Class ParameterizedTestSupport

  • public final class ParameterizedTestSupport
extends java.lang.Object
    Utility class for managing JUnit Jupiter Params dependency availability at runtime. This enables graceful degradation when parametrized test support is not available. Provides safe class loading and caching for all JUnit params annotations and classes.
