It is also known as Clear Box Testing or Glass Box or Open Box This is used to find internal functionalities of a software like conditional loops,statement coverage.It is mainly done by the Developers.

What is the difference between a software testing strategy and software testing technique?

A test strategy is a framework that defines the testing methodology of the software development cycle. This includes the testing objective, approaches of testing new functions, types of testing to be performed, total time and resources essential for the project, and the testing environment.In any software testing company, the test strategy describes the test level to be achieved at different levels of testing i.e. unit testing, integration testing, and system testing. For every stage of development design, a corresponding test strategy should be generated to test the new feature sets.Software Testing Technique is nothing but required testing approach to be followed during testing.Testing techniques are as follows:-Static TestingWhite Box TestingBlack Box TestingGrey Box TestingAs software testing is involved in every stage of software life cycle. But, the testing performed at each level of software development is different and has different goals. They can be defined as:Static Testing: Testing of an application without execution on the computer or without executing them through values.White Box Testing: Testing is done on code.Black Box Testing: Testing is done to check the behavior of the application according to customer's requirements.Grey Box Testing: Combination of Black box and white box is called Grey box testing.


What is difference between testing methods testing types testing levels testing techniques?

Hi All, I think the answer for this question is, Testing method :Verification(review) and Validation Testing types : Basically static and dynamic-> in dynamic testing further can be classified into structural(white box) and functional(black box) testing Testing Technique : in white box testing we have 1) loop coverage 2)statement coverage 3) condition coverage 4) decision coverage in black box testing we have 1) Equilance partioning, 2)boundary value analysis 3) error guessing Testing Levels : Unit testing, integration testing systemtesting , Acceptance testing

What is a benefit of combined development testing and operational testing?

Combining development testing and operational testing allows for software testers to do both white box and black box testing. That is, it allows for the code to be tested, while functional requirements are also tested, making for a more smooth development cycle.


What is the fundamental difference between black box and white box testing?

Black Box Testing is a software testing method in which the internal structure/ design/ implementation of the item being tested is NOT known to the tester.Mainly applicable to higher levels of testing:Acceptance Testing,System Testing .Techniques that is used in Black Box testing :-Boundary-value analysis, Error guessing, Race conditions, Cause-effect graphing, Syntax testing, State transition testing, Graph matrix, Equivalence partitioningTechnical background is not the necessity of Black-Box Tester.White Box Testing is a software testing method in which the internal structure/ design/ implementation of the item being tested is known to the tester.Mainly applicable to lower levels of testing:Unit Testing,Integration Testing .Few techniques that are used in white box testing:-Code Coverage, Segment coverage: This is done to ensure that all statement or each line of code has been executed, Compound condition coverage and loop coverage: In this we test all the conditions and all the branching and loops in code, Data Flow testing: we test all the intermediate steps, in this we test how sequential steps behave, Path Testing: In this we test all the path that is defined in code.Through White-Box testing, tester detects all logical errors, design error and Typographical error.


Black box testing in software engineering?

What is the goal of black box testing?

Black-box testing is a term used by software designers and engineers, to describe a method they use to test that the software is working properly. Unlike white-box testing, it examines the software's functionality, without looking at its internal workings.


Which method is better either white box or black box testing explain?

You always need both. What white box testing does is show you what oddball things need to be tested for - like the routine that takes 25% of round-off error, and adds it to my account (If I take it ALL, someone will notice). Black box testing should check the full functionality of the routine and the way it handles erroneous input.


What do you mean by software testing?

Software testing is an execution of a program with the intention of find error. Its black box and white box testing.
