ExUnit.CaseTemplate View Source

This module allows a developer to define a test case template to be used throughout their tests. This is useful when there are a set of functions that should be shared between tests or a set of setup callbacks.

By using this module, the callbacks and assertions available for regular test cases will also be available.

Example 

defmodule MyCase do
  use ExUnit.CaseTemplate

  setup do
    IO.puts "This will run before each test that uses this case"
  end
end

defmodule MyTest do
  use MyCase, async: true

  test "truth" do
    assert true
  end
end
