Feature Idea: Enums

[bnns]

It would be great if we could do something like:

def role_factory do
  %Role{
    name: enum(["owner", "admin", "guest"])
  }
end

which would behave like:

build(:role)
# %Role{name: "owner"}
build(:role)
# %Role{name: "admin"}

Wouldn't Enum.random/1 work for that case?

Something like:

Enum.random(["owner", "admin", "guest"])

in

def role_factory do
  %Role{
    name: Enum.random(["owner", "admin", "guest"])
  }
end

Yeah, kind of - but I was thinking of cases where you need at least 1 struct for each value. Besides creating a user for each role, another use-case for me is to build a struct per day of the week.

def schedule_factory do
  %Schedule{
    day_of_week: enum(["Sun", "Mon", "Tue", ...]),
    start_time: Ecto.Time.cast!("12:00:00Z"),
    end_time: Ecto.Time.cast!("3:00:00Z")
  }
end

The ability to go in order would nice for that situation.

Please have a look at this PR #227,

def schedule_factory do
  %Schedule{
    day_of_week: sequence(:weekdays, ["Sun", "Mon", "Tue"]),
    start_time: Ecto.Time.cast!("12:00:00Z"),
    end_time: Ecto.Time.cast!("3:00:00Z")
  }
end

Looks great! Thanks @suhrawardi. Closing this issue.
