nose-py3
nose extends unittest to make testing easier - python3 version
Decision gist · record as of 2026-08-14
Yes, if you have an existing nose-based test suite that needs Python 3 support and you want to avoid rewriting tests for pytest. No, if starting a new project—pytest is the modern standard and actively maintained. The aging maintenance status and lack of recent updates mean this is best treated as a compatibility shim for legacy codebases rather than a foundation for new test infrastructure.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with no runtime dependencies.
- Maintenance status is aging—last commit was 2026-02-14 and the package has not been updated since 2025-12-05, though the repository remains active and not archived.

What it is and what it does
nose-py3 is a Python 3 fork of the nose testing framework that builds on unittest's capabilities. It automatically discovers tests in files and directories matching naming patterns like "test_*" or "*_test", then runs them with enhanced reporting—notably capturing and displaying stdout from failing tests for easier debugging.
The package is plugin-extensible, with built-in support for doctest, code coverage, profiling, and flexible test selection by attributes. It offers a middle ground between unittest's verbosity and pytest's modern approach, though it is no longer actively developed—the repository shows minimal recent activity despite being marked stable.
Use it for
- Run existing unittest-based test suites with automatic discovery instead of manual test collection
- Debug test failures by viewing captured print output without modifying test code
- Measure code coverage across a test suite using nose's built-in coverage plugin
- Migrate from older nose to Python 3 when the original nose no longer works with your Python version
