Test class whether does it implements serializable

Question

I have a class that implements serializable and I need it to be there.

public class Alpha implements Beta {
}

Is there a way to check that it is implementing Beta via a unit test?

why have you attached kotlin tag? What you've posted is Java thou — muminers, Mar 11 '18 at 23:21
How are you testing the serialization of your class to begin with? (That's probably what you'd want to leverage to test this.) — Makoto, Mar 11 '18 at 23:45
Which is it? `Serializable` or `Beta`? (Not that it makes any difference.) — user207421, Mar 12 '18 at 00:05

The easiest way to test a class is just to require that type as a parameter:

public void someMethod( Beta b ) {
  // ...
}

For Serializable, just use that type.

public void otherMethod( Serializable ser ) {

If you need a class that implements two types, then you should make an interface that expresses that type.

public interface MyType extends Beta, Serializable {}

Then just use MyType wherever you need both types.
