Unit Test Your Java Architecture With ArchUnit by Roland Weisleder

Unit test your Java architecture with ArchUnit, a tool that ensures your code aligns with defined rules and constraints, providing feedback on violations and facilitating continuous integration and refactoring.

Key takeaways
  • ArcUnit can be used to unit test Java architecture, ensuring it matches the defined rules and constraints.
  • Developers often struggle to maintain architecture integrity, especially in legacy projects, due to changes and refactoring.
  • ArcUnit provides a fluent API for defining architecture rules and constraints, making it easy to use in new projects or integrate into existing ones.
  • The tool analyzes Java byte codes and provides feedback on architecture violations, allowing developers to resolve issues before introducing new code.
  • ArcUnit can check dependencies between classes, packages, and layers, ensuring they align with the defined architecture.
  • It also provides a freezing mechanism, which helps to maintain architecture integrity by analyzing code against a frozen version of the architecture.
  • The tool can be used to define custom architecture rules and constraints using a fluent API.
  • ArcUnit can be integrated with JUnit 5 for automated testing and continuous integration.
  • It provides rich error messages, making it easy to identify and resolve architecture violations.
  • ArcUnit can be used to define and enforce architecture rules for layered architecture, domain-driven design, and other architectural patterns.
  • The tool is easy to use and provides a lot of flexibility, making it suitable for a wide range of projects and use cases.
