Pattern summary

Use default data to simplify data input

Category

Design

Context

This pattern is useful when test cases need a lot of common data that is not all meaningful for the specific test.

Description

Instead of cluttering test cases with data that is needed, but is not relevant for the specific test, use default data.

For example, if you are interested in testing validation for a Name field but don't care about the contents of the address or phone number fields, set up a default value for the address ("123 Main Street") and phone number. Then in your test, you will say what the Name field should contain, but not what the other fields should contain, so your framework will copy the default values (because if they were left blank, the test would fail) to those fields.

Implementation

Prepare default data. Your TEST AUTOMATION FRAMEWORK substitutes default data for missing data during the data inputs in the test cases

Potential problems

Default values should be valid, but there may be combinations of other values that make a normally valid value invalid.
You may end up with a lot of people living at the same address… ;-)
