java - Spring 反应式测试用例

问题描述

我一直在尝试为 Spring Reactive 模块编写单元测试用例。我在该模块中遇到错误。

这是我的测试用例代码：

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.reactive.AutoConfigureWebTestClient;
import org.springframework.boot.test.autoconfigure.web.reactive.WebFluxTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.reactive.server.WebTestClient;


@RunWith(SpringRunner.class)
@WebFluxTest(CustomController.class)
@AutoConfigureWebTestClient
public class CustomControllerTest {

    @Autowired
    private WebTestClient testClient;

    @Test
    public void broadcastVoltageConsumption() {
        System.out.println("CONTEXT LOADING >>>>>>>>>");
        System.out.println(testClient);
    }
}

我收到以下错误：

java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

虽然另一个具有 main 方法的类具有相同的配置，但它可以正常工作。

@RunWith(SpringRunner.class)
@WebFluxTest
public class SpringWebFluxDemoApplicationTests {

    @Test
    public void contextLoads() {
        System.out.println("CONTEXT LOAD ########## ");
    }

}

无法弄清楚这里出了什么问题，对此有什么帮助吗？
