Tests!

[LeaVerou]

We have no tests. We need tests.

We could use htest.dev for the same reason it's used in Mavo.

[DmitrySharabin]

Do we expect to have a separate repo for the tests? Or can we have test.html (tests.html) inside the corresponding folder, e.g., tests for the helper functions are inside the functions folder?

[LeaVerou]

The latter, linking to htest.dev directly.
