Install Chrome and then give it another try.

Oh sorry i’ve pasted an old error code which i had stored in a pastebin

Try running the test in the browser as David suggested earlier. So, in your browser, when the server is running, go to your-local-site/qunit. Very often, for me, timeouts in the Terminal have errors in JS that I could see and fix after visiting /qunit on the browser.

Machigatta · 2018 年11 月 22 日 18:12

Thats one of the problems

I can’t find acceptance tests on my /qunit

Even after turning on all modules and filtering it with box and humble nothing is here

david · 2018 年11 月 22 日 18:46

Try renaming the folder to test/javascripts/acceptance - that extra s is quite important!

https://github.com/discourse/discourse/blob/cd0403174dd88b0d1619ee7a53b42bc600bd69d1/lib/plugin/instance.rb#L463

You might need to do rm -rf tmp, and then restart your development server for the changes to take effect.

pmusaraj · 2018 年11 月 22 日 19:20

Do what David said above (rename the folder to javascripts), but ALSO, change the name of your plugin in plugin.rb to discourse-humble-box to match the folder name. I did these two changes, and I see tests locally:

Machigatta · 2018 年11 月 22 日 19:28

Yea i’ve seen those as well now, but these aren’t really eye-opening results tbh.

But gotta dig deeper and lookup why these errors are shown.

Thanks for the help guys.
For example the second test case… if i am testing it myself by hand… it works, but running it on qunit it fails

Ok, got a brief idea whats bringing me the errors and it confuses me:
http://localhost:9292/ in my browser has the plugin installed and working
http://localhost:9292/qunit the test shows, that the plugin is not even installed

I thought these two are using the same enviroment ?
Could this be caused by my local dev-enviroment since it’s not using docker and I’m not able to install the plugin like Install Plugins in Discourse ? It’s just sitting in the plugins folder like the others.

Machigatta · 2018 年11 月 30 日 17:40

Any idea how this is possible ?

我正在尝试遵循本指南，但在开始时就遇到了困难：我根本无法访问 /qunit。（这似乎也与 Install Discourse on Ubuntu or Debian for Development 相关，我基本上是采用这种方法在本地计算机上部署 Discourse 以学习开发，但本指南是触发我障碍的提示，所以我想把它放在这里。）尝试访问它会得到“该页面不存在或已私密”的响应。

/qunit 路由的控制器 (discourse/app/controllers/qunit_controller.rb at 166fe3bb34f99bd0baa613726486ce0f13c7a992 · discourse/discourse · GitHub) 提到它“仅用于非 ember-cli 测试/开发”（该方法之前的注释），因此我尝试使用 RAILS_ENV=test bundle exec rails server 运行实例，但 EmberCli.enabled? 仍然是 true。

你们使用什么方法来运行本地开发服务器，以便我们能够实际访问 /qunit（这可能涉及禁用 EmberCLI）？（我肯定可能忽略了一些显而易见的东西。）

david · 2022 年5 月 19 日 16:06

新路径是 /tests。我将更新 OP - 谢谢！

jlc · 2022 年5 月 19 日 17:43

太好了，谢谢！下一个障碍：

这个直接指向特定验收测试的链接会报错（并附有堆栈跟踪）：

Error: No tests matched the module "Acceptance: Purple Tentacle".

确实，当我通过“Module:”选择列表搜索时，我没有看到任何与“purple”或“Purple”匹配的内容。系统是否有新的部分用于注册插件或它们的测试，而这里可能遗漏了？

如果我使用“Filter:”文本框搜索“purple”，它会带我到以下 URL：http://localhost:4200/tests?filter=purple，这会给我另一个错误：

Error: Could not find module `helpers/qunit-helpers` imported from `discourse/plugins//acceptance/purple-tentacle-test`
    at missingModule (http://localhost:4200/assets/vendor.js:259:11)

您有什么关于哪里可能出错的想法吗？

顺便问一下，/tests URL 是否使用了“catch-all” get \"*url\", to: 'permalinks#show' 路由，因此使用 Permalink.find_by_url 来实际解析？如果是这样，/tests URL 映射是在 Discourse 初始化过程的哪个阶段加载到数据库中的？

@jlc，非常感谢您试用我们的指南并及时向我们更新信息。

我对 OP 的示例验收测试进行了一些更改，以反映我们为验收测试使用的一些新更改。本质上，这两个更改是：

导入，以及
在 acceptance 中使用 needs 常量

这应该可以解决您提到的大部分问题。您还可以利用此处的一些 needs 选项：

github.com/discourse/discourse

app/assets/javascripts/discourse/tests/helpers/qunit-helpers.js

711cd7c85


      
          const needs = {
            user(changes) {
              loggedIn = true;
              userChanges = changes;
            },
            pretender(fn) {
              addPretenderCallback(name, fn);
            },
            site(changes) {
              siteChanges = changes;
            },
            settings(changes) {
              settingChanges = changes;
            },
            mobileView() {
              mobileView = true;
            },
          };
          
          if (options.loggedIn) {

通读整个 qunit-helpers 文件也会非常有帮助！
