EasyMock void method When we use expectLastCall () and andAnswer () to mock void methods, we can use getCurrentArguments () to get the arguments passed to the method and perform some action on it. For details, see. Expects an int argument less than or equal to the given value. Then you put the mock in replay mode but don't tell it what methods to expect, so the mock expects no methods to be called. Not noticing that I did initialize the long[] separately as. object that isn't thread safe to make sure it is used correctly in a The invocation count is mentioned using once(), times(exactCount), times(min, max), atLeastOnce() and anyTimes().
