What are decision tables? 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<br>
