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 else can I help you with?
Define software testing. explain its types?
Software testing is the process used to measure the quality of developed computer software.According to definition given by The Institute of Electrical and Electronics Engineers, USA (IEEE) - Software testing is the process of analyzing a software item to detect the differences between existing and required conditions (that is, bugs) and to evaluate the features of the software itemAccording to the definition given by Dave Gelperin and William C. Hetzel - Software testing can be stated as the process of validating and verifying that a software program/application/product:1. meets the requirements that guided its design and development2. works as expected3. can be implemented with the same characteristics4. satisfies the needs of stakeholdersFor the source and more detailed information concerning this subject, click on the related links section (Answers.com) indicated below.
Why software requirement specification is also called black box specification?
It should only specify what the system should do and refrain from stating how to do these. This means that the SRS document should specify the external behavior of the system and not discuss the implementation issues. The SRS document should view the system to be developed as black box, and should specify the externally visible behavior of the system. For this reason, the SRS document is also called the black-box specification of a system.
What is black box flight recorder?
The black box is a object placed in a plane so that if the plane were to crash, scientists could actually tell how it happened because the black box flight recorder would have recorded it all.
Why it is called as Black Box?
because the box is black, and black is associated with death, and no plane crash has a high survivor rate atleast 4 people will die haha, wait that's not funny :\
Does nvidia geforce2 MX400 supports hardware TnL?
Transforming and lighting support is not provided out of the box with the MX400. There is software that will emulate it, but it is just emulation, not native support.
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.
How do you start black box testing and which software is used for this?
Visual Studio has everything for testing software.
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.
What types of software box testing done in early phase of development?
black box
What is a testing method based on an analysis of the specification of a piece of software without reference to its internal workings?
Black Box Testing
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.
Which software testing used for test the internal logic?
White box testing or glass box testing.
What are skills for software engineering?
The candidate for a software engineering job should be certified by Software Engineering Institute in the United States. The knowledge of programming is a prerequisite for the software engineering field, as well as a computer science degree. Many companies require an internship in the field before considering a candidate for a position within their companies. Please see: http://en.wikipedia.org/wiki/Software_engineering for further information.
Difference between software testing tools and techniques?
Software testing techniques are approaches you take towards running a test case. For example at the highest level you may take a black box approach or a white box approach to testing a piece of software. Where with a black box approach you don't understand the internals of the software you are testing but you do know what range of inputs the software can accept and from that you can deduce the expected results. With a white box approach you have a much better understanding of how the software works (perhaps you've been involved in a code review with the developers) and you can create your tests based on exercising the code knowing that the software should do x, y and z with the inputs. Software testing tools however would be employed to help you achieve the approaches you plan to take with testing a piece of software. So taking the black box testing approach discussed above you may use a test data generation tool to help you create the inputs for your black box testing technique. Another example would be using a data comparison test tool to compare expected results with actual results once the tests have been exercised. So in conclusion a test technique describes the approach you might take to test a piece of software, where as a software testing tool would be a method you employ to help you achieve the aims of the software test.
Software testing related interview questions?
Here are 15 software testing interview questions: What is software testing? What is the difference between functional and non-functional testing? What is the difference between manual and automated testing? What are the different types of testing? What is a test case? What is regression testing? What is the difference between black-box and white-box testing? What is the V-Model of software testing? What is exploratory testing? What is smoke testing? What is the difference between severity and priority of a bug? What is the purpose of test automation? What is the defect life cycle? What is the difference between Load Testing, Stress Testing, and Performance Testing? What is the role of a Test Manager in a testing team?
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.
Training in software testing?
Training in software testing equips individuals with essential skills to identify bugs, ensure software quality, and implement testing methodologies effectively. It typically covers manual and automated testing, test case creation, and using tools like Selenium or JIRA. If you're looking for comprehensive training, Uncodemy offers courses in software testing across cities like Noida, Delhi, and Lucknow, providing both practical knowledge and placement assistance to help you build a solid foundation in this field.
