接我前面一篇文章關於RestAssured測試Restful web service的， RestAssured還有一個功能， 使用RestAssuredMockMvc 單元測試你的Spring MVC Controllers, 這個MockMvc 是建立在Spring MockMvc基礎上的， 其目的是讓我們用起來更便捷。

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

下面是我們要測試的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 類 如下

public class Greeting {

    private final String content;

    public String getContent() {

        return content;

    }

    public Greeting(String content) {

        this.content = content;

    }

}

接下來就是建立Spring MVC 測試類了

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!"));

    }

}

單元測試過程無非就這些步驟：

1. 準備測試環境， 上面的例子就是使用 standalone setup 初始化MockMvc, 傳入被測Controller

2. 傳入引數構造請求並且呼叫

3. 驗證結果

執行結果如下

是不是很簡單？

這種方式其實就是純粹的單元測試，如果想模擬真實的Spring MVC, 走Spring MVC完整流程，比如Dispatcher servlet, 型別轉換，資料繫結等等， 則需要用MockMvcBuilders.webAppContextSetup(webApplicationContext).build(); 我在以後的文章中會介紹到。
