Comment (by mcalhoun@…):

 For reference:
 * The issue was first brought up on the [https://mail.kde.org/pipermail
 /kde-frameworks-devel/2015-November/thread.html#28556 KDE mailing list].
 * It then proceeded to the [http://lists.qt-
 project.org/pipermail/development/2015-November/thread.html#23735 QT
 mailing list].
 * A possible solution can be found in the
 [https://trac.macports.org/attachment/ticket/48967/qt5-kde.tar.bz2 zip
 file] of #48967 or the
 [https://github.com/RJVB/macstrop/blob/master/aqua/qt5-kde/files/fix-
 qstandardpaths3.patch git repository].

 If I understand the problem:
 * If {{{isTestModeEnabled()}}} returns true,
 [http://doc.qt.io/qt-5/qstandardpaths.html standard paths] change.
     * {{{/Library/Application Support}}} becomes {{{~/.qttest/Application
 Support}}}.
     * etc.
 * On OS X, {{{ApplicationsLocation}}} stays {{{/Applications}}} whether
 {{{isTestModeEnabled()}}} return true or not.[[BR]]
 * There is a program out there that runs
 {{{removeDir(ApplicationsLocation)}}} assuming that it is deleting a
 folder in {{{~/.qttest}}}
 * This assumption has catastrophic results on OS X.

 {{{isTestModeEnabled()}}} return true, what is {{{ApplicationsLocation}}}
 on Windows and Linux that would make {{{removeDir(ApplicationsLocation)}}}
 safe?[[BR]]
 Doesn't {{{removeDir(ApplicationsLocation)}}} delete '''ALL''' other
 application testing data and not just for that particular program?[[BR]]
 Are you simply not supposed to run two tests at the same time?

 This sounds like a problem that needs to be addressed either upstream or
 with the unit test writers.[[BR]]
 I would suggest submitting a bug or a patch with either group.
