Spring boot 使用单元测试

1.pom.xml新增依赖

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-test</artifactId>
			<version>2.2.4.RELEASE</version>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<version>2.2.4.RELEASE</version>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>4.12</version>
			<scope>test</scope>
		</dependency>

2.新建测试方法

包名需和实际方法的包名保持一致

@RunWith(value = SpringRunner.class)
@SpringBootTest(classes = App.class)//App.class为实际代码启动类，
//@SpringBootTest(classes = App.class, webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
//如果项目使用了websocket，需要加上webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT，否则会报错
public class AppTest {
    @Test
    public void test() {

    }
}
