Is there a way to generate random dates for property tests using Scalacheck . I want to generate both future and past dates . But the existing Scalacheck.Gen class does not provide any predefined method to do so .

          The following will generate what you are looking for



          implicit val localDateArb = Arbitrary(localDateGen)

          def localDateGen: Gen[LocalDate] =
          val rangeStart = LocalDate.MIN.toEpochDay
          val currentYear = LocalDate.now(UTC).getYear
          val rangeEnd = LocalDate.of(currentYear, 1, 1).toEpochDay
          Gen.choose(rangeStart, rangeEnd).map(i => LocalDate.ofEpochDay(i))
