Many surveys are not only using one languages, but offer the respondent to choose the survey language at the beginning.
SurveyTester supports multiple languages for a while, but now we added a way for connecting the language question inside the survey with the language definition in SurveyTester.
Once, Surveytester has initially "seen" this question, SurveyTester offers to qassign the question categories to the already added languages. When fully automated testing is in place, SurveyTester is using these information for answering your survey the right way.
