Released on September 26, 2024, consistgen v0.0.4 is a maintenance update focused on enhancing the developer experience by bringing the library’s API into closer alignment. This release streamlines how you handle predictable data in your tests, ensuring that the tools you use to eliminate randomness are themselves consistent and intuitive.

What’s new

The centerpiece of this release is the modernization of the SettableUuidGenerator. To match the design patterns used across the rest of the library, we have transitioned from standard constructors to a robust builder pattern.

In addition to the new instantiation method, the SettableUuidGenerator now features a sensible default. If a generator is initialized without a specific UUID, or if a null value is provided, it now automatically defaults to a zero-filled UUID (00000000-0000-0000-0000-000000000000), preventing unexpected null pointer exceptions in your test suites.

Why it matters

Consistency isn’t just what consistgen provides for your data—it’s how the library feels to use. By implementing the builder pattern for SettableUuidGenerator, we’ve reduced the cognitive load for developers. You no longer need to remember which constructor to use; the builder provides a clear, fluent API for configuration.

The introduction of a default UUID further strengthens the reliability of your tests, ensuring that your environment remains stable even when specific identifiers aren’t explicitly provided.

Upgrade and Installation

To upgrade to v0.0.4, update your Maven dependency:

<dependency>
    <groupId>com.unitvectory</groupId>
    <artifactId>consistgen</artifactId>
    <version>0.0.4</version>
</dependency>

Note on Breaking Changes: Because we have replaced the constructors in SettableUuidGenerator with a builder, direct instantiation via new SettableUuidGenerator() will no longer work. Please migrate your code to use the builder:

  • Old: new SettableUuidGenerator(uuid)
  • New: SettableUuidGenerator.builder().uuid(uuid).build()

For a default generator, use SettableUuidGenerator.builder().build().
