Verify whether one of three methods is invoked with mockito

Question

I have three methods like these ones:

public void method1(String str){
    ...
}

public void method1(String str, String str2, String str3){
    ...
}

public void method1(String str, String str2, Object[] objs, String str3){
    ...
}

I want to check in Mockito if any of these methods are invoked, so I've tried to use anyVararg Matcher:

verify(foo).method1(anyVararg());

but this doesn't compile "The method method1(String, String) in the type Errors is not applicable for the arguments (Object)"

I have two questions:

1. How can I solve this?
2. Is there any way to check if any of two methods are invoked? Imagine I have another mathods called method2 and method3. I'd like to check if any of them is invoked (but at least one).

Thanks.

Answer 1

You could do this by using an Answer to increment a counter if any of the methods are called.

private Answer incrementCounter = new Answer() {
    public Object answer(InvocationOnMock invocation) throws Throwable {
        counter++;
        return null;
    }        
};

Note that you need to stub all methods. A method's uniqueness is based on its signature and not just the method name. Two methods with the same name are still two different methods.

doAnswer(incrementCounter).when(mockObj.method1(anyString()));
doAnswer(incrementCounter).when(mockObj.method1(anyString(), anyString()));
doAnswer(incrementCounter).when(mockObj.method2(anyString()));

See documentation for doAnswer here.
