How do I run tests?

The test environment loads the built development output (not bundled nor minified) dist/src/index.html into jsdom.

# Commands support file filter
<pm> run testin-nutin           # build, then run once
<pm> run testin-nutin:watch     # build once, then re-run on file changes
<pm> run testin-nutin:coverage  # run and outputs coverage.
<pm> run testin-nutin:verbose   # run and log each test suite and test as it runs
