What

to create input data or objects for unit tests

Facilitate writing tests by allowing easy creation of inputs or expected data.
Facilitate test maintainability by decoupling the creation of objects in tests, and isolating it in a single location (Single Responsibility Principle)
Disseminate functional understanding in the team through the use of business terms
Facilitate the readability of the tests by explaining only the data implied in the use case
