Prior to this commit, display names were "sanitized" before they were printed via the ConsoleLauncher (junit-team#1713), and text-based arguments in display names for parameterized tests were quoted and escaped (junit-team#4716). However, there was still the chance that display names could contain control characters such as CR or LF. To address that, this commit introduces support for automatically replacing non-printable characters in any display name passed to one of the constructors for AbstractTestDescriptor. Doing so automatically covers all display names in JUnit Jupiter, @SuiteDisplayName, and any other test engines that subclass AbstractTestDescriptor, which should cover most common use cases. Specifically, the following replacements are performed. - \r -> <CR> - \n -> <LF> - ISO control character -> � (Unicode replacement character) This commit also removes the special handling of ISO control characters from QuoteUtils, since this is now handled in AbstractTestDescriptor. See junit-team#1713 See junit-team#4716 Closes junit-team#4714

@sormuras, I already used Japanese text in the test, but I just added (and force pushed) Thai text in the test. And I had already used an emoji. So I think we are adequately testing support for multi-byte characters. |
