Couch Factory

Implementing factory_girl in Elixir, with support for persisting documents into a couchdb server.

Sort of inspired by factory girl elixir, but with a different API.

Document public functions
Add sequences
Handle conflicts when creating documents
Auto namespacing on document ids

usage

You will need couchdb server up and running

defp deps do
  [
    {:couch_factory, git: "git@github.com:javierg/couch_factory.git", branch: "master"}
  ]
end

Or oyu can use Hex

defp deps do
  [
    {:couch_factory, "0.1"}
  ]
end

Which will require you to add to your app dependencies couchbeam

defp deps do
  [
    {:couchbeam, git: "git://github.com/benoitc/couchbeam.git", branch: "master"},
    {:couch_factory, "0.1"}
  ]
end

Update the applications list to include both projects:

def application do
  [applications: [:couch_factory]]
end

Add on your config/config.exs the couch_factory db config

config :couch_factory, CouchFactory.Db,
  host: "http://localhost:5984",
  db: "factory_test",
  user: "",
  password: ""

You will need to create the db manually. But probably is a good idea to add a config task for this...

Run mix deps.get in your shell.

Defining a Factory

defmodule Factory do
  use CouchFactory.Factory

  factory :user,
    _id: "user/octavio@paz.com",
    name: "Octavio Paz",
    email: "octavio@paz.com"

end

On your tests now you can do

test "will do something" do
  expected = {[{"_id", "user/octavio@paz.com"}, {"name", "Octavio Paz"}, {"email", "octavio@paz.com"}]}
  assert expected == Factory.build(:user)
end

test "this is persisted" do
  assert {:ok, user} = Factory.create(:user)
end

test "override properties" do
  expected = {[{"_id", "user/octavio@paz.com"}, {"name", "Octavio Paz"}, {"email", "octavio@war.com"}]}
  assert expected == Factory.build(:user, email: "octavio@war.com")
end

If you need a map of properties you can use

test "will return map of properties" do
  expected = %{_id: "user/octavio@paz.com", name: "Octavio Paz", email: "octavio@paz.com"}
  assert extected == Factory.properties_for(:user)
end

And you can override properties

test "will return map of properties" do
  expected = %{_id: "user/octavio@paz.com", name: "Octavio War", email: "octavio@paz.com"}
  assert extected == Factory.properties_for(:user, name: "Octavio War")
end
