These tests set MOLTBOOK_API_KEY in the environment, but post_to_moltbook() reads the module-level MOLTBOOK_KEY that was captured at import time. As written, the tests can return early (no HTTP call) and still pass, and can also become environment-dependent. Set evangelist_agent.MOLTBOOK_KEY explicitly (or reload the module after setting env) and assert the expected client.post behavior to ensure you’re exercising the intended branches.

This test deletes MOLTBOOK_KEY from the environment, but the application uses MOLTBOOK_API_KEY to populate MOLTBOOK_KEY. To avoid confusion and to make the intent accurate, delete MOLTBOOK_API_KEY instead (and/or set evangelist_agent.MOLTBOOK_KEY explicitly, which you already do).

Suggested change

Nice direction overall, but I don't think the new suite is actually covering all of the branches it claims yet. Two blocking issues stood out while comparing the tests to evangelist_agent.py:

evangelist_agent.py captures MOLTBOOK_KEY = os.environ.get("MOLTBOOK_API_KEY", "") at import time. Several new tests in tests/unit/test_actions.py mutate the environment with monkeypatch.setenv("MOLTBOOK_API_KEY", ...) but do not patch evangelist_agent.MOLTBOOK_KEY. That makes the test outcome depend on whatever env was present when the module was first imported. In particular, test_api_failure_http_error and test_api_failure_exception can pass without ever exercising the HTTP-error/exception branch, because post_to_moltbook() returns early on the cached empty key before mock_client.post is called. Conversely, test_missing_api_key can become flaky if the runner imported the module with a real key already present.
The workflow tests that call both setup_beacon_mocks(...) and setup_bottube_mocks(...) are overwriting the same evangelist_agent.client object twice. The second helper wins, so run_once() is no longer talking to the Beacon mock when it reaches discover_agents_from_beacon(). That means tests like test_dry_run_complete_workflow / test_normal_run_with_agents are not really validating the combined Beacon+BoTTube discovery path even though the PR description claims broad end-to-end coverage.

I'd fix this by either (a) patching module-level constants like MOLTBOOK_KEY directly in the affected tests, or (b) refactoring production code to read env lazily. For the workflow tests, use a single client double that understands both Beacon and BoTTube URLs, or patch the discovery functions directly instead of stacking two helpers that both replace evangelist_agent.client.

Merged! Excellent expansion of the test suite — 1,549 lines, mock services for Beacon/BoTTube/Moltbook, proper fixtures and monkeypatching. Coverage jump is real.
