library1.3.7pypypi✓ verified 21d ago

Nose extends unittest to make testing easier, providing a simpler test discovery and running mechanism. Its last major release was 1.3.7 in 2015, and the project is no longer actively maintained. Users are strongly encouraged to migrate to modern alternatives like pytest.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

run

✓ import nose nose.run()

TestCase

✓ from unittest import TestCase

This example demonstrates a basic Nose test case using unittest.TestCase. Nose discovers tests by default from files named `test_*.py` or classes/functions starting with `test_`. The common way to run tests is via the `nosetests` command line tool.

import nose from unittest import TestCase class MyTest(TestCase): def test_something(self): self.assertEqual(1, 1) if __name__ == '__main__': # To run this directly without the `nosetests` command: # nose.run() # For programmatic execution, typically you'd run from command line. print("Run with: nosetests") # Example of what `nosetests` would do if run programmatically: # nose.run(argv=['', '--verbose', __file__])

Known issues

breakingNose 1.3.7, the last released version, was developed primarily for Python 2. While it might partially function in some Python 3 environments, it is not officially supported and will likely encounter errors or unexpected behavior with modern Python 3 versions (3.6+).

fix

Migrate to a maintained testing framework like pytest or unittest (built-in). If forced to use Nose, ensure a Python 2.7 environment or use a specific `nose` fork with Python 3 support (e.g., `nose2`).

affects: <=1.3.7

deprecatedThe `nose` project is officially unmaintained and abandoned. Its GitHub repository prominently displays a warning encouraging users to switch to `pytest`. Expect no further updates, bug fixes, or security patches.

fix

Migrate testing suites to modern, actively maintained frameworks such as pytest or the built-in unittest module. These offer superior features, community support, and Python 3 compatibility.

affects: All versions

gotchaNose's test discovery mechanism (looking for `test_` prefixes in filenames, classes, and methods) can sometimes lead to unintended test execution or missed tests if not consistently applied. It also had specific rules for how it interacted with `__init__.py` files.

fix

Carefully review Nose's test discovery rules in its documentation. When migrating to other frameworks, understand their specific discovery rules, which might differ.

affects: All versions
