polymer - Firefox 的 Web Component Tester 中的所有测试均失败

Question

在创建 Polymer Starter Kit 的干净副本后，使用 Web 组件测试器(“测试”Gulp 任务)运行测试会导致所有测试在 Firefox 中失败。

测试在 Chrome 和 IE 中运行良好。

错误是:

firefox 39               ✖ my-greeting-basic.html
  Timed out loading http://localhost:2000/components/polymer-starter/my-greeting-basic.html?

在浏览器中，对测试套件的调用导致 404。

问题是 Windows 中的 Firefox 在看到路径中的反斜杠时搞砸了。我花了很长时间才弄明白，但我已经在相关项目上开了一张票，并提交了一个拉取请求以解决我想出的问题。

如果您不耐烦，可以导航至 <your project>/node_modules/web_component_tester/runner/webserver.js并将以下内容放在第 80 行之前(options.webserver.webRunnerContent = INDEX_TEMPLATE(options))

options.suites = options.suites.map(function (cv) {
  return cv.replace(/\\/g,'/');
})

这会将路径中的反斜杠更改为 Firefox 没有问题的正斜杠。
