Use Lombok builders in test data factory

[nathancrtr]

A number of the test data factory methods do not accept arguments that can be passed into the constructor. If a developer wants to run assertions against a non-configurable property, they must add a new method to the library that accepts the desired parameter and creates an instance with that value.

Investigate using Lombok builders to invert this pattern so that we can have more granular control over the test fixtures we are producing.

Would also want to update the backend tests to match this new pattern.
