运行 单元测试中的变量成功 - Node、Mocha、Chai、Karma、Grunt
Variable success in running unit tests - Node, Mocha, Chai, Karma, Grunt
我有一个围绕 JavaScript 应用程序代码构建的测试套件，其中包含约 350 个测试。我的测试是 运行 by 运行ning grunt test 来自节点命令行。每次测试 运行，在它停止之前我的测试数量不同 运行。它很少完成我所有的测试。以前有没有人发生过这种事情？关于可能导致它的原因有什么想法吗？
当我运行测试时，我通常会得到一个看似随机的数字，从270 - 350 测试完成。测试后，我没有得到任何错误或任何东西。它的结尾是这样的：
Finished in 1.332 secs / 0.823 secs

当我 运行 将测试作为单个 运行 时，它会说由于警告而中止。有一些关于执行整页重新加载的测试的警告。所以，我删除了两个函数的测试：
请求桌面版本：添加 cookie 并重新加载页面以仅获取桌面样式。
请求移动版本：删除 cookie 并重新加载以获取移动样式
删除这些后，我得到了一致数量的测试完成消息 "Done, without errors."
