在控制器测试中使用测试辅助函数

Question

当我尝试使用测试辅助函数时出现以下错误：

undefined function myfunction/0

设置如下：

defmodule MyAppWeb.DashboardControllerTest do
  use MyAppWebWeb.ConnCase

  import TestHelpers

  describe "index" do
    setup [:myfunction] #<- This works perfectly
  
    test "some test", %{conn: conn} do
      conn = get(conn, "/")

      var = myfunction #<- This does not work
    end
  end
end

测试助手看起来像这样：

# File is located in "support/test_helpers.ex"

defmodule TestHelpers do

  def myfunction(_) do
   #magic!
  end
end

如果有人能详细说明就太好了！提前致谢！

编辑 - 完整堆栈跟踪和版本：

我找到了解决方案...我只需要更改

import TestHelpers 到 import MyAppWeb.TestHelpers.
