Provides patterns for unit testing Jakarta Bean Validation (JSR-380), including @Valid, @NotNull, @Min, @Max, @Email constraints with Hibernate Validator. Generates custom validator tests, constraint violation assertions, validation groups, and parameterized validation tests. Validates data integrity logic without Spring context. Use when writing validation tests, bean validation tests, or testing custom constraint validators.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Unit Testing Jakarta Bean Validation ## Overview This skill provides executable patterns for unit testing Jakarta Bean Validation annotations and custom validators using JUnit 5. Covers built-in constraints (`@NotNull`, `@Email`, `@Min`, `@Max`, `@Size`), custom `@Constraint` implementations, cross-field validation, and validation groups. Tests run in isolation without Spring context. ## When to Use - Writing unit tests for Jakarta Bean Validation or JSR-380 constraints - Testing custom `@Constraint` validators and constraint violation messages - Testing bean validation logic in DTOs and request objects - Verifying cross-field validation (e.g., password matching) - Testing conditional validation with validation groups - Fast validation tests without Spring Boot context ## Instructions 1. **Add dependencies**: Include `jakarta.validation-api` and `hibernate-validator` in test scope 2. **Create base test class**: Build `Validator` once in `@BeforeEach` using `Validation.buildDefaultValidatorFactory()` 3. **Test valid cases first**: Verify objects pass without violations 4. **Test invalid cases**: Assert constraint violations include correct property path and message …

How to install
mdr add giuseppe-trisciuoglio/developer-kit/unit-test-bean-validation@sha256:d8bdf8eb1de5b49fThe line at the top of this page pins the label git:20260324.a02e282, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
