Independent Testing Team usually performs this type of testing during the software testing life cycle. Features of Black Box Testing. Non-functional testing – This black box testing type is not related to testing of specific functionality, Non functional testing is concerned with the non-functional requirements and is designed specifically to evaluate the readiness of a system according to the various criteria which are not covered by functional testing. BVA or Boundary Value Analysis: It is one among the useful and critical Black box testing technique that helps in equivalence partitioning. The term is also used to test a website's vulnerability without having any knowledge of the Web server infrastructure (see penetration test). By providing a tester with limited information about the target system, gray-box tests simulate the level of knowledge that a hacker with long-term access to a system … Black box testing or functional testing is a method which is used to examine software functionality without knowing its internal code structure. Advantages and Disadvantages of Black Box Testing. Black Box Testing Method: Black box testing is the Software testing method which is used to test the software without knowing the internal structure of code or program. The following are the techniques employed while using Black box testing for a software application. It is also known as Specifications based testing. It can be applied to all software testing levels but is mostly employed for the higher level acceptance and system related ones. BVA helps in testing any software having a boundary or extreme values. Black-box testing is a ‘software testing technique’ used to examine the functionality of the software instead of bothering about the ‘internal structure’ of the software.It is also termed as behavioral testing as it examines the behavior of the software. Focus in this type of testing is to test the functionality of the software and ensure its conformance with the specified requirements. Black box testing is the type of testing in which an application is tested based on its requirements specifications without the need for knowledge of its internal architecture. Black box testing also known as specification based testing is a software testing type, wherein the testers have no knowledge of the internal structure, design, and code of the software. It tests both functional as well as non-functional requirements of the application. Black Box Model: A black box model is a computer program into which users enter information and the system utilizes pre-programmed logic to return output to the user. Techniques of Black 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 ; 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. Gray-box testing splits the difference between white-box and black-box testing. Black-box testing is a method of software testing that examines the functionality of an application based on the specifications. Most likely this testing method is what most of tester actual perform and used the majority in the practical life. Software Testing can be majorly classified into two categories: .
