A Utility for Showing Program Integrated Information Changes between Versions in a Translation Verification Test

We invented an efficient approach for Translation Verification Test (TVT). This approach allows testers to recognize changes in the Program Integrated Information (PII) strings from an old version to a new version. This approach not only shows the changes, but also displays the original English strings next to the Japanese strings. We can apply this approach to most internationalized software. Testers can avoid unnecessary checking of the PII strings that were checked in the prior TVTs. By using this approach, the time for checking the PII strings can be reduced by up to 5% of the usual time. The simultaneous display of the Japanese and English PII strings also helps the testers to improve the quality of the verification.
