This pull-request contains an example how inline-snapshot can be used with different snapshots for different pydantic versions.

The following code can be used to create different snapshots for each pydantic version (pytest has to be run with both pydantic version).

assertsome_value==snapshot_pydantic(v1=snapshot(),v2=snapshot())

both snapshots will be created (see example in the pull-request).

I would be interested if this approach looks useful to you, or if you prefer the current IsDict(...)|IsDict(...) pattern for some reason.

The next version of inline-snapshot will support things likesnapshot_pydantic() inside of snapshots. which will make the following code work:

assertresponse.json()==snapshot(        {"openapi":"3.1.0","info": {"title":"FastAPI","version":"0.1.0"},"paths": {"/items/": {"get": {"summary":"Read Items","operationId":"read_items_items__get","parameters": [                            {"name":"session_id","in":"cookie","required":True,"schema": {"type":"string","title":"Session Id"},                            },                            {"name":"fatebook_tracker","in":"cookie","required":False,"schema":snapshot_pydantic(v1=snapshot(),v2=snapshot()),                            },

Thank you for using inline-snapshot 😃.
