WIP
Svelte 3 "User component" example from https://svelte.dev/examples#if-blocks
WIP: the code coverage seems to NOT map the source correctly for .svelte files. For example, the small file src/App.svelte shows so many statements ...
Even if the .svelte file generates lots of code, the back source transformation does not seem to map correctly at all.
Hmm, the numbers seem to be from the compiled JS code, not the original Svelte template code.
Use npm run e2e to run the test runner GUI
Also using fork bahmutov/rollup-plugin-istanbul because the original version was behind times and did not have dist published.
See rollup.config.js
