History

Giuseppe D'Angelo 5560723e9d QCOMPARE: restore compatibility with braced-init-lists `a611a9f537` (in Qt 5) added support for mixed-type comparisons through QCOMPARE. That commit added a new overload for qCompare taking two types, T1 and T2; but it also left the same-type qCompare(T, T) overload around, guarded by a Qt 6 version check. The mixed-type version is however not a generalization of the same-type one, because it won't work if one of the arguments doesn't participate in FTAD. Case in point: braced-init-lists. In Qt 5 this worked: QCOMPARE(some_container, {42}); but in Qt 6 it does not work any more. The mixed-type overload fails deduction (can't deduce T2); in Qt 5 the same-type overload deduced T=SomeContainer, and {42} was used to select a constructor for SomeContainer. -- There's a partial, straightforward workaround for this: default T2 to T1 in the mized-type overload. In that case T2 has a "fallback" if it cannot be deduced. This is partial because of course doesn't address the case in which T1 cannot be deduced, but I don't think that is common at all. QList is special here, because it has qCompare overloads that makes it comparable with arrays, initializer lists and more. I don't like that very much -- we should probably have a qCompare(input_range, input_range) overload, but that's an exercise for C++20.

README

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.

Linux X11:

   * The user must be logged in to an active desktop; you can't run the
     autotests without a valid DISPLAY that allows X11 connections.

   * The tests are run against a KDE3 or KDE4 desktop.

   * Window manager uses "click to focus", and not "focus follows mouse". Many
     tests move the mouse cursor around and expect this to not affect focus
     and activation.

   * Disable "click to activate", i.e., when a window is opened, the window
     manager should automatically activate it (give it input focus) and not
     wait for the user to click the window.
