A new job builds the eight wheels with python -m build, as the release pipeline does, installs them and runs mypy --strict on tests/consumer/consumer.py. That file uses the public API of every package and pins representative return types with assert_type, so the job fails when a package loses py.typed, an export or a return type. Against wheels built from 37492f7, where microsoft#722 started, it reports 15 errors.

pip install --only-binary :all: for both installs in type-check-installed-wheels, so no dependency runs a setup script. Every dependency has a wheel on Python 3.10 to 3.15.

Vincent Biret (@baywet) the two remaining Sonar findings (locked versions) are the same rule that is open on main for the existing build and validation jobs (build.yml L51 and L91). Could you mark them as safe, or should this job pin with hashes? |

Overview
Last item in #722. A new CI job builds the eight wheels with
python -m build, as the release pipeline does, installs them and runsmypy --strictontests/consumer/consumer.py. That file uses the public API of every package and pins representative return types withassert_type. It runs on the same Python matrix as the other jobs and feedscheck-python-version-matrix.Related Issue
Closes #722.
Demo
Not needed for this change.
Notes
The job checks the installed wheels, not the source tree, so it sees what a consumer sees: a missing
py.typed, a name left out of__all__, or a return type that turns intoAny. Against wheels built from 37492f7, where #722 started, it reports 15 errors, the issue'sRetryHandlerOption().get_key()example among them. On main it reports none.Testing Instructions
