First, replace double quote characters with 3 escaped double quotes to allow QProcess::splitCommand() to treat it as an actual quote character that's part of the tag. Then, escape single quote characters so they don't interfere with the shell command and also to be treated as part of the argument. Lastly, surround the args with escaped double quote so that args with spaces are also treated as one. Amends b044323c1656aeeec508afab8457755cc1e8c587. Example of this: tst_qkeyevent::modifiers("M","e","t","a") for double quotes tst_qunicodetools::wordBreakClass(two words) for spaces tst_QSpinBox::stepSelectAll("don't select all") for single quotes Task-number: QTQAINFRA-5703 Change-Id: Ie4317e4350bbac619bac41e41f42613f50cf1ad4 Reviewed-by: Axel Spoerl <axel.spoerl@qt.io>
