在之前的案例中,通过Mockito.when().thenReturn的方式构造了测试桩,来控制StockService.getPrice()这个方法的返回值。...when(stockService.getPrice(teslaStock)).thenReturn(500.00) 那么,如果是想多次调用getPrice()方法,会怎样呢?...(stockService.getPrice(teslaStock)) .thenReturn(500.00).thenReturn(0.0); when(stockService.getPrice...(amazonStock)) .thenReturn(1000.00).thenReturn(0.0).thenReturn(1.0);; assertThat(portfolio.getMarketValue...当没有指定调用次数的返回值时,Mockito会返回最后一次thenReturn的值。
Mockito作为一款不错的单元测试mock工具,极大的提升单元测试效率,但是在使用该工具时需要注意Mockito打桩的方法参数一定不能是基础类型(boolean、int),否则使用any()的时候就会报空指针异常...: int save(DeviceType deviceType, boolean isCreate) --错误命名 Mockito.when(deviceTypeManager.save(any(),...any())).thenReturn(mockDevType); int save(DeviceType deviceType, Boolean isCreate) --正确命名
添加关注 刚使用Mockito来做Java项目的单元测试时,对doAnswer…when的使用场合不怎么理解,查了Mockito的官方文档和网上的各种资料,感觉都说得不够清楚。...原来,doAnswer…when和when…thenReturn的功能类似,都是用于给模拟对象指定调用其方法后的返回值,只不过二者有如下区别: 01 when…thenReturn: 当我们为模拟对象指定调用其方法的返回值时..., when…thenReturn用于直接返回一个简单的值。...下面通过代码来看它们的使用场合, 首先是使用when…thenReturn的代码: @Mock private SecurityBean testSecurity; ......Mockito.when(testSecurity.getSecurityId()).thenReturn("testSecurityId"); ... } catch

:定义模拟行为的艺术基础用法when().thenReturn()是Mockito的核心语法,用来定义模拟对象的行为:```java// 简单返回值when(userRepository.findById...(1L)).thenReturn(new User("张三"));// 返回nullwhen(userRepository.findById(999L)).thenReturn(null);// 抛出异常...when(userRepository.findById(-1L)).thenThrow(new IllegalArgumentException("用户ID不能为负数"));```参数匹配器Mockito...提供了强大的参数匹配器,让你能够更灵活地定义行为:```java// 匹配任意Long类型参数when(userRepository.findById(anyLong())).thenReturn(defaultUser...);// 匹配特定条件when(userRepository.findById(longThat(id -> id > 100))).thenReturn(vipUser);// 匹配字符串when(userRepository.findByName
(comparable.compareTo("Test")).thenReturn(1); when(comparable.compareTo("Omg")).thenReturn(2);...(list.get(anyInt())).thenReturn(1); when(list.contains(argThat(new IsValid()))).thenReturn(true);...(spy.get(0)).thenReturn(3); //使用doReturn-when可以避免when-thenReturn调用真实对象api doReturn(999).when...(mockList.get(0)).thenReturn(0); when(mockList.get(0)).thenReturn(1); when(mockList.get(0)).thenReturn...- 当调用其get方法获取第0个元素时,返回"first" Mockito.when(mockedList.get(0)).thenReturn("first"); 在Mock对象的时候,创建一个proxy

使用 thenReturn、doReturn设置方法的返回值 thenReturn 用来指定特定函数和参数调用的返回值。thenReturn 中可以指定多个返回值,在调用时返回值依次出现。...import org.junit.Assert; import org.junit.Test; import static org.mockito.Mockito.*; import org.mockito.MockitoAnnotations...(mockRandom.nextInt()).thenReturn(1); Assert.assertEquals(1, mockRandom.nextInt()); }...org.mockito.ArgumentMatchers.anyInt; import static org.mockito.Mockito.when; import static org.mockito.Mockito...(exampleService.add(1, 2)).thenReturn(100); when(exampleService.add(2, 2)).thenReturn(100);
灵活的StubbingMockito的stubbing功能非常强大,支持各种复杂的场景:```java// 简单返回值when(mockList.get(0)).thenReturn("第一个元素");...;// 连续调用返回不同值when(mockList.size()) .thenReturn(1) .thenReturn(2) .thenReturn(3);// 根据参数返回不同结果...Mockito提供了丰富的参数匹配器:```java// 任意字符串when(mockService.process(anyString())).thenReturn("处理成功");// 任意整数when...(mockService.calculate(anyInt(), anyInt())).thenReturn(100);// 具体值匹配when(mockService.getUser(eq(1L)))....thenReturn(user);// 自定义匹配器when(mockService.processUser(argThat(user -> user.getAge() > 18))) .thenReturn
