I have two objects that have some features in common that I would like to compare
data class Pet(val colour: String, val owner: Human, val legCount: Int)
data class Car(val colour: String, val owner: Human, val isElectric: Boolean)
I would like to assert that some element in a List<Car>
contains an element with the same colour and owner as a given Pet
.
Here's a fake code example to illustrate what I'm trying to do:
cars.containsElementSatisfying { car ->
pet.colour shouldBe car.colour
pet.owner shouldBe car.owner
}
How might I do this using kotest? I can accomplish the desired functionality using assertJ's anySatisfy assertion.
I found the solution. The "Inspectors" kotest library contains a number of functions similar to assertJ's anySatisfy
assertion, in particular the collection functions forAtLeastOne
and forAtLeast(k)
Here's example usage:
cars.forAtLeastOne { car ->
pet.colour shouldBe car.colour
pet.owner shouldBe car.owner
}
