Case
- Goal
- Navigate JSON.dump signature mismatches, JSON.load and symbolize_names addition conflicts, IO stream type rejections in JSON.parse, and custom object_class iterative mutation protocols HOW
- Packages
- json 2.9.1
- Environment
- ruby
- Created

Contract
- assert JSON.parse rejects IO streams with TypeError while JSON.load accepts them directly
- assert JSON.load with symbolize_names as second positional arg treats it as proc and silently leaves String keys
- assert JSON.load with symbolize_names as options conflicts with implicit create_additions and raises ArgumentError unless create_additions is false
- assert JSON.dump rejects kwargs and treats non-IO second arguments as limit or raises NoMethodError
- assert JSON.parse with object_class and array_class instantiates via arity-zero new and populates iteratively via []= and <<
- assert create_additions instantiates classes defining json_create matching JSON.create_id and leaves others as Hash
- assert freeze: true in JSON.parse deeply freezes containers and string keys and values
