Hey everyone!

is there any assertion which can understand a mapped object is based on another class?

Let's say I have:
val p = Person (name='Sam', age= 30)

and there is function that I want to test and returns 'mapped' version of Person, sth like:

val mp = MappedPerson(name, age, someotherParam)

mp shouldBeDerivedFrom* m

(*shouldBeDerivedFrom doesn't exist I'm just writing my thoughts)
I think this can be helpful in layered architecture tests.
Any idea?

there’s shouldBeEqualToComparingFields which uses reflection and thus requires JVM

but you could always create your own utility function, which is usually what I prefer - it’s a bit more work but it tends to be more understandable and works better in practice

infix fun Person.shouldBeMappedTo(mp: MappedPerson) { TODO() }

Thanks Adam
I like the idea of creating my own functions for domain objects
