What is a decision table in the context of software testing?

Decision table is a tool that represents a table displaying all possible combinations of conditions and the corresponding system actions. It is used for test design, helping to identify all possible testing scenarios.

Condition 1	Condition 2	Condition n	Action 1	Action 2	Action m
True	True	False	X
True	False	True		X
...	...	...			X

• Rows represent conditions and actions.
• Columns represent rules (combinations of conditions and their corresponding actions).
• An 'X' or checkmark in a cell indicates that the action is performed for that combination of conditions.

Advantages of using:

• Simplifies understanding of complex business logic.
• Ensures comprehensive test coverage, as it covers all condition combinations.
• Helps identify missing or contradictory requirements.
• Serves as a good basis for writing test cases.
