How to use Mockito BDD to mock a Class<?> return type method?

[Jiaqian Sun]

I'm having trouble to use Mockito BDD to mock the method whose return type is Class<?>

I'm trying to use BDD to mock this method:

public Class<?> getInterfaceClass() {
if (this.interfaceClass == null) {
try {
this.interfaceClass = this.getClass().getClassLoader().

loadClass(this.interfaceType);
} catch (ClassNotFoundException var2) {
throw new RuntimeException(var2);
} catch (NullPointerException var3) {
return null;
}
}

return this.interfaceClass;
}

This is how I mocked:

given(serviceFactoryBean.getInterfaceClass()).willReturn

(Comparable.class);

But I got this error: Cannot resolve method 'willReturn(Class<Comparable>)'

May I know how to resolve this problem?
