From 1da7dbfe239f4a3ea8482fd7d98112fd7d3eb795 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 13 Apr 2026 13:48:52 +0000 Subject: [PATCH 1/2] Add unit tests for `bionetgen.modelapi.runner.run` - Implemented tests using `unittest.mock` to stub out `BNGCLI` and `TemporaryDirectory`. - Added tests covering happy path (with out dir, without out dir) and exception flow. - Added a compatibility fix in `csimulator.py` and `utils.py` for Python 3.12, replacing `distutils` with standard library equivalents (`shutil`).
