FAQ

Which module should I use?

Use krandom-core for generation APIs. Add krandom-jackson for Jackson serialization support, krandom-junit for the JUnit seed extension, krandom-spring-boot-starter for Spring Boot, krandom-kotest-extensions for Kotest adapters, or krandom-kotlin-dsl for Kotlin fixture rules. Import krandom-bom:2.10.0 to align multiple kRandom modules.

How do I keep generated data stable between test runs?

Build and reuse a seeded configuration, for example GeneratorConfig.builder().seed(42L).build().

How do I apply locale consistently?

Build one GeneratorConfig with locale(...) and pass it to all locale-aware generators in the fixture pipeline.

How do I generate structured records?

Use Field to bind provider names and Schema to generate single records or batches.

How do I extend providers dynamically?

Use an explicitly installed, configuration-scoped KRandomModule when the same contribution must work through provider lookup, schemas, safety metadata, and semantic object fields. Use ProviderHub.register(...) only for a short-lived hub-local provider.

Can Kotlin or Scala consume the library?

Yes. Kotlin and Scala can use the Java krandom-core artifact directly. Kotlin projects can also use krandom-kotlin-dsl for typed fixture rules, while Kotest projects can use krandom-kotest-extensions for property-testing adapters. See Kotlin DSL and Property Testing Integrations.
