We are excited to announce incorporating support for the W3C WebDriver protocol specification for real device tests using Appium.
At this time, Sauce Labs supports both JSON Wire Protocol (JWP) and W3C protocol in all currently supported Appium versions.
Note: The forthcoming Appium 2.0 release in 2022 will deprecate support for JWP.
Sauce Labs advises migrating your tests to W3C to take advantage of the upcoming Appium 2.0 features and functionalities.
Please find more information in our Knowledge Base article and in our docs on how to ensure your Appium real device tests are configured properly for W3C and are compatible with Sauce Labs.
