java - 预期 3 个匹配器，记录 4 个

Question

我在模拟录制期间收到此异常。我尝试在此论坛中搜索解决方案，并确保我没有弄乱任何其他参数。

下面的模拟期望给出了错误。

EasyMock.expect(slotManager.addSlotPageletBinding(EasyMock.isA(String.class), EasyMock.isA(String.class), EasyMock.isA(helloWorld.class))).andReturn(true);

在此声明之前，我对具有两个参数(重载方法)的同一方法有另一个模拟期望。下面是那个模拟。

EasyMock.expect(slotManager.addSlotPageletBinding(EasyMock.isA(String.class),EasyMock.isA(String.class))).andReturn(true).anyTimes();

有人可以指导我吗？谢谢。

问题是您记录了模拟的 3 次期望(调用)，但在测试执行时有 4 次模拟方法调用。所以你在某个地方错过了一个电话。尝试阅读更多被测代码并发现丢失的调用。或者使用调试器来发现它。
