What is localization testing?

Localization testing is the process of verifying that a software product is correctly adapted to a specific language, region, and culture of the user. It includes:

• Checking the interface translation into the required language.
• Verifying the display of dates, times, currencies, and numbers according to local standards.
• Ensuring the correctness of address formats, phone numbers, and other local data.
• Checking for the absence of culturally inappropriate content.

For example, when localizing a website for Russia, it is necessary to verify that dates are displayed in the format DD.MM.YYYY, the currency is in rubles, and the text is translated accurately and without errors.
