OPTIMIZE YOUR PRODUCT FOR ANY LOCATION IN THE WORLD!
Location testing is a technique where the behaviour of software is tested in a specific location. By doing this, your software is appropriated to the language and culture of that particular region. For example, if the product were made in Switzerland, then the location testing would ensure that it is customized for the swiss culture. It will ensure that the UI, default language, documentation, date and time format are designed to fit the swiss culture.
The significant areas of focus in localization testing are content and UI. Only the local version of your product is put through localization testing.
