UnsatisfiableError: The following specifications were found to be incompatible with a past
explicit spec that is not an explicit spec in this operation (sqlalchemy):

  - alembic[version='>=1.7.6'] -> sqlalchemy[version='>=1.3.0']
  - httpx[version='>=0.22.0']
  - psycopg2[version='>=2.9.3']
  - pytest-httpx[version='>=0.20.0'] -> httpx=0.22
  - pytest-httpx[version='>=0.20.0'] -> pytest=6

  - requests[version='>=2.27.1']
  - sqlalchemy-utils[version='>=0.38.2'] -> sqlalchemy[version='>=1.0']
  - sqlalchemy[version='>=1.4.31']

From this CHANGELOG entry it appears as though pytest 7 should be supported.

I’m pretty new to python package management, so I’m not sure if I’m doing something dumb. Also since we’re using conda-forge, I checked that artifact repository and I see 0.20 was uploaded 19 days ago, so I’m assuming they have the most up-to-date version.

If I switch from pytest>=7.0.1 => pytest>=6.2.5

Sorry responding a bit late but I can confirm conda/mamba seem happy to create environments with pytest 7 and pytest-httpx 0.20
