How can I run unit test in polymer/test/unit/***.html

[hexiaoting]

I'm new to polymer, I donot know how to run unit test in this repo.
When I open these ***.html files with chrome directly, nothing showed.
Any advice?
Is there any document?

Hi @hexiaoting. There are instructions for running the unit tests here:

https://github.com/Polymer/polymer/blob/master/CONTRIBUTING.md#unit-tests

I'm not sure when those instructions were last updated--please let us know if they don't work for you.

If you're creating a new project from scratch, I'd recommend starting with LitElement instead.

@arthurevans thank you.
I follow the above link to run test:

(jupyter-dev) [root@hwtnode polymer]# yarn install

(jupyter-dev) [root@hwtnode polymer]# polymer serve --npm -H 0.0.0.0 -p 15130
info:	Files in this directory are available under the following URLs
      applications: http://0.0.0.0:15130
      reusable components: http://0.0.0.0:15130/components/@polymer/polymer/

But still cannot access it sucessfully. The error message is

GET http://10.60.1.80:15130/@webcomponents/webcomponentsjs/webcomponents-lite.js net::ERR_ABORTED 404 (Not Found)
GET http://10.60.1.80:15130/@polymer/iron-component-page/iron-component-page.js net::ERR_ABORTED 404 (Not Found)

The file "webcomponents-lite.js" doesnot exist on node_modules.
The file "iron-component-page.js" exists with the path:
node_modules/@polymer/iron-component-page/iron-component-page.js

Can you help me ?
