Multiple Condition Coverage: A Comprehensive Testing Technique

Multiple Condition Coverage is a software testing technique that ensures that all possible combinations of conditions in a software program are tested. It is also known as MCC or Multiple Condition Decision Coverage (MCDC).

When a software program has multiple conditions, it is important to test all possible combinations of those conditions. This is because, in some cases, a combination of conditions can cause unexpected behavior or errors in the program. MCC ensures that all possible combinations of conditions are tested, thus reducing the risk of errors or bugs in the software.

MCC is a comprehensive testing technique that provides a higher level of assurance that the software program is functioning correctly. It is commonly used in safety-critical systems, such as aviation, medical devices, and nuclear power plants, where the consequences of a software failure can be catastrophic.

To achieve MCC, each condition in the software program is tested in both true and false states. This ensures that all possible combinations of conditions are tested. In addition, each decision in the program is tested independently, ensuring that each decision is exercised at least once.

MCC is a more rigorous testing technique than other coverage criteria, such as statement coverage or branch coverage. It provides a higher level of confidence in the software program’s correctness and reduces the risk of software failures.

In conclusion, Multiple Condition Coverage is a comprehensive testing technique that ensures all possible combinations of conditions in a software program are tested. It is commonly used in safety-critical systems and provides a higher level of assurance that the software program is functioning correctly.
