用PowerMock mock final类

mock final类相对简单，直接贴代码

被测方法：

public class FinalEmployeeService {

    public void insertEmployee(Employee employee) {

        FinalEmployeeDao employeeDao = new FinalEmployeeDao();

        employeeDao.insertEmployee(employee);

    }

}

final 类

final public class FinalEmployeeDao {

    public boolean insertEmployee(Employee employee) {

        throw new UnsupportedOperationException();

    }

}

测试类：

@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);

    }

}
