如何使用WebFlux和Java8进行下面的代码单元测试？

<dependencies>
    <!-- WebFlux -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-webflux</artifactId>
    </dependency>
    <!-- JUnit -->
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-api</artifactId>
        <scope>test</scope>
    </dependency>
    <!-- 其他依赖 -->
</dependencies>

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.reactive.WebFluxTest;
import org.springframework.test.web.reactive.server.WebTestClient;

@WebFluxTest(MyController.class)
public class MyControllerTest {

    @Autowired
    private WebTestClient webClient;

    @Test
    public void testMyMethod() {
        webClient.get().uri("/my-endpoint")
                .exchange()
                .expectStatus().isOk()
                .expectBody(String.class).isEqualTo("Expected response");
    }
}
