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 {
@Before
public void configured() {
RestAssuredMockMvc.standaloneSetup(new GreetingController());
}
@Test
public void test1() {
given().
param("name", "Johan").
when().
get("/greeting").
then().
statusCode(200).
body("content", equalTo("Hello, Johan!"));
}
@Test
public 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。
