I’m publishing a Python package.
It has dependencies a, b, c. It also has pytest as a dependency, defined in the group.dev as per poetry’s documentation.
However, I couldn’t find a conclusive answer for the following question:
When some installs my library with:
pip install my_library
Is pytest (defined in any group other than the main group, in this case dev) also installed? That would be very undesirable.
You can mention the dev dependency like this. It will not install the pytest. Reference
# rp_poetry/pyproject.toml (Excerpt)
[tool.poetry.dependencies]
python = "^3.9"
requests = "^2.26.0"
[tool.poetry.dev-dependencies]
pytest = "^5.2"
black = "^21.9b0"
poetry is may go to change the label of dev-dependencies in the future.
