1、sprinboot中直接写测试用例

1.1、如果直接输入@Test就会自动让我将这个版本放到pom中去

WX20190131-132859

1.1.1、然后pom.xml中就出现了下面的

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <version>RELEASE</version>
    <scope>compile</scope>
</dependency>

1.1.2、如果运行报下面错误

主要是上面的依赖导致的错误

Exception in thread "main" java.lang.NoSuchMethodError: org.junit.platform.commons.util.ReflectionUtils.getDefaultClassLoader()Ljava/lang/ClassLoader;
    at org.junit.platform.launcher.core.ServiceLoaderTestEngineRegistry.loadTestEngines(ServiceLoaderTestEngineRegistry.java:30)
    at org.junit.platform.launcher.core.LauncherFactory.create(LauncherFactory.java:53)
    at com.intellij.junit5.JUnit5IdeaTestRunner.createListeners(JUnit5IdeaTestRunner.java:39)
    at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:49)
    at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242)
    at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70)

1.2、使用新的依赖


<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
</dependency>

2、SpringBoot真正测试

2.1、maven

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>org.junit.vintage</groupId>
            <artifactId>junit-vintage-engine</artifactId>
        </exclusion>
    </exclusions>
</dependency>

2.2、开始测试

@Slf4j
@RunWith(SpringRunner.class)
@SpringBootTest(classes = AppApplication.class)
public class MainTest {

    @Autowired
    private CacheService cacheService ;

    @Test
    public void test(){
        while (true){
            boolean lock = cacheService.lock("TEST", 1, TimeUnit.MINUTES);
            if (lock){
                log.info("锁状态【{}】", lock);
            }
        }
    }

}

3、单元测试可以暂停、继续(通过键盘控制)

3.1、idea配置（记得重启idea）

加上： -Deditable.java.test.console=true

3.2、测试

@Slf4j
@SpringBootTest(classes = StartApp.class)
@RunWith(SpringRunner.class)
public class BatteryInfoTest {


  @Autowired
  private CacheService cacheService ;


  @Test
  public void testSelect() {
    before();

    boolean lock = cacheService.lock("TEST", 1, TimeUnit.MINUTES);
    if (lock){
      log.info("锁状态【{}】", lock);
    }

    //继续调用
    testSelect();
  }
  
  
  

  public void before(){
    Scanner scanner = new Scanner(System.in);
    System.out.println("=========请输入任意内容即可继续=======================");
    scanner.nextLine();
  }
}
