testem.js:
/*jshint节点:真*/

“框架”:“数量单位”，
"test_page": "tests/index.html?hidepassed",
“disable_watching”:是的，

下面是我的 tests/index.html 文件的一部分:

<script src="testem.js" integrity=""></script>
<script src="assets/vendor.js"></script>
<script src="assets/test-support.js"></script>
<script src="assets/myApp.js"></script>
<script src="assets/tests.js"></script>

也尝试使用 ember test --server 但同样的错误。所以任何人都知道如何缩小范围以及为什么 testem 没有加载？

Answer 1

对于测试，通常您需要在启用远程调试的情况下以 headless 模式运行 chrome。将这些行添加到您的 testem.json 应该会有所帮助:

"browser_args": {
  "Chrome": [
    '--headless',
    '--disable-gpu',
    '--remote-debugging-port=9222',
    '--window-size=1440,900',
  ]
}

我还建议删除“PhantomJS”行 - 由于 this issue，phantom 可能不适用于最近的 ember 版本.
