java单元测试

idea 安装插件TestMe, 进入具体的类，选中类名 右键

1.多线程测试用例

@Mock Executor taskExecutor;

或者

@Mock ThreadPoolExecutor threadPoolExecutor;

都可用如下方法：

doAnswer((InvocationOnMock invocation) -> {

((Runnable) invocation.getArguments()[0]).run();

return null;

}).when(taskExecutor).execute(any(Runnable.class));

@Mock ScheduledThreadPoolExecutor executor;

executor.schedule(()->{

........

},10, TimeUnit.MINUTES);

doAnswer(invocation -> {

((Runnable) invocation.getArguments()[0]).run();

return null;

}).when(executor).schedule(any(Runnable.class),anyLong(), any());

@InjectMocks Test test;

@BeforeEach

void setUp() {

test = new test(a);//避免抢占资源，每次创建

}

@AfterEach

void after() {

test = null;//每次销毁

}

2.ReflectionTestUtils.setField() 用法：

@InjectMocks

TestService testService; //当前的测试类

1).这种注入方式

@Value("${test.active.switch:0}")

private String activeSwitch;

测试用例写法：

ReflectionTestUtils.
