Stabilization Features
Lastest includes 12 stabilization features to prevent flaky tests and ensure consistent screenshots across runs and operating systems.
Network Idle Waiting
Wait for network activity to settle before capturing screenshots. Prevents capturing pages mid-load.
DOM Stability Detection
Wait for DOM mutations to stop before screenshot. Ensures dynamic content has finished rendering.
Timestamp Freezing
Replace Date.now() and new Date() with fixed values. Prevents timestamps from causing false positives in visual diffs.
Random Value Seeding
Seed Math.random() for consistent outputs. Any randomized UI elements (avatars, colors, order) will be deterministic.
Third-Party Blocking
Block third-party domains with a configurable allowlist. Prevents ads, analytics, and external content from affecting screenshots. Can also mock external images.
Font Loading Wait
Wait for webfonts to load before capture, or disable them entirely. Prevents screenshots with fallback fonts.
Loading Indicator Hiding
Auto-hide spinners and loading states with custom selectors. Add CSS selectors for loading indicators in your app.
Cross-OS Consistency
Bundled fonts and Chromium flags for identical screenshots across operating systems. Addresses differences between Linux, macOS, and Windows rendering.
Burst Capture
Multi-frame instability detection: take N screenshots and compare them for stability before saving. If screenshots aren't consistent, the page hasn't stabilized.
Auto-Mask Dynamic Content
Automatically detect and mask timestamps, UUIDs, and relative times before comparison. No manual ignore region configuration needed for common dynamic patterns.
Page Shift Detection
Detect vertical content shifts (inserted/deleted rows) with fuzzy row matching. Distinguishes between actual changes and simple content insertions/deletions.
Text-Region-Aware Diffing
OCR-based two-pass comparison with separate thresholds for text vs non-text regions. Reduces false positives from font rendering differences.
Configuration
All stabilization features are configured in Settings > Stabilization. Each feature can be independently enabled or disabled.
