Verify whether one of three methods is invoked with mockito

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.

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.

You can intercept all calls on object like in this answer: Mockito - intercept any method invocation on a mock and then put combine this with approach suggested by @Bozho:

private Answer incrementCounter = new Answer() {
    public Object answer(InvocationOnMock invocation) throws Throwable {
        if (invocation.getMethod().getName().eqauls("someMethid")) {
            counter++;
        }
        return null;
    }        
};

VendorObject mockObj = mock(SomeClass.class, incrementCounter);

Note: if you provide other interceptor for any of this methods - default will not be invoked.

A vararg method has a signature like this:

public void myMethod(String ... arguments){}

None of your methods is a vararg method.

I don't know Mockito so I can't solve your problem for you, but there is no possible abstraction over all three of the above methods unless you use reflection, so I guess you will have to use separate cases for each of the above methods.
