      # 1) Start ExUnit. You can pass some options
      #    (see `configure/1` for the list of options)
      ExUnit.start

      # 2) Create a new test module (test case) and use ExUnit.Case
      defmodule AssertionTest do
        # 3) Notice we pass async: true, this runs the test case
        #    concurrently with other test cases
        use ExUnit.Case, async: true

        # 4) A test is a function whose name starts with
        #    test and receives a context
        def test_always_pass(_) do
          assert true
        end

        # 5) It is recommended to use the "test" macro instead of def
        test "the truth" do
          assert true
        end
      end

  To run the test above, all you need to do is to run the file
  using `elixir` from the command line. Assuming you named your file
  `assertion_test.exs`, you can run it as:

      bin/elixir assertion_test.exs

  ## Case, callbacks and assertions

  See `ExUnit.Case` and `ExUnit.Callbacks` for more information about
  defining test cases.

  The `ExUnit.Assertions` module contains a set of macros to easily
  generate assertions with appropriate error messages.

  ## Integration with Mix

  Mix is the project management and build tool for Elixir. Invoking `mix test`
  from the command line will run tests in each file matching the pattern
  `*_test.exs` found in the `test` directory of your project.

  By convention, you could also create a `test_helper.exs` file inside the
  `test` directory and put the code common to all tests there.

  The minimum example of a `test_helper.exs` file would be:

      # test/test_helper.exs
      ExUnit.start

  Mix will load the `test_helper.exs` file before executing the tests. 
  It is not necessary to `require` the `test_helper.exs` file in your test files.
  See [`Mix.Tasks.Test`](Mix.Tasks.Test.html) for more information.
