Usability testing It evaluates the ease of use of the system optional e Installation testing Testing to ensure if the product installation messages are displayed in a corresponding language when installing the application on a dedicated server 3 2 L10N Testing Localization testing is a language verification testing mainly focusing on the appropriateness of the translation in the following items e GUI context e Online help files e Error messages Dialog boxes e Tutorials Readme files e Documents such as User manual Installation guide Release notes etc Testing also involves in checking the GUI layout and making sure nothing is truncated in the UI and Correctness and consistency of the Error messages Note L10N testing is typically done by the native speaker of that specific language 4 118N testing Check List ei a Environment Setup Ensure the configuration hardware and software details from the Test Plan Source for the i18n testing environment 8 12 QAI Ensure the required native language English 1 2 version of O S is installed in Server boxes Ensure that the required locale is being 1 8 installed on the client machine Ensure that the required service pack oar Ensure the required Service Pack of native language version applied on O S For Windows Ensure that the required version of IIS Apache Tomcat is running on the server box where the Web Server is being installed Ensure that the corr2. and NNTP ActiveX controls to send receive and post encoded e mail or news messages The MIME ActiveX control supports RFC 822 plain messages MIME conformant Base 64 and Quoted printable Binhex as well as uuencode and uudecode It can encode or decode any of these file formats Courtesy Multipart Internet Mail Extensions Protocol ActiveX control for Microsoft windows Version 5 2 here by give a sample for Japanese test data to test the MIME part with various char sets for receiving messages receives messages in the application MIME is an internet standard for email messages which plays key role for i18n products Our product Supports both Iso 2022 jp and UTF 8 char sets MIME encoding and decoding char set for Japanese text is ISO 2022 jp and UTF 8 and the MIME format are Quoted Printable and Base 64 That is MIME would use a char set ISO 2022 JP or UTF 8 feature to set the char set at front end of the Application using the format QP or Base 64 to render encode and decode the Japanese text messages that sent via mail server 4 12 QAI The following are the test data for the above scenario picture 4 iso 2022 jp 5 118n Test Environment Setup To get in to setting up test environment we would just know about the resource bundle 5 1 What s Resource bundle hittp java sun com developer TechTips 1998 tt0521 htm A resource bundle contains locale specific objects for example strings representing messages to be displaye
3. culture specific information The hard coded strings of the software will be pulled out and stored in external files that are called as resource bundles and these will load at runtime 118n process typically involves the following tasks e Externalizing of strings graphics icons texts etc e Selecting code page and defining code page conversions e Modifying all the text manipulation functions to be aware of the code page e Changing the logic of all the formatting functions Date Time Currency Numeric etc e Changing the Collation sorting functions Note Code page is nothing but assigning a specific number to each character in a language in order to handle text It is a mapping table of characters to its numeric value ASCII is a good example of code page 2 2 Common Culture Specific Information e Externalization of strings No string should be hard wired to the code It should be externalized to a resource file so that it can be translated to the required language and can be applied during run time e Date and Time Formatting Month Day Year formats supported as to which comes first e Numeric and Currency formatting Currency symbols and how grouping the Numbers differ in each country e Collation Sorting Order Sorting order will change depending upon the native language Specific rules will be defined for sorting process based on the code page used 2 12 QAI 2 3 What is a Locale A locale consists of basic components such a
