如何在Junit测试这种布尔方法？

Question

请需要测试此方法paramsRequired，但不是因为它可以重现测试行为。如何知道传递 null 参数时该方法是否会跳过 if？

我的班级服务

public class TestStack {
private GeoClassService service;

    public Address getAddress(String city,String neighborhood, boolean listOut) {
        List<GeoLocation> listLocation = new ArrayList<>();
        FutureTask<List<GeoLocation>> returnLoc = null;
    
        Address location = new Address();
        boolean paramsRequired = city!=null || neighborhood!=null;
        if (listOut && paramsRequired) {
            returnLoc = new FutureTask<>(() -> 
                    service.getAdrres(city,neighborhood, listOut));
            execute.executor(returnLoc);
        }
       return location;
        
    }

}

我的单元测试

public class TestStackTests {

    @InjectMocks
    private TestStack stack;
    
    @Test
    public void paramsTest() {
        Address paramsRequired = Mockito.spy(stack.getAddress(
                "any city", "any", true));
        
        boolean newAddres = paramsRequired==null;
    
        Assert.assertFalse(newAddres);
    }

}

我不认为我正在测试任何东西，但老实说，我不知道如何进行这个测试
