What is difference between white box and black box testing?

The Black Box Test is a test that only considers the external behavior of the system; the internal workings of the software is not taken into account. The White Box Test is a method used to test a software taking into consideration its internal functioning. It is carried out by testers.

What is the difference between white box testing and black box testing in which software testing phases they are applicable Why are both necessary?

Black box testing is the Software testing method which is used to test the software without knowing the internal structure of code or program. White box testing is the software testing method in which internal structure is being known to tester who is going to test the software.

What is difference between glass box and white box testing?

White-Box testing is considered as low-level testing. It is also called glass box, transparent box, clear box or code base testing. The white-box Testing method assumes that the path of the logic in a unit or program is known.

What is difference between functional and non functional testing?

Functional testing ensures that functions and features of the application work properly. Nonfunctional testing examines other aspects of how well the application works. Functional testing tests the functionality of an app. Nonfunctional testing tests the performance of these functions.

What is difference between verification and validation?

Validation is the process of checking whether the specification captures the customer's requirements, while verification is the process of checking that the software meets specifications.

Blackbox and Whitebox Testing

What is the difference between static and dynamic testing?

Static testing looks for faults in the code, requirement documents, and design documents, whereas dynamic testing looks at the system's functional behavior, memory/CPU consumption, and overall performance of the system.

What is the difference between regressions and retesting?

In other words, regression testing is about searching for defects, whereas retesting is about fixing specific defects that you've already found. They can therefore occur in one and the same testing process, where: You update your software with a new feature. You test the existing functionality (regression testing)

What is difference between smoke and sanity testing?

Important differences: Smoke vs Sanity testing

Smoke Testing is performed to ascertain that the critical functionalities of the program are working fine. Sanity testing is done at random to verify that each functionality is working as expected. Smoke testing exercises the entire system from end to end.

What is difference between STLC and SDLC?

Software Development Life Cycle (SDLC) is a sequence of different activities performed during the software development process. Software Testing Life Cycle (STLC) is a sequence of different activities performed during the software testing process. SDLC is mainly related to software development.

What is difference between severity and priority?

Severity is “the degree of impact that a defect has on the development or operation of a component or system.” Priority is “the level of (business) importance assigned to an item, e.g., defect.

What is alpha testing and beta testing?

Alpha testing is predominantly about ensuring bug-free functionality. Beta testing involves releasing the software to a limited number of real users. They are free to use it as they want. In other words, this testing is unstructured.

What is defect life cycle?

Defect life cycle, also known as Bug Life cycle is the journey of a defect cycle, which a defect goes through during its lifetime. It varies from organization to organization and also from project to project as it is governed by the software testing process and also depends upon the tools used.

What is API testing?

API testing is a type of software testing that analyzes an application program interface (API) to verify it fulfills its expected functionality, security, performance and reliability.

Who performs Whitebox testing?

The developer will do the white box testing, and they will test all the five programs line by line of code to find the bug. If they found any bug in any of the programs, they will correct it.

What are the two types of Blackbox?

What is the other name of black box testing?

Black Box Testing, also known as functional testing or behavioural testing, essentially requires the testers to evaluate the functionality and usability of the software without looking at the details of the code.

What is difference between bug and defect?

A Bug is the result of a coding Error and A Defect is a deviation from the Requirements. A defect does not necessarily mean there is a bug in the code, it could be a function that was not implemented but defined in the requirements of the software.

What are different types of testing?

What is regression testing?

Regression testing is a software testing practice that ensures an application still functions as expected after any code changes, updates, or improvements. Regression testing is responsible for the overall stability and functionality of the existing features.

What is gamma testing?

Gamma testing is the final stage of the testing process conducted before software release. It makes sure that the product is ready for market release according to all the specified requirements. Gamma testing focuses on software security and functionality.

What is difference between pilot and beta testing?

Pilot testing is performed before the launch of product in the market. Beta testing is performed after the launch of the product. In this testing, feedback comes from some selected users. In beta testing, feedback comes from customer directly.

What is a gray box?

Gray box refers to the testing of software where there is some limited knowledge of its internal workings. Gray box testing is an ethical hacking technique where the hacker has to use limited information to identify the strengths and weaknesses of a target's security network.

What is defect density?

Definition: Defect density can be defined as the number of confirmed bugs in a software application or module during the period of development, divided by the size of the software. Defect density is counted per thousand lines of code, also known as KLOC.

What is blocker in testing?

A blocker might be an issue or bug which you have come across during development or testing and which is not allowing you to develop or test further. Blockers are also known as impediments in Scrum, and issues in more traditional project management approaches.
