Hello, I have a class like

class MyClass(val dir: File) {

  fun stuff(filesNames: List<String>) {
    ...
    val file = File(dir, fileName)
    if (file.exists())
    ...
  }
}

What would be the right way in order to pass the check if (file.exists()) ?

in isolation it looks like a use case for mockkClass. Example from https://mockk.io/ :

val car = mockkClass(Car::class)

every { car.drive(Direction.NORTH) } returns Outcome.OK

car.drive(Direction.NORTH) // returns OK

verify { car.drive(Direction.NORTH) }

I’m not sure though if this would work when File is instantiated inside of the method under test

But child File is created internally from the class, anyway I solved with

@get:Rule
val folder: TemporaryFolder = TemporaryFolder()
