rpc服务框架——dubbo

https://cn.dubbo.apache.org/zh-cn/blog/2023/02/23/一文帮你快速了解-dubbo-核心能力/
自制项目：
https://github.com/Jinwenxin/rpc.git

1. 单元测试

import org.junit.Before;
import org.junit.Test;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

import static org.mockito.Mockito.;
import static org.junit.Assert.;

public class MyDubboServiceTest {

@InjectMocks
private MyDubboService myDubboService;

@Mock
private DependencyService dependencyService;

@Before
public void setUp() {
    MockitoAnnotations.initMocks(this);
}

@Test
public void testServiceMethod() {
    // Arrange
    when(dependencyService.someMethod()).thenReturn("Mocked Result");

// 当你这几个接口里，调用什么依赖的服务的方法，那么我们用这个句话让那个方法按照预期的返回，也就是假定依赖正常工作的情况下。

    // Act
    String result = myDubboService.serviceMethod();

    // Assert
    assertEquals("Expected Result", result);
}

}

2. 集成测试

import org.apache.dubbo.config.annotation.DubboReference;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

import static org.junit.jupiter.api.Assertions.assertEquals;

@SpringBootTest
public class MyDubboServiceIntegrationTest {

@DubboReference
private MyDubboService myDubboService;

@Test
public void testServiceMethod() {
    String result = myDubboService.serviceMethod();
    assertEquals("Expected Result", result);
}

}
怎么理解这个和集成的区别呢？就是让dubbo接口去调用真实环境的依赖，而不是像单元测试中的mock。

3. 写个APIGateway项目（consumer）去测试

另外写一个项目，写个controller，方法中去调用dubbo service的API。
跟我在其他项目中去调用该服务是一样的。
package com.jinwenxin.controller;

import org.apache.dubbo.config.annotation.DubboReference;
import org.apache.dubbo.springboot.demo.DemoService;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/anotherApi")
public class AnotherDubboController {

@DubboReference
private DemoService myDubboService;

@GetMapping("/serviceMethod/{param}")
public String callServiceMethod(@PathVariable String param) {
    return myDubboService.sayHello(param);
}

}
然后就可以在postman或者jmeter里发请求了。
