Examples

defmodule Assignment.Fixtures do
  use ExUnit.CaseTemplate

  setup _context do
    %{
      example: %{}
    }
  end
end

Implementation

defmodule Assignment do
  def run(input) when not is_nil(input) do
    %{}
  end
end

Testing

defmodule Test.Assignment do
  import Assignment
  use ExUnit.Case, async: true
  use Assignment.Fixtures

  describe "Assignment.run/1" do
    test "it works", %{example: example} do
      assert run(example) == example
    end

    test "nil throws an error" do
      assert_raise FunctionClauseError, "no function clause matching in Assignment.run/1", fn ->
        run(nil)
      end
    end
  end
