I need mock as when(new A(any(B.class))).thenReturn(any(A.class));
because my code have function:
B b = new B; A a = new A(b); C c = a.processing();
but return error:
org.mockito.exceptions.misusing.InvalidUseOfMatchersException:
Misplaced or misused argument matcher detected here:
-> at .......
You cannot use argument matchers outside of verification or stubbing.
Examples of correct usage of argument matchers:
when(mock.get(anyInt())).thenReturn(null); doThrow(new RuntimeException()).when(mock).someVoidMethod(anyObject()); verify(mock).someMethod(contains("foo"))
This message may appear after an NullPointerException if the last matcher is returning an object
like any() but the stubbed method signature expect a primitive argument, in this case,
use primitive alternatives.
when(mock.get(any())); // bad use, will raise NPE
when(mock.get(anyInt())); // correct usage use
Also, this error might show up because you use argument matchers with methods that cannot be mocked.
Following methods cannot be stubbed/verified: final/private/equals()/hashCode().
Mocking methods declared on non-public parent classes is not supported.
What should I do? Thanks all
