SteadyNode Features
Playwright synthetic testing for critical user journeys
Use isolated Playwright checks for important flows, with selector repairs suggested and verified when a page changes.
Test an outcome, not every click
Choose a short browser journey with a clear pass condition, such as reaching a critical page or receiving a confirmation in a test workflow. Stable assertions make failures easier to interpret and reduce maintenance.
Keep test identities and data isolated
Use dedicated test accounts and non-production data wherever possible. Avoid storing credentials in page content or screenshots, and make cleanup part of the test design when a flow creates records.
Pair browser checks with endpoint checks
A browser test can validate rendered content and interaction, while an HTTP check gives a lighter-weight availability signal. Use both selectively for workflows where a broken page has material customer impact.
Review selector repairs before applying them
When a locator times out but the document returned HTTP 2xx, SteadyNode can use a bounded, sanitized page structure to suggest a replacement and verify it in the sandbox. Auto-apply remains off unless you enable the policy for that journey.
Frequently asked questions
What should a Playwright synthetic test cover?
Prioritize a small number of stable, high-impact journeys such as navigation to a critical page or a test-only form submission.
Will selector healing rewrite a test automatically?
By default, no. When a locator times out on a healthy HTTP 2xx page, SteadyNode suggests a replacement selector, verifies it inside an isolated Playwright sandbox, and generates a code diff for 1-click review. If your team prefers hands-off maintenance, you can explicitly enable the Auto-Apply Verified Heals policy per journey so only 100% sandbox-verified fixes update the script automatically.
Can browser synthetics replace API uptime checks?
No. Browser checks exercise a user flow but cost more to run and maintain. Pair them with simpler endpoint checks for broader availability coverage.
