# This is a skeleton for testing models including examples of validations, callbacks,
# scopes, instance & class methods, associations, and more.
# Pick and choose what you want, as all models don't NEED to be tested at this depth.

# I'm always eager to hear new tips & suggestions as I'm still new to testing,
# so if you have any, please share!
