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

@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 Exception {
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
