Hi, think its a stupid question but do we need to install

kotlin.test

from somewhere else? For what I understood the references says

kotlin.test

is a core library (https://kotlinlang.org/api/latest/kotlin.test/index.html) but when I try to use

@Test

annotation, Intellij tells me it is not defined What should I do to use kotlin.test library? Thanks in advance.

Add

kotlin("test-junit")

dependency assuming you're on JVM platform.
