StreamData: how to generate a list of 2 strings with varied length
Hi!, how do i generate a list contains only 2 strings with varied length ie [“foo”, “baaar”]?
I tried:
# returns ["QrGgkWA7o1", "NbWbClnTYk"]
Enum.take(StreamData.string(:alphanumeric, length: 10), 2)
Marked As Solved

yeah @soyjeansoy it starts with the smallest strings and progresses into bigger lengths, not sure how “random” that can be.
iex(1)> StreamData.string(:alphanumeric) |> Enum.take(2)
["D", "k"]
iex(2)> StreamData.string(:alphanumeric) |> Enum.take(2)
["E", "yj"]
iex(3)> StreamData.string(:alphanumeric) |> Enum.take(20)
["j", "g", "yLc", "", "DxC8", "", "n", "q9kgIX", "", "Jg", "b", "jJs1",
"3UrpsF", "IcNUZBQ", "NC70Mt6Y4Daa", "s61D8798DT", "KiBfNzUonUT0Bg", "DVWUXgE",
"5J3s6GlISUrIGE", "SQLtS0KHTakmLhU"]
iex(4)> StreamData.string(:alphanumeric, max_length: 12) |> Enum.take(83)
["b", "LE", "", "", "H", "kMYa", "", "4hZuN", "jJ3dy", "0mGT9", "FURUUin",
"DzOI", "TTZhhaw6N9", "82vV", "nOYc1QH7", "4BWy", "OLeM4nH53Qw", "TDgXLM",
"tRl4ldXT", "vtu3H", "ZgRk", "", "o9xU", "S7wMlwblNv", "l3O0elqjVs1I",

"QFYnr", "uNIp", "kmbMS", ...]
You can pass a min_length if you don’t want them too small.
