What is CFG in software testing?

In computer science, a control-flow graph (CFG) is a representation, using graph notation, of all paths that might be traversed through a program during its execution.

What is control flow based design?

A control-flow diagram (CFD) is a diagram to describe the control flow of a business process, process or review. Control-flow diagrams were developed in the 1950s, and are widely used in multiple engineering disciplines.

What is a control flow graph how is it used in white box test design?

Node. Nodes in the control flow graph are used to create a path of procedures. Basically, it represents the sequence of procedures which procedure is next to come so, the tester can determine the sequence of occurrence of procedures.

What is Gorilla testing?

Gorilla testing is a software testing technique that repeatedly applies inputs on a module to ensure it is functioning correctly and that there are no bugs. Gorilla testing is a manual testing procedure and is performed on selected modules of the software system with selected test cases.

What is DD path graph?

A decision-to-decision path, or DD-path, is a path of execution (usually through a flow graph representing a program, such as a flow chart) between two decisions.

How control flow optimization is performed?

Control Flow Graph Basic blocks in a program can be represented by means of control flow graphs. A control flow graph depicts how the program control is being passed among the blocks. It is a useful tool that helps in optimization by help locating any unwanted loops in the program.

What is Edge in control flow graph?

Control flow graph is process oriented. Control flow graph shows all the paths that can be traversed during a program execution. Control flow graph is a directed graph. Edges in CFG portray control flow paths and the nodes in CFG portray basic blocks.

What is meant by reducible flow graph?

A reducible flow graph is one that cannot be collapsed to contain such a subgraph. Without such subgraphs, then any cycle of nodes does have a unique header node.

What is difference between control flow and transaction flow?

TRANSACTION FLOW GRAPHS: Transaction flows and transaction flow testing are to the independent system tester what control flows are path testing are to the programmer. The transaction flow graph is to create a behavioral model of the program that leads to functional testing.
