Tests fail: ValueError: option names {'--hypothesis-profile'} already added

[yurivict]

Initial Checks

• I have searched GitHub for a duplicate issue and I'm sure this is something new
• I have searched Google & StackOverflow for a solution and couldn't find anything
• I have read and followed the docs and still think this is a bug
• I am confident that the issue is with pydantic (not my code, or another library in the ecosystem like FastAPI or mypy)

Python, Pydantic & OS Version

Python-3.9
Pydantic-1.10.2
FreeBSD 13.1

Affected Components

• Compatibility between releases
• Data validation/parsing
• Data serialization - .dict() and .json()
• JSON Schema
• Dataclasses
• Model Config
• Field Types - adding or changing a particular data type
• Function validation decorator
• Generic Models
• Other Model behaviour - construct(), pickling, private attributes, ORM mode
• Plugins and integration with other tools - mypy, FastAPI, python-devtools, Hypothesis, VS Code, PyCharm, etc.

Looks like a problem with how you're using either hypothesis or pytest, not pydantic.

Might be worth asking on the hypothesis repo.

[yurivict]

I am not using hypothesis. I only run pytest on this repository.

[samuelcolvin]

Is hypothesis installed?

Something is adding the --hypothesis-profile command line option, twice.

[yurivict]

hypothesis is installed.
PyTest is used the same way as in many other Python projects.
The problem is still present in 1.10.4

[samuelcolvin]

Weird. My guess is that hypothesis is somehow installed twice or being initiated twice.

Maybe worth asking on the hypothesis issue tracker, or maybe @Zac-HD would be kind enough to reply here?

[lig]

closing this as there were no reproducible example provided here or on hypothesis issue
