@ParameterizedTest with @MethodSource are not supported.

[michael-simons]

A parameterized tests with an @MethodSource like this

import java.util.stream.Stream;

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.Arguments;
import org.junit.jupiter.params.provider.MethodSource;

class App2Test {

	enum Things {
		A, B, C
	}

	@ParameterizedTest
	@MethodSource("aMethod")
	void functionNameSanityCheck(Things thing) {

		Assertions.assertNotNull(thing);
	}

	private static Stream<Arguments> aMethod() {
		return Stream.of(
			Arguments.of(Things.A),
			Arguments.of(Things.B),
			Arguments.of(Things.C)
		);
	}
}

fails with
