| Sauce Visual Testing supports the various diffing engines, which are described below. | ||
| Our SDKs give you the ability to select a specific engine for each snapshot, if you don't want to rely on the default engine. | ||
|
|
||
|
|
||
| ## Balanced | ||
|
|
||
| The Balanced engine will soon be our default engine. | ||
| It support all features like selective diffing and provides great all around performance. | ||
| It is able to detect single pixel changes while ignoring barely visible rendering artifacts such as anti-aliasing or small color inaccuracies. | ||
|
|
||
|
|
||
| ## Simple | ||
|
|
||
| Our first engine. It is similar to the Balanced engine, but we specifically developed the Balanced engine to address some corner cases that the Simple engine didn't handle well. | ||
| We will support the Simple engine for the forseeable future, but we won't backport new features to it. | ||
| In particular, selective diffing is not available for the Simple engine. | ||
|
|
||
| We recommend using the Balanced engine instead of the Simple engine. | ||
|
|
||
|
|
||
| ## (Experimental) | ||
|
|
||
| We have am Experimental engine that is constantly changing and used for showcasing and troubleshooting. | ||
| Please don't use this engine in production. |

|
||
| In addition to website testing, Sauce Visual also supports testing of native mobile apps for Android and iOS with Appium. | ||
|
|
||
| In principal, the process is the same as writing a visual test for a website, except that instead of a website, an app needs to be specified in the capabilities. | ||
|
|
||
| Check out [our examples](https://github.com/saucelabs/visual-examples/) to see it in action. | ||
|
|
||
|
|
||
| ## Best Practices | ||
|
|
||
| When writing a visual test for mobile apps, we recommend the following | ||
| - Explicitly control "dark mode" / "light mode" before taking visual snapshots, so snapshots are either always taken in dark or light mode, but not mixed. | ||
| - Explicitly specify a single device and OS version for testing. You may run the same test suite on various devices, but don't use wildcards in device names (dynamic device allocation). | ||
|
|
||
|
|
||
| ## Limitations | ||
|
|
||
| The following features are not available for mobile app testing: | ||
| - Full page screenshots | ||
| - DOM capture and inspection | ||
| - [Selective diffing](./selective-diffing.md) | ||
