Analyze test redundancy using coverage data.

recov: Optimize Test Suites & Speed Up CI/CD

Motivation

Modern software projects often accumulate large test suites, but not all tests contribute unique value. Redundant tests slow down CI/CD pipelines, waste compute resources, and obscure true coverage gaps. recov helps you identify and remove tests that do not contribute unique coverage, so you can:

• Speed up CI/CD by running only the essential tests
• Reduce maintenance by focusing on meaningful tests

Features

• Detects redundant tests using coverage data (lines and branches)
• Fast, in-memory analysis with DuckDB and PyArrow
• Rich terminal output for easy review
• Works with pytest-cov and Coverage.py
• CLI and Python API

Quickstart

1. Run your tests with coverage contexts:

   pytest --cov=src --cov-context=test --cov-branch --cov-append
   

2. Analyze for redundant tests:

   uvx recov  # or use the CLI entrypoint
   

Usage

• By default, recov analyzes line coverage. Use --with-branches to require branch coverage.
• Results show which tests are redundant (their coverage is fully covered by other tests).
• Remove or refactor redundant tests to optimize your suite and speed up CI/CD.

Source File Filter

By default, rcov filters source files using a hard-coded substring (src/recov). Update this filter in src/recov/__init__.py line 177 to match your project's source path (e.g., src/yourproject).

Development & Contributing

Contributions welcome: open issues or PRs to improve detection, performance, or usability.
