How to prepare tests

In order to be sure that all components for a row in the test matrix are set up correctly, it makes sense to prepare as much as possible.
I create shortcuts for all combinations of QtC and NDK versions:

The shortcuts have a command line like this: <qtcbinary> -settingspath c:\temp\testmatrix_7.0_23.1 -noload UpdateInfo <testproject>
So, that each shortcut has its own settings directory. Then, each shortcut is executed once, and the default NDK and, a suitable default kit is selected.

Run tests

Have for example https://git.qt.io/playground/qtcreator-bug-snippets/-/tree/master/QTCREATORBUG-25030 checked out, and git clean -dxf the repository before each test matrix row.
Repeat the C++ debugging test at least twice per test row (without in-between cleaning of the repo).
Note for Qt Creator 7.0: Set QML debugging and profiling to Enabled in the Build Settings.
