Presentation transcript:

Cause and Effect Graphing Cause-Effect Graphing is a technique which starts with set of requirements and determines the minimum possible test cases for maximum test coverage which reduces test execution time and ultimately cost. The goal is to reduce the total number of test cases still achieving the desired application quality by covering the necessary test cases for maximum coverage. Cause and Effect

The Cause-Effect graph technique restates the requirements specification in terms of logical relationship between the input and output conditions. Since it is logical, it is obvious to use Boolean operators like AND, OR and NOT. Cause and Effect
