Automated testing of Lightning Web Components?

Personally, I struggled to get value out of the Lightning Testing Service and felt it was very limited compared to e.g. Angular Testing. Working for an ISV, automated testing is key to keeping components working for both old and new customers.



Does anyone have information about testability of the Lightning Web Components?

          Testing for LWC is implemented in Jest. These can be run locally to your org, or even enabled to run in "watch" mode to give you instant feedback while you code.



          From the docs, LWC testing enables you to




          • Test a component in isolation

          • Test a component's public API

          • Test basic user interaction with a component

          • Verify the DOM output of a component

          • Verify that events fire when expected


          There are a number of tests implemented in the e-bikes sample app in the sample app gallery.



          You can also read about it in the developer guide. Until it is updated for prerelease, you'll have to login to a pre-release org, and then go to the url:



          https://[your.org.domain]/docs/component-library/documentation/lwc/lwc.testing

          Accessing regular linux commands in Huawei's Dopra Linux

          4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset.

The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell".
