Can you please help me with this? Answer for this is 8.
Income tax is set a flat rate of 20% per annum for all incomes but with 2 exceptions. Tax exemption is given for incomes below 5000 EGP per annum. Also, families with single worker and more than five members get 5% tax reductions. What is the number of test cases generated using decision table testing when having one test case per each table rule ?

[@TMSQUARETECH]

Hi Bincy,
First of all this is not foundation level, its ISTQB Advance level Test Analyst Question. Anyways will give you the answer.
There are 3 conditions here,
1. people above 5000 EGP
2. people below 5000 EGP
3. single worker with more than 5 member
Now in Decision table we follow the truth table concept where in this scenario the number of test cases are 2^3
where 2 - No of Inputs (true and false) & 3 - No of Conditions which comes to 8 test cases.
Please watch the video to understand further ua-cam.com/video/4laaSPdKvf4/v-deo.html

Why the total decision outcome is 8 not 6? I though 8 is the total branch which is used to calculate branch coverage?

[@TMSQUARETECH]

Hi Che, there is a conflict in your question.. Well there are total 8 decisions/branches and only 6 out of them are tested by the given tests.
