Testing

Exercises

Inconsistency between API and database

You may notice that the API expects a JSON key called cost but the database uses one called price. This currently leaks out to the API consumer in responses. Write helper functions that convert between the two formats and use them in db.clj.

Ensuring keys are present

Another quirk of the interaction between the database library and JSON API is the treatment of optional keys. We want to be able to leave the key off in the JSON API but the DB library expects an explicit null. The current code does this somewhat hackily; write a helper function that ensures a given key is present in the map, with a nil value if it's absent, then use it in db.clj.

Test the damage and cost fields

Right now the tests only check the returned name field on response bodies. Check damage and cost too

Test the optional field

The tests currently don't pass the optional durability field. Add a new test that uses it.
