unit-test-config-properties

This skill provides patterns for unit testing @ConfigurationProperties bindings, environment-specific configurations, and property validation using JUnit 5. It covers testing property name mapping, type conversions, validation constraints, nested structures, and profile-specific configurations without full Spring context startup.

Properties not binding: Verify prefix and property names match exactly (including kebab-case to camelCase conversion).

Validation not triggered: Ensure @Validated is present and validation dependencies are on classpath.

提供使用@ConfigurationPropertiesTest 對@ConfigurationProperties 類別進行單元測試的模式。在驗證應用程式配置綁定和驗證時使用。 來源：giuseppe-trisciuoglio/developer-kit。
