Tapping a random item from a list

christianIMVU · February 2017

I am building the tests for creating a character in my app. We have multiple skin tones and clothing options and I need an easy way to select a random one.

The items all have the same ID and have no differentiating factors between them unless I rip the URL from it (which I don't want to do.). I was able to get random selections in Calabash with a simple solution but finding one in C# is proving a bit more difficult.

app.Tap(x=>x.Id("image"); will always tap the first item in the list.

var item = app.Query(x=>x.Id("image"));

        Random rnd = new Random();

        var i = rnd.Next(item.GetLength(0));

        app.Tap(x => x.Equals(item[i]));

Is there a way for a query to target a particular result?
