Instancio

Generates complete object graphs, including nested objects and collections, with a single line like `Instancio.create(Person.class)`, drastically reducing boilerplate code in test setup.

Ensures random data can be reproduced for debugging test failures, making tests reliable and maintainable without manual data tracking.

Provides `InstancioExtension` for injecting generated arguments into test methods and parameterized tests, streamlining test execution as shown with `@Given` annotations and `@InstancioSource`.

Supports generics, records, sealed classes, and Java 21 sequenced collections, keeping up with language advancements for contemporary projects.

Allows fine-grained control via generators, templates, and data feeds, as demonstrated with custom value generation for dates, patterns, and reusable models like the Simpsons example.
