test/commands are not tested on CI

[tricknotes]

Since 3a1948c, tests under tests/commands are not tested via $ npm run test.
The following diff enables tests, but it seems there are some failing tests...

Good pick. Do you rather feel like opening another PR or include it in #789 ?

If when reenabling ignored tests, it reveals that some were broken, a separate PR is probably best.

My guess if that the entire test suite should be revisited, probably refactored, but it is not my strongest point.

Thanks for your comment, @PopGoesTheWza
I'll make another PR.
