Installation

Requirements

Python	3.11, 3.12, or 3.13
pytest	8.0 or later
Anything else	Nothing. The plugin has no dependency beyond pytest.

Every combination of those Python and pytest versions is exercised in CI, serially and under pytest-xdist, so the support claim is evidence rather than intent.

From conda (uibcdf channel)

The published package lives on the UIBCDF Anaconda channel:

conda install -c uibcdf pytest-receptor

From PyPI

The package is on PyPI. Its metadata declares pytest’s pytest11 entry point and Framework :: Pytest classifier, so installation makes pytest discover it automatically:

pip install pytest-receptor

The official pytest plugin list is generated from PyPI project names beginning with pytest- or pytest_; it is informational rather than an endorsement.

From source

git clone https://github.com/uibcdf/pytest-receptor.git
cd pytest-receptor
pip install -e .[dev]

Optional extra

tiktoken is used by --receptor-stats to count tokens exactly. Without it the flag still works and falls back to a labelled four-characters-per-token approximation.

pip install tiktoken

Installing it changes nothing

The default profile is human, and human registers no plugin at all — plain pytest produces output byte-identical to not having the receptor installed.

This matters in a shared environment: you can install it for yourself, or for an agent, without altering what anyone else sees. A regression test asserts the byte-for-byte equivalence.

Removing it

conda remove pytest-receptor   # or: pip uninstall pytest-receptor, if installed from source

Nothing is left behind except .pytest_cache/d/receptor/, which you can delete.
