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 MyComponent from 'pathToComponent/MyComponent'
When i run the test i get:
Error loading test file: /test/example.test.js
TypeError: Failed to fetch dynamically imported module: http://localhost:9876/base/test/example.test.js
I have it on a github repo here: https://github.com/boguz/rollup-lit-redux, so you can take a better look if you need to see what other packages i have installed.
Any help is very appreciated. Thank you!
