1. What’s the Software Testing?
A set of activities conducted with the intent of finding errors in software.

2.What is Acceptance Testing?
Testing conducted to enable a user/customer to determine whether to accept a software product. Normally performed to validate the software meets a set of agreed acceptance criteria.

3. What is Accessibility Testing?
Verifying a product is accessible to the people having disabilities (deaf, blind, mentally disabled etc.).

4.  What is Ad Hoc Testing?
A testing phase where the tester tries to 'break' the system by randomly trying the system's functionality.

5. What is Application Programming Interface (API)?
A formalized set of software calls and routines that can be referenced by an application program in order to access supporting system or network services.

6. What is Backus-Naur Form?
A metalanguage used to formally describe the syntax of a language.

7.  What is Beta Testing?
Testing of a release of a software product conducted by customers.

8. What is Application Binary Interface (ABI)?
A specification defining requirements for portability of applications in binary forms across different system platforms and environments.

9. What is Binary Portability Testing?
Testing an executable application for portability across system platforms and environments, usually for conformation to an ABI specification.

10. What is Black Box Testing?
Testing based on an analysis of the specification of a piece of software without reference to its internal workings. The goal is to test how well the component conforms to the published requirements for the component.

11.  What is Bottom Up Testing?
An approach to integration testing where the lowest level components are tested first, then used to facilitate the testing of higher level components. The process is repeated until the component at the top of the hierarchy is tested.

12. What is Boundary Testing?
Test which focus on the boundary or limit conditions of the software being tested. (Some of these tests are stress tests).

13. What is the difference between verification and validation?
Verification is a review without actually executing the process while validation is checking the product with actual execution. For instance, code review and syntax check is verification while actually running the product and checking the results is validation.

14. What is Bug?
A fault in a program which causes the program to perform in an unintended or unanticipated manner.

15. What is Defect?

16.  What is Branch Testing?
Testing in which all branches in the program source code are tested at least once.

17. What is Breadth Testing?
A test suite that exercises the full functionality of a product but does not test features in detail.

18. What's the Alpha Testing ?
The Alpha Testing is conducted at the developer sites and in a controlled environment by the end user of the software

19. What's the Beta Testing ?
Testing the application after the installation at the client place.

20. What is Component Testing ?
Testing of individual software components (Unit Testing).
