## Spring Cloud Contract契约测试 ##

> 单元测试、组件测试和集成测试的一个共同特点是，会将应用的某一部分隔离开来去测试，而不是测试整个完整的应用。对于单元测试，被测单元只有一个或者很少几个类 ；对于集成测试，你在应用的边界测试应用是否可以连接到一个真实的服务。在微服务架构下，你的服务可能由不同的团队提供和维护，在这种情况下，接口的开发和维护可能会带来一些问题，比如服务端调整架构或接口调整而对消费者不透明，导致接口调用失败。为解决这些问题，Ian Robinson提出了一个以服务消费者定义契约为驱动的开发模式：“Consumer-Driver Contracts(CDC)”，就是：消费者驱动契约

> 消费者驱动的契约测试（Consumer-Driven Contracts，简称CDC），是指从消费者业务实现的角度出发，驱动出契约，再基于契约，对提供者验证的一种测试方式。

这里就假设有provider团队和consumer团队。那么当provider团队的服务还没有开发好，或者provider的团队的服务没有在启动的时候，我们可不可以进行开发呢？

答案是可以的。

### 契约（Contract） ###

> 这里就假设有provider团队和consumer团队。那么当provider团队的服务还没有开发好，或者provider的团队的服务没有在启动的时候，我们可不可以进行开发呢？ ->可以的。

> 这里引入一个重要的概念，就是契约，Contract。这是什么呢？很简单，就是provider和consumer事先要约定好一个接口的规范，之后双方提供服务接口和消费服务接口都要按照这个契约来。

> Spring Cloud Contract 提供不错的实现，它分为验证服务（Verifier）和对契约内容Mock服务（Stub Runner）两部分。

> 契约使用步骤可大致分为：
> 
> 1.  生产者提供定义好的契约(接口，包含request Method、header,parameter,body)
> 2.  生产者生成stub jar,提供给消费者,可mvn install到Maven库(本地/远程仓库)
> 3.  消费者调用生产者的接口(从契约获取数据)

### 生产者(服务提供方)提供定义好的契约 ###

现在我们开始编写我们的契约测试，首先我们来处理生产者这一方。

1.  首先我们先添加依赖还有插件。我们的生产者也就是服务的提供方是order服务，所以我们需要在cloud-service-order服务下添加依赖和插件。

<dependency>
        
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-contract-verifier</artifactId>
        <scope>test</scope>
    </dependency>

<build>
        <plugins>
            <plugin>
                
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-contract-maven-plugin</artifactId>
                
                
                <version>2.0.2.RELEASE</version>
                <extensions>true</extensions>
                <configuration>
                    <baseClassForTests>com.cc.cloud.contract.OrderBase</baseClassForTests>
                </configuration>
            </plugin>
        </plugins>
    </build>

1.  创建插件指定的测试基类OrderBase

路径：`src\test\java\com\cc\cloud\contract\OrderBase.java`

package com.cc.cloud.contract;
    
    import com.cc.cloud.order.controller.OrderController;
    import io.restassured.module.mockmvc.RestAssuredMockMvc;
    import org.junit.Before;
    
    public class OrderBase { 
    
        @Before
        public void setup() { 
            RestAssuredMockMvc.standaloneSetup(new OrderController());
        }
    }

OrderController如下：

package com.cc.cloud.order.controller;
    
    import com.cc.cloud.order.feign.MemberFeign;
    import com.google.common.collect.Lists;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.cloud.context.config.annotation.RefreshScope;
    import org.springframework.http.HttpStatus;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseStatus;
    import org.springframework.web.bind.annotation.RestController;
    
    import java.util.List;
    
    @RefreshScope
    @RestController
    @RequestMapping("/order")
    public class OrderController { 
    
        private final Logger logger = LoggerFactory.getLogger(OrderController.class);
    
        private MemberFeign memberFeign;
    
        @Value("${cloud.service.order}")
        private String orderConfig;
    
        @Autowired
        public void setMemberFeign(MemberFeign memberFeign) { 
            this.memberFeign = memberFeign;
        }
    
        @RequestMapping("/members")
        @ResponseStatus(HttpStatus.OK)
        public List<String> getMemberList() { 
            return memberFeign.getAllMemberList();
        }
    
    
        @GetMapping("/orders")
        @ResponseStatus(HttpStatus.OK)
        public List<String> getOrders() { 
            List<String> orders = Lists.newArrayList();
            orders.add("order 1");
            orders.add("order 2");
            return orders;
        }
    
        @GetMapping("/config")
        @ResponseStatus(HttpStatus.OK)
        public String getOrderConfig(){ 
            return orderConfig;
        }
    }

1.  编写契约

增加契约文件，可以有多种格式如groovy 、yaml，这里采用yaml。

契约默认位置：`src/test/resources/contracts`

路径: `src\test\resources\contracts\should_return_order_list.yml`

request:
      method: GET
      url: /order/orders
    response:
      status: 200
      headers:
        Content-Type: application/json;charset=UTF-8
      body:
        ["order 1","order 2"]

1.  服务提供方进行契约测试并生成stubs-jar

mvn clean install

当然也可以用Maven插件工具去生成。

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nja2V2aW5jeWg_size_16_color_FFFFFF_t_70]

当然如果服务提供方没有完成接口的开发，可以用下面的命令去提供stubs-jar

mvn clean install -DskipTests

存根jar已安装到本地Maven仓库，可提供给其他服务调用,后面会调用到。

### 消费者(服务调用方)使用存根 ###

1.  这里的服务调用方式member服务，所以我们需要在cloud-service-member中添加依赖

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-contract-stub-runner</artifactId>
        <scope>test</scope>
    </dependency>

1.  编写测试类

package com.cc.cloud.member.controller;
    
    import com.cc.cloud.test.common.ControllerTestBase;
    import org.junit.Test;
    import org.springframework.cloud.contract.stubrunner.spring.AutoConfigureStubRunner;
    import org.springframework.cloud.contract.stubrunner.spring.StubRunnerProperties;
    import org.springframework.http.MediaType;
    
    import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
    import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
    //@AutoConfigureStubRunner自动下载存根
    @AutoConfigureStubRunner(ids = { "com.cc.cloud:cloud-service-order:+:stubs:8095"}, stubsMode = StubRunnerProperties.StubsMode.LOCAL)
    public class MemberControllerContractTest extends ControllerTestBase { 
    
        @Test
        public void should_return_status_isOk_when_call_api_members_given_get_method() throws Exception { 
            this.getMockMvc()
                    .perform(
                            get("/member/orders")
                                    .contentType(MediaType.APPLICATION_JSON)).andExpect(status().isOk());
        }
    }

1.  运行测试

契约测试的流程就已经完成了。
