Hi! Is it possible to create an extension on enum to get a random value. I have severals enum and for my test, I want to get a random value of this enum. Is it possible?

[diesieben07]

inline fun <reified E : Enum<E>> randomValue(): E {
    return randomValue(E::class.java)
}

fun <E : Enum<E>> randomValue(cls: Class<E>): E {
    return cls.enumConstants.random()
}

Usage:

val rnd = randomValue<Foo>()
// or
val rnd = randonValue(Foo::class.java)

Exactly what I want! thanks!

YourEnumClass.values().withIndex().shuffled().first().value

That is way slower.

enumValues<E>().let { it[Random.nextInt(size)] }
