What it is and what it does
Pytest-logger extends pytest with structured logging capture for individual named loggers. Instead of pytest's built-in log capture, it lets you configure which loggers to monitor, at what level, and routes their output to both stdout (during test runs) and to separate files organized by test and logger name in a session directory. You set it up via pytest hooks in conftest.py, naming the loggers you care about and their default output levels, then control which loggers appear during a test run using command-line options like `--log foo,bar.debug`.
The plugin is useful when your code or test fixtures use Python's standard logging module and you want fine-grained control over which log streams appear in test output and where they're stored. It organizes logs by test and logger name on disk, making it easy to review detailed logs for specific tests without cluttering the main test output.
Use it for
- Debugging test failures by reviewing per-logger log files organized by test name and logger
- Selectively enabling verbose logging for specific loggers during test runs via command-line flags
- Capturing logs from library code and fixtures without polluting the main pytest output stream
- Archiving test logs on a per-logger basis for post-test analysis and troubleshooting
