Which dependencies are required for these tests?

You need the jakarta.validation-api and a provider like hibernate-validator, along with JUnit 5 and AssertJ to implement the provided testing patterns.

How do I assert specific validation error messages?

The skill demonstrates how to use AssertJ to extract messages from ConstraintViolation sets and verify they match your expected error strings or property paths.

Can I test custom @Constraint annotations?

Yes, the skill includes specific implementation patterns for testing custom ConstraintValidator implementations and complex cross-field validation logic.

Does this support validation groups?

Yes, it provides examples for testing conditional validation using Jakarta validation groups to separate different logic for create and update operations.

Do I need Spring Boot to use this skill?

No, this skill focuses on testing validation logic in isolation using a standalone ValidatorFactory, avoiding the overhead of the Spring context for faster test execution.

安全与测试

Simplifies testing of Jakarta Bean Validation constraints and custom validators using JUnit 5 and AssertJ.

关于

This skill provides a comprehensive set of patterns and boilerplate for unit testing Jakarta Bean Validation annotations like @NotNull, @Email, and @Size, as well as complex custom and cross-field validators. By utilizing a standalone Validator instance without the overhead of a Spring context, it enables high-performance, isolated tests for data integrity rules and domain model constraints. It covers common scenarios including error message verification, validation groups, and parameterized testing for edge cases, ensuring robust data validation logic in Java applications.
