Modified Condition Decision Coverage Research And Implementation Of The Test Criteria

Nowadays software testing plays a great role in a large software project. And it becomes more and more extensive that using Modified Condition/Decision Coverage to generate test cases, later tester test the accuracy of the Boolean expression in the whole program using these cases. In this case, it is very important to research how to create test cases.The thesis introduce two ways ——one way based on truth table andthe other way based on combinations because of priority, through the research of conception and the theories of Modified Condition/ Decision Coverage, and the existent ways which are used to create the test cases of Modified Condition/ Decision Coverage. The inputs of these two ways are Boolean expressions, and these two ways are very simple to use, especially the way which based on combinations because of priority can create these minimal test cases rapidly.At last, this paper introduces how to develop a tool which can create test cases of Modified Condition/Decision Coverage using these two ways by Visual C++, and analyzes these two ways, proofs their excellent capability. These experiments indicate that the way based on combinations because of priority is very available to improve the speed of creating test cases, so it even can improve the speed of software testing.
