Grails projects often suffer from regressions and unclear design. TDD enforces tests before code, ensuring early validation and documentation of intended behavior.
Begin by writing a failing domain test, then implement code to pass, and refactor.

To implement Grails features with TDD, write a failing Spock test first, then write the minimum code to pass it, and finally refactor. This Red-Green-Refactor cycle drives design from domain models to controllers.
TDD in Grails supports unit tests, integration tests, and controller tests using the Spock framework. These tests guide progression from domain models to controllers during feature development and refactoring.
Using TDD for Grails applications prevents regressions and clarifies software design. Writing tests before code ensures early validation and documents the intended behavior of your domain models and controllers.
You can apply TDD to bug fixing and refactoring in Grails, not just new feature development. Writing Spock tests first helps safely validate behavior changes and prevent future regressions during code updates.
The best way to start is by writing a failing domain test using Spock. Once the test fails, implement the necessary Grails domain code to pass the test, then refactor the implementation for clarity.
Grails TDD relies on Spock for unit, integration, and controller tests. The metadata does not indicate additional testing frameworks are required to drive the Red-Green-Refactor cycle across Grails features.
