Section 4 introduces our data flow model and testing criteria to measure the comprehensiveness of test sets. Data flow testing is the form of white box testing and structural type testing, which generally keeps check at the points, where the data values are being received by the variables, and at … Data flow testing uses the control flow graph to explore the unreasonable things that can happen to data (data flow anomalies). Data flow testing strategies are family of test strategies to track program’s control flow in order to explore sequences of events related. Section 3 presents the algorithm of constructing an XRG, and our effort to model WS-BPEL applications. In control flow testing we seek to cover all branches or all nodes. What is Workflow Testing? A program's control flow graph (CFG) is used to determine those parts of a program to which a particular value assigned to a variable might propagate. In each level, the definition-use (defuse) chains of the variables of interest are computed, then test data can be generated to cover these defuse chains, in order to fulfill the all-uses criterion. Dataflow Testing focuses on the points at which variables receive values and the points at which these values are used. the technical preliminaries and testing challenges for WS-BPEL applications. When it comes to categorization Data flow testing will can be considered as a type of white box testing and structural types of testing. Use of data-flow testing leads to a richer test suite concentrating on improper use of data due to coding errors.
