decision table is used for testing complex business logics
it is black box testing where it consists of conditions and
actions.conditions are input for which there is an expexted
output which is action this totally forms a rule and each
rule should be a test case.
Decision tables are a precise yet compact way to model complicated logic. Decision tables, like if-then-else and switch-case statements, associate conditions with actions to perform. But, unlike the control structures found in traditional programming languages, decision tables can associate many independent conditions with several actions in an elegant way
It is a table which shows different combination inputs with their associated outputs, this is also known as cause effect table.
In EP and BVA we have seen that these techniques can be applied to only specific conditions or inputs however if we have different inputs which result in different actions being taken or in other words we have a business rule to test where there are different combination of inputs which result in different actions.
For testing such rules or logic decision table testing is used.
