7.2 Domains and Paths

7.2.1 Meaning of Domain Testing Model

Domain testing can be used to perform functional testing or structural testing. If domain testing is based on specifications, then it is functional test technique. If domain testing is used to verify correctness of implementation then it is a structural technique.

Domain testing is an example of partitions testing. In domain testing strategies the program’s input space is classified into many domains and each such input domain consists of a set of input values that are equivalent in the sense that when any of inputs in particular domain are supplied the programs show the identical behavior. Thus domain testing involves classifying input space into set of partitions, selecting input values from each such partitions, supplying these inputs to a program, and checking whether the program shows expected behavior.
