Does this skill support Mockito for external dependencies?

Yes, while it prioritizes testing pure functions, it includes patterns for using Mockito when utility methods require external dependencies like a Clock or specific configuration.

How does it handle edge cases like null or empty values?

The skill explicitly includes steps and examples for testing null-safe utility methods, empty strings, and boundary values for numeric calculations.

Can I use this for testing Spring Boot applications?

Absolutely. It uses standard JUnit 5 and AssertJ, which are the primary testing libraries used in modern Spring Boot development.

Does it support parameterized tests?

Yes, it provides specific examples for using @ParameterizedTest with @ValueSource and @CsvSource to test multiple input-output scenarios in a single method.

セキュリティとテスト

Generates robust JUnit 5 test suites for Java utility classes and static methods using AssertJ assertions and edge-case validation.

This skill provides a standardized framework for testing pure functions and helper logic within Java applications. It streamlines the creation of JUnit 5 test classes, focusing on high-coverage patterns for string manipulation, mathematical calculations, collection operations, and data validation. By implementing AssertJ for fluent assertions and providing templates for parameterized testing, the skill helps developers verify foundational logic, handle boundary conditions, and ensure null-safety without the complexity of unnecessary mocking.
