Internationalization, or localization, testing involves 
verifying that formats and structures that vary by locale 
are followed.We can test for any localization 
inconsistencies. We will follow the standards and formats
defined by the client, which often conform to a widely 
recognized regional standard such as metric vs. standard, 
date formats, number grouping/decimal formats, and time 
zone/format differences. The goal of internationalization 
testing is to confirm that the locale-specific formats and
standards are followed.

Hi Swaroop
 can u please be a brief..
i'm hearing this qution for the first time.
wht is localization tetsing and globalization testing?
globalization and internalization testing are same??
when we will do these tests??

Localization Testing
Localization translates the product UI and occasionally 
changes some initial settings to make it suitable for 
another region. Localization testing checks the quality of 
a product's localization for a particular target 
culture/locale. This test is based on the results of 
globalization testing, which verifies the functional 
support for that particular culture/locale. Localization 
testing can be executed only on the localized version of a 
product. Localizability testing does not test for 
localization quality. The test effort during localization 
testing focuses on:

•	 Areas affected by localization, such as UI and 
content
•	 Culture/locale-specific, language-specific, and 
region-specific areas

In addition, localization testing should include:

•	Basic functionality tests
•	Setup and upgrade tests run in the localized 
environment
•	Plan application and hardware compatibility tests 
according to the product's target region

The localization testing of the user interface and 
linguistics cover items such as:
•	Validation of all application resources
•	Verification of linguistic accuracy and resource 
attributes
•	Typographical errors
•	Consistency checking of printed documentation, 
online help, messages, interface resources, command-key 
sequences, etc.
•	Confirmation of adherence to system, input, and 
display environment standards
•	User interface usability
•	Assessment of cultural appropriateness
•	Checking for politically sensitive content

Internationalization is the process of designing and coding 
a product so it can perform properly when it is modified 
for use in different languages and locales. 

Localization (also known as L10N) refers to the process, on 
a properly internationalized base product, of translating 
messages and documentation as well as modifying other 
locale specific files. 

Assuming that there is not a separate base product for the 
locale, the localized files are installed at their proper 
location in the base product. This product is then released 
as a localized version of the product. 

Localizing a properly internationalized product in most 
cases should require no changes to the source code. 

Internationalization Testing
These pages contain the methodologies you will find useful 
for testing a product to ensure it has been properly and 
fully internationalized.

Localization ("L10N"), refers to the process of translating 
content and adapting products and applications to meet 
language and locale-specific requirements. 
Internationalization ("I18N"), refers to the process of 
designing products, applications, and content so they can 
be localized without requiring engineering changes.
