I can't quite get the tests to run on my machine.

I'm running macOS 12.1 with Python 3.9.10 and 3.10.1 built via pyenv.

Here's the output of python setup.py test on 3.9.10:

Hi @ezarowny

Thanks for the PR!
I understand you want to add tests, but you have an issue with running the tests suite locally. Sorry for the confusion but I can help you with it!

First, blinker is not distributed as a wheel package and therefore setuptools tries to build the package. For that to happen you must install the wheel package.[1]

Second, I don't think PyEnv supports CPython 3.9.10 at the moment. The last version supported is 3.9.9 added in v2.2.1.

Here is a list of all the steps required to run the test suite with Python provided by PyEnv and virtualenv (you can tune it to your taste):

git clone https://github.com/rollbar/pyrollbar
cd pyrollbar

pyenv install 3.9.9
pyenv virtualenv pyrollbar-py3.9
pyenv local pyrollbar-py3.9

pip install wheel

python setup.py test

Finally, since Python 2 is no longer supported, Python 3.10 has removed the Python 2 backward compatibility layers.
Therefore Pyrollbar does not support Python 3.10 at the moment (it's on our roadmap).

[1] We are aware that this is not the best solution. We plan to refactor test management and package builder.

[ezarowny]

@bxsx got the tests running. Thanks!

[bxsx]

Great job @ezarowny 👍
Thanks for the contribution!

[mjhanke]

Can you guys release a version with this fix?

[danielmorell]

Yes. I just got access to our PyPI package. I will work on this.

[brettdh]

@danielmorell any updates? Just got bit by #399 today.

[danielmorell]

@brettdh I am working on resolving some issues with our CI test suite. Once those are resolved, I will get a release published to PyPI. It should happen today.

[brettdh]

@danielmorell just another check-in, as I lost some time to this again today.

[danielmorell]

Sorry about the delay! Almost there see #409.

[danielmorell]

Version 0.16.3 has been published to PyPI https://pypi.org/project/rollbar/. Again, sorry that took longer than expected!

[brettdh]

Thanks!
