Localization testing

Localization testing is a part of software testing process focused on internationalization and localization aspects of software. Localization is the process of adapting a globalized application to a particular culture/locale. Localizing an application requires a basic understanding of the character sets typically used in modern software development and an understanding of the issues associated with them. Localization includes the translation of the application user interface and adapting graphics for a specific culture/locale. The localization process can also include translating any help content associated with the application.

Localization of business solutions requires that you implement the correct business processes and practices for a culture/locale. Differences in how cultures/locales conduct business are heavily shaped by governmental and regulatory requirements. Therefore, localization of business logic can be a massive task.

Localization testing checks how well the build has been translated into a particular target language. This test is based on the results of globalized testing where the functional support for that particular locale has already been verified. If the product is not globalized enough to support a given language, you probably will not try to localize it into that language in the first place!

You still have to check that the application you're shipping to a particular market really works and the following section shows you some of the general areas on which to focus when performing a localization test.

The following needs to be considered in localization testing:
* Things that are often altered during localization, such as the UserInterface and content files.
* Operating System
* Keyboards
* Text Filters
* Hot keys
* Spelling Rules
* Sorting Rules
* Upper and Lower case conversions
* Printers
* Size of Papers
* Mouse
* Date formats
* Rulers and Measurements
* Memory Availability
* Voice User Interface language/accent
* Video Content

It's also a good idea to check that everything you are going to distribute in a local market complies with the local laws and regulations.
