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 对@ConfigurationProperties 类进行单元测试的模式。在验证应用程序配置绑定和验证时使用。 来源：giuseppe-trisciuoglio/developer-kit。
