Black Box Testing - Online Software Testing Tutorial 1. Graph-based testing methods. g)Black box testing (data driven or input/output driven) is not based on any knowledge of internal design or code. Tests are based on requirements and functionality. Black box testing attempts to derive sets of inputs that will fully exercise all the functional requirements of a system. With the help of an example, explain Graph-based testing Black-box methods based on the nature of the relationships (links) among the program objects (nodes), test cases are designed to traverse the entire graph.

There are typically three methods that Black-box Testing follows, which are namely: Graph-based, Error Guessing and Boundary Value Analysis. The Graph-based method tracks all the objects involved in the test, identifies them and puts them on a graph.

Black-box testing is a method of software testing that examines the functionality of an application without peering into its internal structures or workings. This method of test can be applied virtually to every level of software testing: unit, integration, system and acceptance.It is sometimes referred to as specification-based testing.

White box testing: flow graphs • Syntactic abstraction of source code • Ressembles classical flow charts • Forms the basis for white box test case generation principles • Purpose of white box test case generation: Coverage of the flow graph in accordance with one or more test criteria
