我可以毫无问题地运行应用程序

我在实际应用程序中对Elm的唯一引用是在我的HTML索引文件中

<!DOCTYPE html>
<html>
  <head>
    <link rel='shortcut icon' type='image/x-icon' href='/favicon.ico' />
    <link rel="stylesheet" href="/main.css">
    <title>Print Albums</title>
  </head>

  <body>
    <div id="elm-app"></div>

    <script src="elm-compiled.js"></script>
    <script>
      const app = Elm.Main.embed(document.getElementById("elm-app"));
      app.ports.grabToken.send(window.location.search);
    </script>
  </body>
</html>

印刷相册
const-app=Elm.Main.embed(document.getElementById(“Elm-app”);
app.ports.grabToken.send(window.location.search);
你知道会出什么问题吗?jest似乎出于某种原因进入了我的Elm依赖项,而不仅仅是我的测试文件


干杯

好的,堆栈溢出再次被证明是一个伟大的橡皮鸭

发生的情况是:

  • 我在client文件夹中开发Elm应用程序
  • 客户机文件夹的某些依赖项具有与正在搜索测试的jest regexp匹配的测试文件夹
解决方案是将
client
添加到jest忽略的模式列表中

  testPathIgnorePatterns: [
    "/node_modules/", "/client/"
  ],
  testPathIgnorePatterns: [
    "/node_modules/", "/client/"
  ],
