Unit Test Bean Validation

What it does

This skill enables AI agents to generate and execute unit tests for Java Bean Validation constraints, ensuring that data models adhere to defined validation rules. It helps verify that annotations like @NotNull, @Size, or @Pattern are correctly applied and functioning as intended.

When to use it

• You need to validate the correctness of Java Bean Validation logic in your application.
• You're developing a new data model with constraints and want to ensure they’re properly tested.
• You're refactoring existing code that uses Bean Validation and want to maintain test coverage.

Key capabilities

• Generates unit tests for Java classes annotated with validation constraints.
• Executes tests to confirm that validation rules are enforced correctly.
• Integrates with testing frameworks like JUnit or TestNG.

Example prompts

• "Generate unit tests for the User class using Bean Validation annotations."
• "Test if the @Email constraint on the email field of the Profile class works as expected."
• "Write and run a test case to validate that the @Min(18) constraint on the age field is enforced."

Tips & gotchas

• Ensure your project includes necessary dependencies like Hibernate Validator for Bean Validation support.
• This skill assumes familiarity with Java and unit testing frameworks; consider providing context if tests fail unexpectedly.
