  • Internationalization & Localization Testing1. What is internationalization & Localization?Internationalization and localization are means of adapting computer software to different languages, regional differences and technical requirements of a target market.Internationalization is the process of designing a software application so that it can be adapted to various languages and regions without engineering changes.Localization is the process of adapting internationalized software for a specific region or language by adding locale-specific components and translating text. © 2011 LogiGear Corporation.

  • Internationalization & Localization Testing The distinction between internationalization and localization is subtle but important. Internationalization is the adaptation of products for potential use virtually everywhere, while localization is the addition of special features for use in a specific locale. Internationalization is done once per product, while localization is done once for each combination of product and locale. The processes are complementary, and must be combined to lead to the objective of a system that works globally © 2011 LogiGear Corporation. All Rights Reserved
  • Internationalization & Localization Testing Focal points of internationalization and localization efforts include:  Language o Computer-encoded text  Alphabets/scripts; most recent systems use the Unicode standard to solve many of the character encoding problems.  Different systems of numerals  Writing direction which is e.g. left to right in German, right to left in Persian, Hebrew and Arabic  Spelling variants for different countries where the same language is spoken, e.g. localization (en-US, en-CA) vs. localisation (en-GB, en-AU)  Text processing differences, such as the concept of capitalization which exists in some scripts and not in others, different text sorting rules, etc.  Plural forms in text output, which differ depending upon language o Input  Enablement of keyboard shortcuts on any keyboard layout o Graphical representations of text (printed materials, online images containing text) o Spoken (Audio) o Subtitling of film and video © 2011 LogiGear Corporation.

  • Internationalization & Localization Testing Focal points of internationalization and localization efforts include:  Culture o Images and colors: issues of comprehensibility and cultural appropriateness o Names and titles o Government assigned numbers (such as the Social Security number in the US, National Insurance number in the UK, Isikukoo in Estonia, and Resident registration number in South Korea.) and passports o Telephone numbers, addresses and international postal codes o Currency (symbols, positions of currency markers) o Weights and measures o Paper sizes © 2011 LogiGear Corporation. All Rights Reserved
  • Internationalization & Localization Testing Focal points of internationalization and localization efforts include:  Writing conventions o Date/time format, including use of different calendars o Time zones (UTC in internationalized environments) o Formatting of numbers (decimal separator, digit grouping) o Differences in symbols (e.g. quoting text using double-quotes (" "), as in English, or guillemets (« »), as in French).  Any other aspect of the product or service that is subject to regulatory compliance © 2011 LogiGear Corporation.

  • Internationalization & Localization Testing2. Why do we test about Internationalization &Localization?Software is often localized by translating a list of strings out of context, and thetranslator may choose the wrong translation for an ambiguous source string.Technical terminology may become inconsistent if the project is translated byseveral people without proper coordination or if the translator is imprudent.Literal word-for-word translations may sound inappropriate, artificial or tootechnical in the target language.Untranslated messages in the original language may be left hard coded in thesource code.Some messages may be created automatically at run time and the resultingstring may be ungrammatical, functionally incorrect, misleading or confusing.Software may use a keyboard shortcut which has no function on the sourcelanguages keyboard layout, but is used for typing characters in the layout ofthe target language. © 2011 LogiGear Corporation.

  • Internationalization & Localization Testing2. Why do we test about Internationalization &Localization?Software may lack support for the character encoding of the target language.Fonts and font sizes which are appropriate in the source language, may beinappropriate in the target language; for example, CJK characters may becomeunreadable if the font is too small.A string in the target language may be longer than the software can handle.This may make the string partly invisible to the user or cause the software tocrash or malfunction.Software may lack proper support for reading or writing bi-directional text.Software may display images with text that wasnt localized.Localized operating systems may have differently-named system configurationfiles and environment variables and different formats for date and currency. © 2011 LogiGear Corporation.

  • Internationalization & Localization Testing2. Why do we test about Internationalization &Localization? To avoid these and other localization problems, a tester whoknows the target language must run the program with all thepossible use cases for translation to see if the messages arereadable, translated correctly in context and dont causefailures. © 2011 LogiGear Corporation.

  • Internationalization & Localization Testing3. Example of test cases and bug: o Test cases: Description: Verify that “Next Plan”, “Change Plan”, “Print Preview” buttons are displayed with Chinese after switching browser language into Chinese Step: 1. Open browser and change language into Chinese 2. Navigate www.identifix.com website 3. Create new vehicle 4. Go to Maintenance tab 5. Observe “Next Plan”, “Change Plan”, “Print Preview” button Expected Result: The name of “Next Plan”, “Change Plan”, “Print Preview” button change to Chinese © 2011 LogiGear Corporation.

  • Internationalization & Localization Testing4. Tips and Tricks − Prepare a suitable test environment for testing applications − Follow the correct translation − Begin testing with static elements − Pay attention to the controls, and error messages − Ensure that data entry can be done in terms of localization − Do not forget the national and regional particularities © 2011 LogiGear Corporation.
