FakeBuilder Generator

FakeBuilder Generator creates complete, realistic test data builders for DDD aggregates using Chance.js. It generates fluent API builders with type augmentation, PropOrFactory support, and default properties you can override, outputting ready-to-use builder files with explanatory comments.

A FakeBuilder is a fluent API that generates realistic test data for aggregates with sensible defaults and factory support. It eliminates boilerplate test fixture creation, ensures consistent fake data across tests, and keeps test setup readable and maintainable.

Yes. FakeBuilder Generator integrates Chance.js with PropOrFactory<T> support, allowing each property to accept either a fixed value or a factory function, giving you fine-grained control over test data generation while maintaining type safety.

FakeBuilder Generator creates builders with sensible Chance.js-generated defaults for all properties. During test setup, you override specific properties with fixed values or factories as needed, keeping most defaults intact while customizing only what matters for each test case.

The generator outputs a typed FakeBuilder file to [module]/domain/[name].fake-builder.ts with static factory methods, fluent API chains, and inline comments explaining property generation logic and usage patterns.

Yes. FakeBuilder Generator creates builders for both unit and integration test scenarios, generating realistic aggregate data with domain-appropriate values and factory support, making test fixtures maintainable across different test scales.
