Test case design technique.

What is Software Testing Technique?

Software Testing Techniques help you design better test cases. Since exhaustive testing is not possible; Manual Testing Techniques help reduce the number of test cases to be executed while increasing test coverage.

The different types of test case design techniques are

• Boundary Value Analysis (BVA)
• Equivalence Class Partitioning
• Decision Table based testing.
• State Transition
• Error Guessing

Decision Table Based Testing.

A decision table is also known as to Cause-Effect table. This software testing technique is used for functions which respond to a combination of inputs or events.

The first we should identify functionalities where the output depends on a combination of inputs.

For every function, you need to create a table and list down all types of combinations of inputs and its respective outputs. This helps to identify a condition that is overlooked by the tester.

Following are steps to create a decision table:

• Enlist the inputs in rows
• Enter all the rules in the column
• Fill the table with the different combination of inputs
• In the last row, note down the output against the input combination.

Example: A submit button in a contact form is enabled only when all the inputs are entered by the end user.
