For a global user base, accurate localization is key. This test checks the quality of the app’s translations into various languages. The tester changes the device’s language to a supported non-English language (e.g., Spanish, German, Japanese) and then launches the MetaMask app. The entire UI, including buttons, menus, labels, and warning messages, should be translated. The test involves navigating through all major app features: creating a wallet, sending a transaction, using the browser, and checking settings. The translations must be accurate, culturally appropriate, and consistent throughout the app. Technical terms should be translated correctly to avoid confusion. Poor localization can lead to user errors and a frustrating experience. This test ensures the app is accessible and reliable for non-English speakers. The community often contributes to translations, and feedback on them can usually be provided through channels mentioned at metamask.
