I mixed hyperapp with hpyerscript.. My bad

In terms of "heavy", it's actually a problem with node's package management. Once I include test frameworks as dev dependencies, there's a high chance of installing my package will get the test framework together with it's whole bunch of dependencies installed as well - very unnecessary and time consuming.

No problem, the JS ecosystem is so full that there is a lot of naming overlap.

Nothing should be stopping you from just making a test file, you don't _have_ to use a framework. NodeJS even comes bundled with https://nodejs.org/api/assert.html .
