Types of Data Flow Testing

Testing for All-Du-Paths: It Focuses on “All Definition-Use Paths. All-Du-Paths is an acronym for “All Definition-Use Paths.” Using this technique, every possible path from a variable’s definition to every usage point is tested.
All-Du-Path Predicate Node Testing: This technique focuses on predicate nodes, or decision points, in the control flow graph.
All-Uses Testing: This type of testing checks every place a variable is used in the application.
All-Defs Testing: This type of testing examines every place a variable is specified within the application’s code.
Testing for All-P-Uses: All-P-Uses stands for “All Possible Uses.” Using this method, every potential use of a variable is tested.
All-C-Uses Test: It stands for “All Computation Uses.” Testing every possible path where a variable is used in calculations or computations is the main goal of this technique.
Testing for All-I-Uses: All-I-Uses stands for “All Input Uses.” With this method, every path that uses a variable obtained from outside inputs is tested.
Testing for All-O-Uses: It stands for “All Output Uses.” Using this method, every path where a variable has been used to produce output must be tested.
Testing of Definition-Use Pairs: It concentrates on particular pairs of definitions and uses for variables.
Testing of Use-Definition Paths: This type of testing examines the routes that lead from a variable’s point of use to its definition.
