Mobile Native Testing
In addition to website testing, Sauce Visual also supports testing of native mobile apps for Android and iOS with Appium.
In principle, the process is the same as writing a visual test for a website, except that instead of a website, a mobile native app needs to be specified in the capabilities.
Check our examples to see visual for mobile native 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 yet available for mobile app testing:
Native full-page screenshots are currently in beta and may have unexpected behavior. Identified limitations:
- Slow screenshot capture
- 1 pixel shifts in the screenshot (iOS tablets only)
- Ignoring and clipping limited to elements within
scrollElement(iOS only) - Sticky elements missing at the bottom of the screen
- DOM capture is not available
