Overview

A high level way to generate a list of generated values that fit a specific format, such as an ID, postal code, or phone number.

It provides generators for random digits and letters, hardcoded literal strings, computed values based on previously-generated values, union (one-of) selectors, and grouped generators.

The generation allows for dependencies on previously generated values – most useful for computations – and this object knows how to build that dependency graph.

See Builder for more.
