recheck-web Chrome extension
Find subtle differences
When you have to play “spot the difference”, the Chrome extension will help you out and pin-point any changes. It is often helpful to ignore “Positioning”, as small changes will often result in most elements being “shuffled around”.
Work with animations
How do you diff moving animations? Can you even find the difference as a human?Well … recheck-web can. Try comparing this animation to this animation. And again, ignoring the positioning, recheck-web gives you just what you want, and even tells you that the animation starts 0.3 seconds later…
Better than pixel-diffing
Compare that to the current state-of-the-art in cross-browser and visual regression testing, which is (AI-enhanced) pixel-diffing:
- Pixel-diffing is indeterministic.
- Pixel-diffing gives both false positives (irrelevant changes) and false negatives (misses relevant changes).
- You can’t influence the (ai-based) filtering.
- Pixel-diffing just gives you a marked image, leaving the analysis up to you.
