Explain the need of Random testing and design the random test cases for triangle problem. What is meant by Random testing and design the random test cases for commission program. Give the need of decision table-based testing. Explain with an example, the different parts of decision table. What is meant by decision table-based testing? Develop a decision table for the triangle problem. What is meant by decision table-based testing? Develop a decision table for the NextDate function. Discuss how well decision table testing deals with the multiple fault assumption.
