Objectives of Control Flow Testing
- Path Coverage: During testing, it makes sure that every path through the program is run at least once.
- Branch Coverage: This guarantees that, during testing, every decision point (branch) in the program is evaluated as true or false at least once.
- Decision Coverage: This guarantees that all potential outcomes are covered by executing each decision point in the program at least once.
- Loop testing: It evaluates how the program performs in various loop scenarios, such as numerous, zero and single iterations.
- Testing Error-Handling Paths: It tests the program’s error and exception handling pathways.
- Multiple condition testing: It involves testing both simple and complicated condition combinations inside decision points.
- Boundary Value Examination: It evaluates how the software behaves when input ranges are pushed to their limits.
- Integration testing: It examines how various software modules or components interact with one another.
- Cyclomatic Complexity Reduction: It determines and reduces the program’s cyclomatic complexity.
Control Flow Software Testing
Control flow testing is a type of software testing that uses a program’s control flow as a model. Control flow testing is a structural testing strategy. This testing technique comes under white box testing. For the type of control flow testing, all the structure, design, code and implementation of the software should be known to the testing team. This type of testing method is often used by developers to test their own code and own implementation as the design, code and the implementation is better known to the developers. This testing method is implemented with the intention to test the logic of the code so that the user requirements can be fulfilled. Its main application is to relate the small programs and segments of the larger programs.
