How to Mock BugSnag Notify in Python
Use unittest.mock to simulate BugSnag notifications, verify calls, and test error handling without external dependencies.
import mock
bugsnag = mock.MagicMock()
def notify_error(message, severity="error"):
bugsnag.notify(message, severity=severity)
if __name__ == "__main__":
notify_error("Test error", severity="warning")
bugsnag.notify.assert_called_once_with("Test error", severity="warning")
print("Mocked BugSnag noti…How to Mock Poetry pyproject.toml Dependencies Sections in Python

"""Extract dependencies from a pyproject.toml style text."""
lines = text.splitlines()
sections = {
"dependencies": [],
"dev": [],
