Overview of Localization Testing and what are its focus areas.

Localization is a process of customizing a software application that was originally designed for a domestic market so that it can be released in foreign markets. Localization testing checks the quality of a product's localization for a particular target culture/locale.

Areas of focus in Localization testing
- Localization testing should focus on the areas affected by localization, such as UI and content, culture/locale-specific, language-specific, and region-specific areas.
- The localized checklist includes spelling rules, sorting rules, upper and lower case conversions, printers, size of papers, operating system, key boards, text filters, hot keys, mouse, date formats, measurements and rulers, available memory.
- Localization testing should include basic functionality tests, setup and upgrade tests run in the localized environment and plan application and hardware compatibility tests according to the product's target region.
- Availability of drivers for local hardware.
- Encryption algorithms.
- Focus on customization that could not be automated through the globalization services infrastructure.
- The quality is not usually checked during localization testing.
- Validation and verification of applications, linguistic accuracy, and consistency checks can be purchased separately.
- Localized testing can weed out potential errors, before they are localized and correcting them becomes costly.
- The advantage of localized testing is that it saves time.
