How to mock an instance variable using Mockito in java?

I'm a noob to unit testing and use of mockito

I have a class

public class SystemTenancyConfig {
    private String systemTenancy;
}

I have used this in another class where I'm getting the value:


@Inject
SystemTenancyConfig systemTenancyConfig;
String val = systemTenancyConfig.getsystemTenancy();

How do I mock systemTenancyConfig.getsystemTenancy() to be set to a string say "Test"? UpdatE:

    @Mock
    private SystemTenancyConfig systemTenancyConfig;
       when(systemTenancyConfig.getSystemTenancy()).thenReturn("test");

is giving me a NPE

the condition when getsystemTenancy will trigger your mock

when(systemTenancy.getsystemTenancy()).thenReturn(what you want it return);
    systemTenancy.getsystemTenancy()

also @Mock over the Object you want to mock the whole Object

example

@Inject
private SystemTenancyConfig systemTenancyConfig;

@Test
function void testingSomething(){
   when(systemTenancyConfig.getSystemTenancy()).thenReturn("test"); // condition to trigger the mock and return test
   String val = systemTenancyConfig.getsystemTenancy();
}
