From 9049d4d6b39ac2d7aed07f2b6873878794265ed8 Mon Sep 17 00:00:00 2001 From: Hermes Bot Date: Sat, 2 May 2026 19:45:54 +0000 Subject: [PATCH] test(bootstrap): skip venv.EnvBuilder.create() in fail-loud test MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The test_ensure_python_fails_loudly_when_no_interpreter_can_import_agent test was passing locally but failing on CI runners because: 1. CI runners don't have REPO_ROOT/.venv/bin/python on the filesystem 2. The function path on missing venv calls venv.EnvBuilder(with_pip=True).create() 3. That internally calls subprocess.check_output() — a different code path than the monkey-patched bootstrap.subprocess.run, which only stubs run(). 4. CI fails with: AttributeError: NoneType has no attribute stdout The behavior under test is "what happens when no interpreter can import both WebUI deps and the agent" — NOT the venv-creation path. So we sidestep EnvBuilder by setting REPO_ROOT to tmp_path with a pre-existing .venv/bin/python file. The venv-existence check passes, EnvBuilder is skipped, the stubbed _python_can_run_webui_and_agent returns False on the final check, and the expected RuntimeError fires.
