Stabilization Features

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.
