Issue with org.mockito.Matchers.any() and jmockit

Question

I have one UT using jmockit and mockito

in this UT,I have one field @Tested TestService testService

testService have one method using Car as parameter : testService.doTest(Car car)

then my UT: testService.doTest(any(Car.class))

when I debug this UT I found that testService.doTest(any(Car.class)) always pass null into doTest(car),what if I want an instance of Car in doTest(car)?

I tried (Car)any(),(Car)anyObject(),none of them help,any ideas?

updated: I Have code:

class TestService{
    @AutoWired
    Dependency dependency;

    doTest(Car car){
        dependency.doSomeThing(car);
        print(car.toString());
    }
}

UT code:

@Injectable Dependency mockDependency;
@Tested TestService testService;
//record 
new Expectations() {{
    mockDependency.doSomeThing((Car)with(any));
    result=detailCar;
}};
//call verify
new Verifications(){{
    codeResult=testService.doTest((Car)with(any))
    //some codeResult assert
}};

this all jmockit version,I get NullPointerException at car.toString()

if I change it to:

new Verifications(){{
    codeResult=testService.doTest(new Car())
    //some codeResult assert
}};

or

final Car car;
new Verifications(){{
    codeResult=testService.doTest(car)
    //some codeResult assert
}};

I get MissingInvocation at codeResult=testService.doTest(...) seems instance car don't match (Car)with(any)

Answer 1

Mock car = mock(Car.class) and pass this car in doTest. Hope it ll help Also if you are calling any method of Car, make sure you also define the behaviour. for eg

when(car.getName(anyString())).then("bmw");
