## 概述 ##

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

主要是通过 @RunWith 和 @SpringBootTest 注解来开启单元测试功能

package com.yuu.hello.spring.boot;
    
    import org.junit.Before;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    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.boot.web.server.LocalServerPort;
    import org.springframework.http.ResponseEntity;
    import org.springframework.test.context.junit4.SpringRunner;
    
    import java.net.MalformedURLException;
    import java.net.URL;
    
    import static org.hamcrest.CoreMatchers.equalTo;
    import static org.junit.Assert.assertThat;
    
    @RunWith(SpringRunner.class)
    @SpringBootTest(classes = HelloSpringBootApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
    public class HelloSpringBootApplicationTests {
    
        @LocalServerPort
        private int port;
    
        private URL base;
    
        @Autowired
        private TestRestTemplate template;
    
        @Before
        public void setUp() throws MalformedURLException {
            this.base = new URL("http://localhost:" + port + "/");
        }
    
        @Test
        public void contextLoads() {
            ResponseEntity<String> response = template.getForEntity(base.toString(), String.class);
            assertThat(response.getBody(), equalTo("Hello Spring Boot"));
        }
    
    }

运行它会先启动 Spring Boot 工程，再启动单元测试
