Localization and Language Testing
Everything you need to know about localization testing
What is localization?
Localization is the process of customizing a software application that was originally designed for a domestic market so that it can be released in a specific foreign market. The process of localizing can be complex – applications need to be modified for locale-specific resources such as text, images, documents. currency, and more.

Do I need to test localization?
Localization, while important for global reach, introduces a substantial risk of bugs escaping into production. Common issues with localization include: broken functionality, untranslated text, text overlap and overflow, layout corruption, oversized windows & dialogs, and inadequate fonts.
