Generating a UUID is nothing special, either.

val genUuid: Gen[UUID] = Gen.delay(UUID.randomUUID)

)

Generate UUID

We might be tempted to use Gen.const here, but we don’t because it will then become immutable.

Another option is using a list of randomly generated UUID values from which we then chose one. That would be sufficient for generators that only generate a single product, but if we want to generate lists of products, we would have duplicate IDs sooner or later.

ScalaCheck generate ProductName  

xxxxxxxxxx

val DefaultProductName: ProductName = "I am a product name!"

val genProductName: Gen[ProductName] = for {

  cs <- Gen.nonEmptyListOf(Gen.alphaNumChar)

  name = RefType.applyRef[ProductName](cs.mkString)

  .getOrElse(DefaultProductName)

} yield name
