How to get a sample of a generator?
问题 I'm using Triq to write my property based test. How can I see what kind of data my generator produces? Let's say I have the following generator: -module (my). -include_lib("triq/include/triq.hrl"). -export([valid_type_gen/1]). valid_type_gen() -> non_empty(list(any())). I would like to examine what kind of data it generates, i.e. something like: $ rebar3 shell 1> my:valid_type_gen().sample() %??? [1,b,"blah"] 回答1: Ok, I figured it out, I just need to call the sample function: 1> hd(triq_dom
