Let’s start by generating a language code.

1

val genLanguageCode: Gen[LanguageCode] = Gen.oneOf(LanguageCodes.all)

Generate LanguageCode

Using the Gen.oneOf helper from the library makes the code extremely simple.

ScalaCheck generate UUID

Generating a UUID is nothing special, either.

12

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.
