Test lit-element webcomponent with Karma

由 情到浓时终转凉″ 提交于 2021-01-29 11:28:51
问题 I am trying to create a blank project, like a template, using lit-html. I wanted to also add some testing capabilities, so i have been trying to get it to work with Karma. I can run a normal test, like an addition, without any errors, so i think Karma itself is running ok. but i can't run any test involving the webcomponent. I can't import the webcomponent! i am exporting the webcomponent with: export default class MyComponent ... and then on the test file i am importing it with: import

Why does web-component-tester time out in flight mode?

问题 I've got a basic web-component-tester project which works fine when I'm online. If I switch to flight mode, it seems to fail to connect to Selenium, and instead gives a largely useless error message after about 60s delay: "Error: Unable to connect to selenium". Edit 2 : I've narrowed the problem down in the following question, but I'd still like to know how to avoid it with web-component-tester: Why does NodeJS request() fail on localhost in flight mode, but not 127.0.0.1? (Windows 10) Edit :

Specify browser location for wct-local test

问题 The Polymer Starter Kit contains web-component-tester for unit testing your custom elements. In wct.conf.json you can specify the browsers to run the tests in. { "suites": ["app/test"], "plugins": { "local": { "browsers": ["firefox"] } } Unfortunately, when I launch the tests through gulp, wct is not able to find my local Firefox. I read at GitHub that wct uses launchpad to detect local browsers. Afaik, on a Windows machine, launchpad searches for Firefox in the default directory "C:\Program

How can I replace the server in Web Component Tester

问题 I have a project set up based around the Polymer Starter Kit, which includes Web-Component-Tester This project includes php server code which I would also like to test by writing tests to run in the browser which will utilise the PHP server code through Ajax Calls. This implies replacing the server that Web Component Tester is using ONLY when testing server side code. I hope to make a separate gulp task for this. Unfortunately, I don't understand the relationship between WCT, Selenium and

问题 I am trying to unit test a very simple web-component. I don'ty know what would be some of recommended tools for that. At this moment I am trying by using wct and I am facing some issue that I didn't find anyone facing same issue. That said, I am not sure if I choose an appropriated tool for my test or I am using it incorrectly. So, my straight question is: why I am getting "chrome failed to maximize" during such simple test.
