Mockito: How to verify a method was called only once with exact parameters ignoring calls to other methods?
JavaUnit TestingTestingMockingMockitoJava Problem Overview
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:
verifyNoMoreInteractions(foo);
Nope. It does not allow calls to other methods like clear()
.
verify(foo, times(0)).add(any());
Nope. It does not take into account that we allow one call to add("1")
.
Java Solutions
Solution 1 - Java
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.
Solution 2 - Java
The previous answer can be simplified even further.
Mockito.verify(foo).add("1");
Mockito.verify(foo).add(Mockito.anyString());
The single parameter verify
method is just an alias to the times(1)
implementation.
Solution 3 - Java
verify(mock.methodName()).called(1// or any number that u should check);
