unit-test-bean-validation

What problem does it solve?

This Skill streamlines the process of testing data validation logic in Java applications, ensuring that constraints and custom validators work as expected without needing a full Spring context.

Core Features & Use Cases

• Validate Annotations: Test standard Jakarta Bean Validation annotations like @NotNull, @Email, @Min, @Max, and @Size.
• Test Custom Validators: Verify the correctness of custom constraint annotations and their validator implementations.
• Cross-Field Validation: Ensure validation logic that spans multiple fields is correctly applied.
• Validation Groups: Test conditional validation rules based on different validation groups.
• Use Case: You've implemented complex validation rules for user registration forms, including custom checks for password strength and phone number formats. Use this Skill to write isolated, fast unit tests for all these validation rules before integrating them into your application.

Quick Start

Use the unit-test-bean-validation skill to test if a User object with a null name triggers a 'must not be blank' validation error.
