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 是創建在Spring MockMvc基礎上的, 其目的是讓咱們用起來更便捷。web

 

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

下面是咱們要測試的Controllerspring

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 以下mvc

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 測試類了單元測試

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:測試

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Controllerui

2. 傳入參數構造請求而且調用this

3. 驗證結果google

 

執行結果以下

 

是否是很簡單?

 

這種方式其實就是純粹的單元測試,若是想模擬真實的Spring MVC, 走Spring MVC完整流程,好比Dispatcher servlet, 類型轉換,數據綁定等等, 則須要用MockMvcBuilders.webAppContextSetup(webApplicationContext).build(); 我在之後的文章中會介紹到。
