QUESTION
The documentation of coverage.py says that Many people choose to use the pytest-cov plugin, but for most purposes, it is unnecessary. So I would like to know what is the difference between these two? And which one is the most efficient ?
Thank you in advance
...ANSWER
Answered 2022-Mar-08 at 00:46pytest-cov uses coverage.py, so there's no different in efficiency, or basic behavior. pytest-cov auto-configures multiprocessing settings, and ferries data around if you use pytest-xdist.
QUESTION
I'm working on rewriting the test suite for a large application using pytest and looking to have isolation between each test function. What I've noticed is, multiple calls to commit inside a SAVEPOINT are causing records to be entered into the DB. I've distilled out as much code as possible for the following example:
init.py
...ANSWER
Answered 2022-Feb-23 at 17:04With the help of SQLAlchemy's Gitter community I was able to solve this. There were two issues that needed solving:
- The
after_transaction_endevent was being registered for each individual test but not removed after the test ended. Because of this multiple events were being invoked between each test. - The
_dbbeing yielded from thedbfixture was inside the app context, which it shouldn't have been.
Updated conftest.py:

For one python project, I want to ship a data file with the package. Following various (and partially contradictory) advice on the mess that is Python package data, I ended up trying different things and got it to work locally on my machine with the following setup.
My setup.cfg contains, among other things that shouldn't matter here,
ANSWER
Answered 2021-Nov-24 at 20:32You almost did it right, try slightly update your MANIFEST.in to any of the following examples:
include src/lexedata/data/*.ziprecursive-include src/* *.ziprecursive-include **/data clics3-network.gml.zip
As you can find in docs include command defines files as paths relative to the root of the project (that's why first example starts from src folder)
recursive-include expect first argument being as dir-pattern (glob-style), so it is better include asterisks

QUESTION
I'm trying to use pip-compile to build my requirements.txt file and I get the following error.
...ANSWER
Answered 2021-Sep-21 at 21:49The error comes from pip-tools trying to access the editable attribute on the class ParsedRequirement, whereas the correct attribute name on that class is is_editable. With previous versions of pip, the object at ireq were of type InstallRequirement, which does have the attribute editable.
Try pip==20.0.2; that seems to be the last version that returned InstallRequirement instead of ParsedRequirement from the relevant method (parse_requirements).

I am looking at an html coverage report generated by pytest-cov and I wonder if I can find which tests have invoked a particular line (which test covered a particular line).
...ANSWER
Answered 2021-Sep-17 at 14:19Coverage.py includes a feature called "contexts" which can easily be used to annotate results with test names: https://coverage.readthedocs.io/en/latest/contexts.html

QUESTION
I'm having issues testing my package with pytest and tox. When attempting to run both I receive ModuleNotFoundError. Pytest does find test_hello.py but fails immediate on trying to import my package for the test.
I am using PyCharm IDE which automatically sets up a pipenv environment for my project. I am using the terminal shell (Powershell instance) within PyCharm to run pytest / tox / pip commands.
I've tried running pytest with and without pip installing my package first: pip install -e . Both yields the same ModuleNotFoundError result.

Install pytest-cov
You can use pytest-cov like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
