3 matchers expected, 4 recorded

I get this exception during the mock recording time. I tried searching for a solution in this forum and made sure that I did not mess up any another parameter.

The below mock expectation is giving the error.

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

Before this statement I have another mock expectation on the same method with TWO parameters (overloaded method). Below is that mock.

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

Could any one guide me on this? Th开发者_如何学Goanks.

The problem is you recorded 3 expectations (calls) of your mock but while test executes there was 4 calls of mock's methods. So you've missed one call somewhere. Try to read more your code under test and discover missing call. Or use debugger to discover it.
