Christian C. Salvadó 83a6a6ea32 [ENHANCEMENT] Properly configure eslint to work with jest (#988)
* chore: make aware eslint that we use jest

By setting up the jest environment, we no longer need to declare the
'test' global in the configuration.

* chore: don't need to import expect, it's a jest environment global

* chore: don't need to import expect when creating undefined test
