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。
