Decision table testing is a black-box test design technique A table that contains conditions in the rows, test cases in the columns and true/false values in the cells They help creating test cases that rely on multiple conditions Number of test cases = 2 to the power of conditions (in case of binary tables) This number can be reduced on occasions, to reduce effort while maintaining coverage They help visualize test cases, keeps them organized, and easy to read Also assures no permutation is left out With correctly selected conditions it can achieve 100% coverage It can help find gaps in the requirements 3 When to use decision tables? When there are multiple conditions affecting the expected behavior of the feature (e.g.: an online shop where the final price is affected by coupons, user type, etc.) 4 How to use decision tables? Define which conditions are to be included in the table 5 How to use decision tables? Define which conditions are to be included in the table Determine the number of columns based on the conditions 6 How to use decision tables? Define which conditions are to be included in the table Determine the number of columns based on the conditions Fill the table cells with True/False values (make sure to proceed systematically to avoid excluding a combination) 7 How to use decision tables? Define which conditions are to be included in the table Determine the number of columns based on the conditions Fill the table cells with True/False values (make sure to proceed systematically to avoid excluding a combination) Fill the end results 8 How to use decision tables? Define which conditions are to be included in the table Determine the number of columns based on the conditions Fill the table cells with True/False values (make sure to proceed systematically to avoid excluding a combination) Fill the end results Simplify table if possible 9 Exercise 1.
