SpringBoot测试类启动web环境-上篇

1.坐标修改

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

2.测试类测试

说明：@SpringBootTest()中的webEnvironment值的说明；

2.1不启动

说明：默认不启动，如下图所示。@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.NONE)。

package com.forever;

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.NONE)
public class WebTest {
    @Test
    void test(){

    }

}

2.2默认端口

说明：@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)

package com.forever;

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
public class WebTest {
    @Test
    void test(){

    }

}

2.3 随机端口

说明：随机端口，@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)。

package com.forever;

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class WebTest {
    @Test
    void test(){

    }

}

3.发送虚拟请求

3.1@AutoConfigureMockMvc

说明：开启虚拟mvc调用。

package com.forever;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.RequestBuilder;
import org.springframework.test.web.servlet.request.MockHttpServletRequestBuilder;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
//开启虚拟mvc调用
@AutoConfigureMockMvc
public class WebTest {

    @Test
    //形参写入或者上方写@Autowired；为方法注入资源。
    void testWeb(@Autowired MockMvc mockMvc) throws Exception {
        //发请求http://....../users；下面就是模拟的一个http请求，访问的是users
        MockHttpServletRequestBuilder builder= MockMvcRequestBuilders.get("/users");
        //执行对应的请求。
        mockMvc.perform(builder);

    }


}
