How many cases are required to test the tax system specification as described below, using...

A decision table is a technique that shows the possible combinations of conditions and actions for a given problem. A decision table that is not collapsed has one test case for each combination of conditions, regardless of whether the actions are the same or different. The tax system specification has three conditions: salary less than €20,000, married, and number of children between three and four. Each condition has two possible values: true or false. Therefore, the number of test cases for a non-collapsed decision table is 2^3 = 8. References =
