Logging trouble with pytest

[6b6279]

Hello,

I have a project where I utilize PyO3 and I have recently started implementing unit tests for the project with pytest. The library itself has many debug! messages it emits, which I would like to take a look at when one of the unit tests fail. Normally, I would use the RUST_LOG envvar to enable the printing of debug! messages. I have tried running pytest with RUST_LOG=debug but that has sadly not helped. I then tried binding pyo3-log and use that as my logger; that also didn't work, even after calling pytest explicitly with --log-level=debug. I initialize the logger in the respective #[pymodule] block of my library, I have also ensured that the code where I bind the logger is covered. I am unsure what's wrong because RUST_LOG was sufficient (to reveal debug! messages) before I started using pytest.

I would highly appreciate any tips to get logging to work with pytest. Thanks in advance!

I have had and over come this exact problem in a variety of ways. Can you provide code examples?

Hi, I am not exactly sure what happened, but the issue solved itself after a few days. Maybe I was mistyping the environment variable repeatedly, or maybe I was in a virtenv which somehow broke something? env RUST_LOG=debug and --log-level=debug (together) did it for me.
