FAQPage Schema

How do I identify which tests to run based on recent code changes?▼

To identify impacted tests from code changes, you can use heuristic-based impact analysis. This approach predicts affected test files by analyzing changed source file paths, streamlining CI processes and reducing unnecessary test executions.

What is heuristic-based impact analysis for testing?▼

Heuristic-based impact analysis is a method to forecast impacted tests from code modifications. It estimates dependencies between changed source files and test files to reduce testing time during CI processes.

How do I perform pre-merge risk triage for a code review?▼

Perform pre-merge risk triage by providing the list of changed file paths and testing commands to an impact predictor. This identifies critical tests to run and highlights potential risks before merging into main branches.

Can I streamline CI processes by predicting impacted test files?▼

Yes, you can streamline CI processes by predicting impacted test files. Estimating which tests are affected by code modifications allows development teams to execute only necessary tests, significantly reducing testing time.

Does impact analysis require specific testing frameworks to predict affected tests?▼

Impact analysis does not mandate specific testing frameworks. It operates by taking changed file paths and your existing testing commands as inputs to forecast impacted tests, making it adaptable across different environments.

What are the limitations of using heuristics for test impact analysis?▼

Using heuristics for test impact analysis provides an estimation rather than absolute precision. While it effectively reduces unnecessary test executions, heuristic methods may occasionally miss edge-case dependencies compared to comprehensive test suites.
