I have below two classes :
public class Employee {
public static int count() {
throw new UnsupportedOperationException();
}
}
public class EmployeeService {
public int getEmployeeCount() {
return Employee.count();
}
}
I wrote below test class to test the EmployeeService :
@RunWith(PowerMockRunner.class)
@PrepareForTest(Employee.class)
public class EmployeeServiceTest {
@Test
public void testGetEmployeeCount() {
PowerMockito.mockStatic(Employee.class);
PowerMockito.when(Employee.count()).thenReturn(900);
EmployeeService employeeService = new EmployeeService();
Assert.assertEquals(900,employeeService.getEmployeeCount());
}
}
Dependencies used for mockito and power mockito are as follows:
- mockito-all-1.10.19.jar
- powermock-mockito-1.6.2-full.jar
- objenesis-2.1.jar
- cglib-nodep-2.2.2.jar
To resolve the exception I also added javassist-3.12.0.GA-sources.jar to the classpath but it did not help.
But getting exception as shown above. Kindly help me out.
