The goal of globalization testing is to detect potential problems in application design that could inhibit globalization. It makes sure that the code can handle all international support without breaking functionality that would cause either data loss or display problems. Globalization testing checks proper functionality of the product with any of the culture/locale settings using every type of international input possible.
Proper functionality of the product assumes both a stable component that works according to design specification, regardless of international environment settings or cultures/locales, and the correct representation of data.
