Questions & Answers

Q: What is a decision table and how is it used in software testing?

A decision table is a tool used in software testing to make decisions based on conditions and variables. It helps determine the actions to be taken based on the combination of these conditions and variables.

Q: How does a decision table help in requirement-based testing?

Decision tables are particularly useful in requirement-based testing as they help identify whether the defined values match the given requirements. They ensure that the appropriate actions are taken during coding and validate the input.

Q: Can you provide an example of a decision table?

Sure! Let's consider a decision table for deducting an amount based on the citizen status, spouse's status, and their age. Each combination of conditions and variables will determine the amount to be deducted.

Q: What are the benefits of using decision tables in software development?
