An example of writing unit tests for Svelte with Svelte Testing Library and jest-transformer-svelte
Install the dependencies...
cd testing-svelte
yarn install...then start Rollup:
yarn devNavigate to localhost:5000. You should see your app running. Edit a component file in src, save it, and reload the page to see your changes.
By default, the server will only respond to requests from localhost. To allow connections from other computers, edit the sirv commands in package.json to include the option --host 0.0.0.0.
