Mocked method not invoked - mockito

Question

public class Employee {
public void getAddress(){
Address add = new Address();
String a = add.addAddress();
System.out.println(a);
}
}
public class Address {
public String addAddress(){
return "Emp Address";
}
}
public class MockitoTest {
#Mock
Address add;
#Before
public void setup(){
MockitoAnnotations.initMocks(this);
}
#Test
public void testEmployee(){
when(add.addAddress()).thenReturn("mocked address");
Employee e = new Employee();
e.getAddress();
}
}
In the above example, I want to mock addAddress() method in address class.When I run mockito,it is calling the real method addAddress() than the mocked one and printing "Emp Address",instead of "mocked address".I need "mocked address" as output.

Answer 1

Problem is as mentioned by #pvpkiran in the question comment. If you want to have mocked behavior, you need to provide provision to pass the mocked Address object to Employee.
One way to do that is
public class Employee {
public void getAddress(Address add) {
String a = add.addAddress();
System.out.println(a);
}
}
public class MockitoTest {
#Mock
Address add;
#Before
public void setup(){
MockitoAnnotations.initMocks(this);
}
#Test
public void testEmployee(){
when(add.addAddress()).thenReturn("mocked address");
Employee e = new Employee();
e.getAddress(add);
}
}
Edited: With Powermock (tested with org.powermock:powermock-mockito-release-full:1.6.4)
import static org.mockito.Mockito.when;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mock;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
class Employee {
public void getAddress() {
Address add = new Address();
String a = add.addAddress();
System.out.println(a);
}
}
class Address {
public String addAddress() {
return "Emp Address";
}
}
#RunWith(PowerMockRunner.class)
#PrepareForTest(Employee.class)
public class MockitoTest {
#Mock
Address add;
#Test
public void testEmployee() throws Exception {
when(add.addAddress()).thenReturn("mocked address");
PowerMockito.whenNew(Address.class).withNoArguments().thenReturn(add);
Employee e = new Employee();
e.getAddress();
}
}
