用PowerMock mock final類

mock final類相對簡單，直接貼代碼

被測方法：

public class FinalEmployeeService {

    public void insertEmployee(Employee employee) {
        FinalEmployeeDao employeeDao = new FinalEmployeeDao();
        employeeDao.insertEmployee(employee);
    }
}

final 類

final public class FinalEmployeeDao {

    public boolean insertEmployee(Employee employee) {
        throw new UnsupportedOperationException();
    }
}

測試類：

@PrepareForTest(value={FinalEmployeeDao.class,FinalEmployeeService.class})
public class EmployeeServiceTestWithFinalClassTest extends PowerMockTestCase{
    @ObjectFactory
    public ITestObjectFactory getObjectFactory() {
        return new PowerMockObjectFactory();
    }
    
    @Test
    public void test() throws Exception {
        FinalEmployeeDao employeeDao = PowerMockito
                .mock(FinalEmployeeDao.class);
        Employee employee = new Employee();
        PowerMockito.whenNew(FinalEmployeeDao.class).withNoArguments().thenReturn(employeeDao);
        PowerMockito.when(employeeDao.insertEmployee(employee)).thenReturn(true);
        FinalEmployeeService employeeService = new FinalEmployeeService();
        employeeService.insertEmployee(employee);
        Mockito.verify(employeeDao).insertEmployee(employee);
    }
}
