View Source ExUnit.CaseTemplate (ExUnit v1.12.3)

Defines a module template to be used throughout your test suite.

This is useful when there are a set of setup callbacks or a set of functions that should be shared between test modules.

Once a case template is used, the regular functionality in ExUnit.Case plus the functionality defined in the template will become 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
