With the templates out of the way, the hard work is mostly done.

Building quizzes

We can focus on building quizzes now, which is nearly trivial at this point. We’ll add the following code to /test/support/quiz_builders.exs:

Press + to interact
  def quiz_fields(overrides) do
    Keyword.merge([title: "Simple Arithmetic"], overrides)
  end
  def build_quiz(quiz_overrides \\ []) do 
    quiz_overrides
    |> quiz_fields
    |> Quiz.new
  end
  def build_question(overrides \\ [ ]) do 
    overrides
    |> template_fields
    |> Template.new
    |> Question.new
  end

  • Our quiz_fields function returns some default attributes and merges in overrides.

  • Then all build_quiz has to do is take the overrides, pipe them into quiz_fields, and pipe that into Quiz.new. ...
