SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Analyzes test coverage data to identify untested code paths and guides teams on where to focus testing efforts to reduce risk and improve quality.

Core Features & Use Cases

  • Analyze coverage reports to highlight high-risk gaps and guide test prioritization.
  • Prioritize tests based on uncovered lines and branches, including edge cases.
  • Integrate with common Python tooling (pytest, coverage.py) to automate risk-informed test planning.

Quick Start

Run pytest --cov=<package> --cov-report=term-missing to generate a coverage report and identify untested code paths.

FAQPage Schema
How do I prioritize untested code paths using pytest coverage reports?

To prioritize untested code, run pytest with coverage support to generate a report identifying uncovered lines and branches. This analysis highlights high-risk coverage gaps to guide test planning and risk reduction efforts.

What is the best way to identify high-risk coverage gaps in a Python codebase?

Identifying high-risk coverage gaps involves analyzing coverage reports to highlight untested code paths. By interpreting uncovered line and branch data, you can prioritize tests based on risk and edge cases to improve quality.

Does coverage analysis work with Python projects of various sizes?

Yes, coverage analysis applies to software projects of various sizes, specifically focusing on Python codebases. It interprets coverage gap data to provide actionable recommendations for risk-informed test planning across different project scales.

How do I generate a coverage report to find untested lines and branches?

Generate a coverage report by running pytest with the coverage flags, such as --cov and --cov-report=term-missing. This produces output detailing uncovered lines and branches to guide your test planning.

Do I need pytest to analyze code coverage gaps?

You need a test runner with coverage support, such as pytest with the coverage.py plugin, to generate the necessary coverage data. The analysis then interprets this uncovered line and branch data to recommend actionable test planning.

When should I use coverage analysis for test planning?

Use coverage analysis when you need to reduce risk and improve quality by identifying untested code paths. It guides teams on where to focus testing efforts by prioritizing tests based on uncovered lines and branches.
