cov-core
plugin core for use by pytest-cov, nose-cov and nose2-cov
Decision gist · record as of 2026-08-14
No. Do not install cov-core directly. The package is abandoned, its last release was in 2014-11-22, and it targets obsolete Python versions (2.4–3.1). Install it only if a modern coverage plugin explicitly requires it as a dependency. Even then, verify that the plugin itself is actively maintained and compatible with your Python version.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Package is abandoned and targets Python 2.4–3.1; compatibility with modern Python versions is not guaranteed.
- High install friction: the package is abandoned (last commit 2018-07-03, archived repository) and has not been released since 2014-11-22.
- It targets Python 2.4–3.1, which are long obsolete.

# Typically installed as a transitive dependency; direct import is not recommended.- Whether this package still functions on modern Python versions despite classifiers declaring only Python 2.4–3.1 support.
- Whether pytest-cov, nose-cov, or nose2-cov still depend on cov-core or have migrated to alternative backends.
What it is and what it does
cov-core is a library that provides the shared plugin infrastructure for coverage measurement across multiple test frameworks. It was designed to be used by pytest-cov, nose-cov, and nose2-cov rather than directly by end users. The package has been abandoned since 2014 and its repository is archived; it targets Python 2.4 through 3.1, versions that are no longer supported.
If you are installing cov-core, it is almost certainly as a transitive dependency of one of the coverage plugins listed above. Direct installation or use is not recommended. The package has no runtime dependencies, but its age and obsolete Python version support mean it is unlikely to work correctly on modern Python environments without significant compatibility issues.
Use it for
- As a transitive dependency when installing pytest-cov for coverage measurement in pytest test suites.
- As a transitive dependency when installing nose-cov for coverage measurement in nose test runners.
- As a transitive dependency when installing nose2-cov for coverage measurement in nose2 test runners.
