Functional black box structural white box from pressman, software engineering a practitioner. As in the case of deterministic testing, test criteria may be related to a model of either the program structure, which defines statistical structural testing, or of its functionality, which defines statistical functional testing.
Functional testing ensures that the requirements or specifications are properly satisfied by the application. The testing can be done either manually or using automation. Specificationbased or functional testing enables us to detect errors in the implementation of functions defined in specifications, but since specifications are often incomplete in practice for some reasons eg, lack of ideas, no time to write, it.

Statement coverage this technique is aimed at exercising all programming statements with minimal tests. Recent advancements in structural testing methods have focused on new parameters by which to detect early glaucoma. Functional testing mainly involves black box testing and it is not concerned about the source code of the application. The main aim is to isolate each unit of the system to identify, analyze and fix the defects. Structural functionalism 1 structural functionalism structural functionalism, or in many contexts simply functionalism, is a broad perspective in sociology and anthropology which sets out to interpret society as a structure with interrelated parts. When the structural inspection and functional testing require an ir imaging device and a nonir imaging device, respectively, the conveyor can displace the objects under inspection from a first position, where the structural inspection takes place, to a second position, where the functional test takes place. Functional testing, structural testing and code reading. Structural testing learning objectives structural testing why. In order to become applicable to functional programming languages it needs, however, some adaption.
