FAQPage Schema
How do I check if my pull request has enough test coverage for new code paths?

To check pull request test coverage, analyze new code paths and edge cases to identify gaps. The analyzer evaluates modified components, groups findings by regression risk, and suggests concrete test cases to ensure adequate coverage aligning with project standards.

What is risk-based prioritization for PR test cases?

Risk-based prioritization for PR test cases ranks suggested tests by regression impact and likelihood. This ensures critical components and high-impact edge cases are tested first, providing actionable recommendations aligned with project testing standards.

How do I generate test scenarios for edge cases in a modified pull request?

Generate test scenarios for edge cases by analyzing new functionality and potential regressions in the PR. The analyzer produces actionable recommendations including specific test cases and scenarios, grouped by risk to target insufficient test coverage.

Does automated code review work for finding missing tests in critical components?

Automated code review works for finding missing tests by analyzing PRs with changes to critical components. It identifies gaps in test coverage for new or modified code paths and suggests concrete tests to prevent regressions.

When should I apply quality assurance analysis to a pull request?

Apply quality assurance analysis to a pull request when introducing new functionality or changing critical components. This proactively identifies gaps in test coverage for edge cases and potential regressions before merging, ensuring code quality.

Can I align suggested test cases with my project's existing testing standards?

You can align suggested test cases with existing project testing standards by analyzing the PR's new code paths. The analyzer generates actionable test ideas and scenarios specifically tailored to match the established quality assurance conventions of the project.
