## Decision Table Testing: Learn with Example - Shikshaglobe Decision table testing is a black-box testing technique that can be used to test systems with complex decision logic. A decision table is a tabular representation of all the possible inputs and outputs for a system and can be used to test all the possible permutations and combinations of inputs and outputs. Decision table testing is an effective way to test systems with complex decision logic and can be used to find errors that would otherwise be difficult to find.

Decision table testing is a black-box testing technique that can be used to test all combinations of input values and preconditions to determine all possible outputs. It is especially useful for testing complex business rules.

A decision table consists of a set of conditions and actions with each action corresponding to a different output. To test a decision table all possible combinations of inputs and preconditions must be tested to determine all possible outputs.

To test a decision table first the inputs and preconditions are listed in the left column. Then all possible combinations of inputs and preconditions are listed in the rows of the table. Finally, the expected outputs are listed in the right column.

Here is an example decision table:

Inputs/Preconditions | A | B | C | Outputs
---------------------|---|---|---|--------
True | X | | | 1
True | | X |

Decision table testing is a black-box testing technique used to test systems based on decision tables. A decision table is a tabular representation of system inputs actions and outputs. The technique can be used to test both manual and automated systems.

The test designer creates a decision table by first identifying all the possible inputs and outputs for the system under test. They then identify all the possible combinations of inputs and outputs and finally they determine the appropriate action for each combination.

Once the decision table is complete the test designer can create test cases based on the table. To do this they simply need to select a combination of inputs and outputs and determine the expected outcome. Decision table testing can be an effective way to comprehensively test a system without needing to understand its internal workings.

Decision table testing is a black-box testing technique that can be used to test all combinations of inputs and outputs for a particular decision. A decision table is a graphical representation of all the possible inputs and outputs for a given decision and can be used to test all the different combinations of inputs and outputs to ensure that the decision is made correctly in all cases.

One advantage of using decision tables for testing is that they can be used to test complex decisions that would be difficult to test using other methods. Additionally, decision tables can be used to generate test cases that cover all possible combinations of inputs and outputs which can help to identify errors that might otherwise go undetected.

To create a decision table first list all of the possible inputs and outputs for the decision under test. Then create a table with one column for each input and one row for each output and fill in the cells with the appropriate values (e.g. “1” if the
