Changing the Size of Sized Generators

To change the default size used by sized generators we can use size test aspect:

import zio._
import zio.test.{ test, _ }

test("generating small list of characters") {
  check(Gen.small(Gen.listOfN(_)(Gen.alphaNumericChar))) { n =>
    ZIO.attempt(n).debug *> Sized.size.map(s => assertTrue(s == 50))
  }
} @@ TestAspect.size(50) @@ TestAspect.samples(5)

Sample output:

List(p, M)
List()
List(0, m, 5)
List(Y)
List(O, b, B, V)
+ generating small list of characters
