Random RepeatCount in AutoFixture

Question

How can I set up AutoFixture so that when it generates an iterable, the RepeatCount will be different each time? I know I can manually change it each time, but I was wondering if there's some setting that I can change when I initialize the fixture.

Answer 1

AutoFixture doesn't have such a feature, but in a pinch, you can do something like this:

var fixture = new Fixture();
var rnd = new Random();

var foos = fixture.CreateMany<Foo>(rnd.Next(10));

or

var fixture = new Fixture();
var rnd = new Random();

var foos = fixture.Create<Generator<Foo>>().Take(rnd.Next(10));

If, however, you're interested in taking a more principled step in that direction, you should look at FsCheck or Hedgehog.
