Spring Boot(七)：spring boot測試介紹

Spring Boot

首先maven要引入spring-boot-starter-test這個包。

先看一段程式碼

@RunWith(SpringRunner.class)

@SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT)

public class MyTest {

        @Autowired

    private TestRestTemplate restTemplate;

    @Test 

  public void test() {

        this.restTemplate.getForEntity( 

           "/{username}/vehicle", String.class, "Phil");

    }

}

1、@RunWith(SpringRunner.class) 告訴JUnit執行使用Spring的測試支援。SpringRunner是SpringJUnit4ClassRunner的新名字，這個名字只是讓名字看起來簡單些。

2、@SpringBootTest的意思是“帶有Spring Boot支援的載入程式”（例如，載入應用程式、屬性，為我們提供Spring Boot的所有精華部分）。

3、webEnvironment屬性允許為測試配置特定的“網路環境”。你可以利用一個MOCK小服務程式環境開始你的測試，或者使用一個執行在RANDOM_PORT 或者 DEFINED_PORT上的真正的HTTP伺服器。

4、如果我們想要載入一個特定的配置，我們可以用@SpringBootTest class屬性。在這個例項中，我們省略classes就意味著測試要首次嘗試從任意一個inner-classes中載入@ configuration，如果這個嘗試失敗了，它會在你主要的@SpringBootApplicationclass中進行搜尋。

 ------------------------------------------------------------------------------------------------------------------------------

其中IndexController是你寫的controller

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class IndexTest {


    private MockMvc mvc;

    @Autowired
    private IndexController indexController;


    @Before
    public void setup() {
        this.mvc = MockMvcBuilders.standaloneSetup(indexController).build();
    }

    @Test
    public void t() throws Exception {
        assertNotNull(mvc);

        mvc.perform(MockMvcRequestBuilders.get("/h").
                accept(MediaType.parseMediaType("application/json;charset=UTF-8")))
                .andExpect(MockMvcResultMatchers.status().isOk());
        
    }
}

這個是第二種測試方法：

package com.hexun.bdc.auth.controller;

import com.hexun.bdc.auth.client.Application;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.embedded.LocalServerPort;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.web.client.TestRestTemplate;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;

import static org.assertj.core.api.Assertions.assertThat;
import static org.junit.Assert.assertNotNull;

/**
 * Created by iceblue on 2017/3/26.
webEnvironment=RANDOM_PORT表示啟動服務時埠隨機（避免埠衝突）
 */

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, classes = Application.class)
@AutoConfigureMockMvc
public class IndexControllerTest {

    @Autowired
    protected MockMvc mvc;

    @LocalServerPort // 注入埠
    private Integer port;

    @Autowired
    private TestRestTemplate restTemplate;

    private static final Logger logger = LoggerFactory.getLogger(IndexControllerTest.class);

    @Test
    public void t() throws Exception {
        assertNotNull(mvc);

        logger.info("# port:" + port.toString());

        assertThat(this.restTemplate.getForObject("http://localhost:" + port + "/h",
                String.class)).contains("hello");
//        mvc.perform(MockMvcRequestBuilders.get("/h"))
//                .andExpect(MockMvcResultMatchers.status().isOk());
    }

}

是第三種測試方法，直接利用TestRestTemplate類

package com.hexun.bdc.auth.controller;

import com.hexun.bdc.auth.client.Application;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.web.client.TestRestTemplate;
import org.springframework.test.context.junit4.SpringRunner;

import static org.junit.Assert.assertNotNull;


@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,classes = Application.class)
public class IndexTest2 {


    @Autowired
    private TestRestTemplate restTemplate;
    private static final Logger logger = LoggerFactory.getLogger(IndexTest2.class);


    @Test
    public void t() throws Exception {
        assertNotNull(restTemplate);
        String body = this.restTemplate.getForObject("/h", String.class);
        System.out.println("body = " + body);
        logger.info("body = " + body);

    }

}
