就是这么简单(续)！使用 RestAssuredMockMvc 测试 Spring MVC Controllers(转)

接我前面一篇文章关于RestAssured测试Restful web service的， RestAssured还有一个功能，使用RestAssuredMockMvc 单元测试你的Spring MVC Controllers, 这个MockMvc 是建立在Spring MockMvc基础上的，其目的是让我们用起来更便捷。

Getting Ready

<dependency><groupId>com.jayway.restassured</groupId><artifactId>spring-mock-mvc</artifactId><version>2.4.0</version><scope>test</scope></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><scope>test</scope></dependency><!-- Optional --><dependency><groupId>org.hamcrest</groupId><artifactId>hamcrest-core</artifactId><version>1.3</version><scope>test</scope></dependency><dependency><groupId>org.hamcrest</groupId><artifactId>hamcrest-library</artifactId><version>1.3</version><scope>test</scope></dependency>

Example

下面是我们要测试的Controller

package com.wadeshop.controller;import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;@Controller
public class GreetingController {private static final String template = "Hello, %s!";@RequestMapping(value = "/greeting", method = RequestMethod.GET)@ResponseBody public Greeting greeting(@RequestParam(value="name", required=false, defaultValue="World") String name) {return new Greeting(String.format(template, name));}
}

Greeting 类如下

public class Greeting {private final String content;public String getContent() {return content;}public Greeting(String content) {this.content = content;}}

接下来就是创建Spring MVC 测试类了

package com.wadeshop.controller;import static com.jayway.restassured.module.mockmvc.RestAssuredMockMvc.given;
import static org.hamcrest.Matchers.equalTo;import org.junit.Before;
import org.junit.Test;import com.jayway.restassured.module.mockmvc.RestAssuredMockMvc;public class GreetingControllerTest {@Beforepublic void configured() {RestAssuredMockMvc.standaloneSetup(new GreetingController());}@Testpublic void test1() {given().param("name", "Johan").when().get("/greeting").then().statusCode(200).body("content", equalTo("Hello, Johan!"));}@Testpublic void test2() {given().param("name", "").when().get("/greeting").then().statusCode(200).body("content", equalTo("Hello, World!"));}}

单元测试过程无非就这些步骤：

1. 准备测试环境，上面的例子就是使用 standalone setup 初始化MockMvc, 传入被测Controller

2. 传入参数构造请求并且调用

3. 验证结果

执行结果如下

是不是很简单？

这种方式其实就是纯粹的单元测试，如果想模拟真实的Spring MVC, 走Spring MVC完整流程，比如Dispatcher servlet, 类型转换，数据绑定等等，则需要用MockMvcBuilders.webAppContextSetup(webApplicationContext).build(); 我在以后的文章中会介绍到。
