FAQPage Schema
How do I automate regression testing for web applications after deploying new features?▼

Automated regression testing for web applications systematically explores affected pages using a headless browser to verify functionality and catch bugs before they reach production. It mimics user interactions to identify visual, functional, and performance issues.

What is diff-aware testing and when do I need it for feature branches?▼

Diff-aware testing is a mode that systematically targets only the affected pages of a web application based on feature branch changes. You need it to efficiently catch regressions and document UX issues without running a full application scan.

Can I run a quick smoke test on a web application to check basic functionality?▼

You can run a quick smoke test on a web application to rapidly verify basic functionality and identify critical visual or accessibility issues. This testing mode provides a structured report with health scores and evidence without deep exploration.

Does headless browser testing detect accessibility and performance issues?▼

Headless browser testing detects accessibility and performance issues by systematically exploring web applications and mimicking user interactions. It documents these problems alongside functional and UX bugs into a structured report with health scores.

What's the best way to document visual bugs and UX issues during web application testing?▼

The best way to document visual bugs and UX issues is through systematic web application testing that generates structured reports with evidence. This approach identifies problems across various testing modes and provides health scores for tracking quality.
