Mockito.when().thenReturn

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？...(500.00).thenReturn(0.0); when(stockService.getPrice(amazonStock)) .thenReturn(1000.00).thenReturn...(0.0).thenReturn(1.0);; assertThat(portfolio.getMarketValue()).isEqualTo(105000.0); assertThat...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。

在用Mockito做单元测试时如何使用doAnswer…when

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
