Mockito: How to verify a method was called only once with exact parameters ignoring calls to other methods?

Using Mockito in Java how to verify a method was called only once with exact parameters ignoring calls to other methods?

Sample code:

public class MockitoTest {

interface Foo {
void add(String str);
void clear();
}


@Test
public void testAddWasCalledOnceWith1IgnoringAllOtherInvocations() throws Exception {
// given
Foo foo = Mockito.mock(Foo.class);

// when
foo.add("1"); // call to verify
foo.add("2"); // !!! don't allow any other calls to add()
foo.clear(); // calls to other methods should be ignored

// then
Mockito.verify(foo, Mockito.times(1)).add("1");
// TODO: don't allow all other invocations with add()
// but ignore all other calls (i.e. the call to clear())
}

}


What should be done in the
TODO: don't allow all other invocations with add()
section?

Already unsuccessfully tried:


  1. verifyNoMoreInteractions(foo);



Nope. It does not allow calls to other methods like
clear()
.


  1. verify(foo, times(0)).add(any());



Nope. It does not take into account that we allow one call to
add("1")
.

Answer
Mockito.verify(foo, Mockito.times(1)).add("1");
Mockito.verify(foo, Mockito.times(1)).add(Mockito.anyString());

The first verify checks the expected parametrized call and the second verify checks that there was only one call to add at all.
