Java – match an array of objects using mockito

I'm trying to set up a simulation for a method that requires an array of request objects:

client.batchCall(Request[])

I've tried these two variants:

when(clientMock.batchCall(any(Request[].class))).thenReturn(result);
...
verify(clientMock).batchCall(any(Request[].class));

and

when(clientMock.batchCall((Request[])anyObject())).thenReturn(result);
...
verify(clientMock).batchCall((Request[])anyObject());

But I can tell that ridicule was not quoted

They all cause the following errors:

Argument(s) are different! Wanted:
clientMock.batchCall(
    <any>
);
-> at com.my.pkg.MyUnitTest.call_test(MyUnitTest.java:95)
Actual invocation has different arguments:
clientMock.batchCall(
    {Request id:123},{Request id:456}
);

Why does the matcher not match the array? Is there a special matcher that I need to use to match an array of objects? The closest I found was additive matches Aryeq(), but this requires me to specify the exact contents of the array. I'd rather not do it

Solution

So I quickly put things together to see if I can find your problem. Here is the sample code I use any (class) matcher and how it works So there are some things we don't see

test case

@RunWith(MockitoJUnitRunner.class)
public class ClientTest
{
    @Test
    public void test()
    {
        Client client = Mockito.mock(Client.class);

        Mockito.when(client.batchCall(Mockito.any(Request[].class))).thenReturn("");

        Request[] requests = {
            new Request(),new Request()};

        Assert.assertEquals("",client.batchCall(requests));
        Mockito.verify(client,Mockito.times(1)).batchCall(Mockito.any(Request[].class));
    }
}

Client class

public class Client
{
    public String batchCall(Request[] args)
    {
        return "";
    }
}

Request class

public class Request
{

}
