这个测试辅助文件对压缩的压力很大。

- UglifyJS 压缩它需要占用 1.5GB 内存。
- Terser 占用略高于 1GB，耗时 40 秒。相比之下，同一台服务器处理 Ember+jQuery 仅需 8 秒 😱

@eviltrout 我们真的需要在生产环境中保留这个文件吗？

哦，看起来它来自 @Osama 的这次更改：

> This PR allows site admins to run theme tests in production via a new \`/theme-qu…nit\` route. When you visit \`/theme-qunit\`, you'll see a list of the themes/components installed on your site that have tests, and from there you can select a theme or component that you run its tests.
> 
> We also have a new rake task \`themes:install\_and\_test\` that installs a list of themes/components on a temporary database and runs the tests of the themes/components that are installed. This rake task can be useful when upgrading/deploying a Discourse instance to make sure that the installed themes/components are compatible with the new Discourse version being deployed, and if the tests fail you can abort the build/deploy process so you don't end up with a broken site.
