    Preparing for Upgrade to Yokohama

    • Review and complete pre- and post-upgrade tasks specific to ATF before proceeding with the Yokohama upgrade.
    • Use provided quick start tests from the ServiceNow AI Platform® to validate your instance after configuration changes or upgrades. These tests run successfully only on base systems with default demo data.
    • To test instance-specific data, copy quick start tests and customize them with your own data.

    Key Features Introduced in Yokohama

    • Reusable Tests: Modularize test design by creating reusable tests which can be invoked across multiple tests, reducing duplication and maintenance effort.
    • New Reusable Test test step category allows easy access to reusable tests.
    • Reusable Input and Output Variables: Facilitate data transfer between test steps within reusable tests, improving test modularity and data management.

    Activation and Configuration

    • ATF is active by default as part of the ServiceNow AI Platform.
    • The system property snatf.runner.enabled is disabled by default to prevent accidental test execution in production. Enable it only in non-production instances.
    • To leverage quick start tests for specific applications, activate the corresponding application plugins.
    • Enable the ATF Test Generator and Cloud Runner store app content pack by setting snatf.runner.enabled to True.

    Browser and Platform Requirements

    • ATF supports running tests exclusively from desktop browsers; tests cannot be executed from tablets, mobile browsers, or mobile UI.
    • Some desktop browsers may require additional configuration for ATF compatibility.
    • Test design has limited support on tablets; notably, adding new custom UI test steps is not supported on tablet devices.

    Additional Notes

    • No features were removed, deprecated, or changed between Xanadu and Yokohama releases.
    • No updates related to accessibility or localization were introduced in Yokohama.
    • Using ATF can significantly reduce manual testing effort by enabling test reuse, scheduling test suites, rolling back test data post-execution, and expanding coverage with custom test steps.
