pytest-incremental

What it is and what it does

pytest-incremental is a pytest plugin designed to accelerate test feedback loops during development. It tracks file modifications between test runs and uses that information to reorder test execution and skip tests that are unlikely to be affected by recent changes. This allows developers to get faster feedback when running tests interactively, rather than waiting for the entire test suite to complete each time.

The plugin analyzes your project structure to understand dependencies between code and tests, then uses this analysis along with file change detection to make intelligent decisions about which tests to run and in what order. However, the package has been abandoned for 1938 days, with the last release in April 2021, raising concerns about compatibility with modern pytest versions and recent Python releases.

Use it for:

• Speed up local test-driven development by running only tests affected by recent code changes.
• Reduce feedback latency in development by prioritizing tests most likely to catch regressions.
• Optimize test execution order to fail fast on high-impact tests before running the full suite.
• Accelerate interactive development workflows where developers run tests frequently between code edits.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

pytest-incremental is a pytest plugin that speeds up test execution by analyzing project structure and file changes to reorder tests and skip unchanged ones.

No. The package is abandoned (last release April 2021, 1938 days without updates) and high install friction is reported. Compatibility with current pytest and Python versions is unverified. For modern incremental testing, consider actively maintained alternatives.

Install
