ValidField

ValidField allows you to unit test changesets

Usage

Add valid_field to your list of dependencies in mix.exs:

def deps do
  [{:valid_field, "~> 0.2.0", only: :test}]
end

Then in your unit test:

defmodule App.UserTest do
  import ValidField
  alias App.User

  test ".changeset - Validations" do
    with_changeset(%User{})
    |> assert_valid_field(:email, ["something@else.com"])
    |> assert_invalid_field(:email, ["", nil, "test"])
    |> assert_valid_field(:password, ["password123!"])
    |> assert_invalid_field(:password, [nil, "", "test", "nospecialcharacters1", "nonumber!"])
  end
end

Alternatively you can combine the assert_valid_field/3 and assert_invalid_field/3 syntax into assert_field/4. Refactoring the same example above using assert_field/4 would yield:

defmodule App.UserTest do
  import ValidField
  alias App.User

  test ".changeset - Validations" do
    with_changeset(%User{})
    |> assert_field(:email, ["something@else.com"], ["", nil, "test"])
    |> assert_valid(:password, ["password123!"], [nil, "", "test", "nospecialcharacters1", "nonumber!"])
  end
end
