This document defines the localization testing mode for TODOS.phase-72.72.11.2.14. The mode cycles through all locales rapidly and takes a screenshot of each localized screen in every language. Its automation goal is to cycle through all locales and screenshot each screen with deterministic output paths.

The tracked contract is V2/ue/Content/Localization/V2/LocalizationTestingMode_V2_Contract.json. The generated capture plan is V2/ue/Content/Localization/V2/Testing/LocalizationTestingModePlan_V2.json, with summary coverage in V2/ue/Content/Localization/V2/Testing/LocalizationTestingModeReport_V2.json.

Capture Mode#

V2LocalizationTestingModeCapture is the native capture commandlet named by the plan. The plan reuses localized screen targets from ContextScreenshotManifest_V2.json, then creates one capture job per launch locale and per localized screen.

Each job records:

  • locale and screen ID;
  • FInternationalization::SetCurrentCulture as the culture switch API;
  • output path under V2/ue/Saved/LocalizationTesting/<locale>/;
  • -FastLocaleSwitch=1 for rapid locale cycling;
  • -ScreenshotEveryScreen=1 so every localized screen has evidence.

The generator restores the source locale after the run, waits two Slate ticks before capture, and bounds each locale pass to three seconds in the plan.

Validation#

V2/ue/Tools/generate-v2-localization-testing-mode.py builds the deterministic locale/screen matrix. V2/ue/Tools/check-v2-localization-testing-mode.py validates that all launch locales are covered, every localized screen gets a screenshot job in each language, fast switching is enabled, deterministic output is current, CI/Horde wiring exists, and the phase-72 checklist is updated.
