Amends commit 0756cc1eae.
The generic instantiation of this function had a std::nullptr_t *
parameter, but callers had special code to pass a nullptr there because
we never needed a value of a nullptr (it's always a null pointer). For
example, in compare_ptr_helper():
auto lhsFormatter = Internal::pointerToString<QObject>;
auto rhsFormatter = Internal::genericToString<std::nullptr_t>;
return compare_helper(t1 == nullptr, "Compared QObject pointers are not the same",
const_cast<const QObject *>(t1), nullptr,
lhsFormatter, rhsFormatter, actual, expected, file, line);
But in debug mode, some compilers did emit a load from this memory
location, causing a crash. So we just specialize this function to avoid
such.
We had a test for this... except it was never reached because the
earlier QCOMPARE() had already failed. For the test, this amends
commit ae02188233.
Conflict resolution for 6.8: regenerated the expected output for
tst_selftest.

QPalette specifically has quite a large amount of output (1363
characters) when toString
is called on it. We should make sure that we can fit that in our
failure messages. This patch does that by increasing the limit from
1024 characters to 4096.

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.

The regex used a greedy .+ to match an actual dot and a space,
preceding an open parenthesis, with the result that if the message
contained any parentheses that .+ swallowed everything up to the last
of them. Correct the regex so that recently-added tests' error
messages show up correctly.

The recently added test for QTestEventLoop produced a message which
the TAP test-logger mis-parses. Since that message shall soon go away
(when I fix the bug the new test exists to verify), modify one of
cmptest's QVERIFY2() messages to trip up the same bug, so we can spot
any regressions on this in future (after the imminent fix to this TAP
issue).

For built-in types, this is a compile-time assert - we should not have
any types in Qt for which we have neither debug streaming nor a
QTest::toString specialization implemented. A build of most of Qt
submodules passes with this change, after minor modifications to some
tests. We cannot declare QSizeHint::Policy as a metatype after the
QMetaType has already been instantiated for it, and the QDebug stream
operator for QElaspedTimer needs to be correctly declared within the
namespace.
Add a self-test function for a custom type, and update reference files
of the self-test.

Before 0681a2dd5a, QCOMPARE'ing types
for which no QTest::toString specialization exists did not output
Actual and Expected lines on failure, as that would only print <null>
for both values (which then look like the same value, confusingly).
Commit 0681a2dd5a changed that behavior,
and started printing the confusing <null> values.
Take care of the logic in the formatFailMessage function: if both values
are nullptr, then print only the variable names, but not the confusing
<null> text representation of the values.
Remove dead and duplicated code related to the formatting logic, add a
self-test function, and update the expected_cmptest files.

It is unnecessary to create a QList container just for comparison.
Split out helpers for comparing sequence sizes and sequences from
qCompare(QList) and add a template for an array with a non-type template
parameter for the size.
One can then write something like:
const int expected[] = {10, 12,...};
QCOMPARE(QFontDatabase.pointSizes(...), expected)
Unfortunately, any commas in such an array will be misread by macro expansion
as macro argument separators, so any expected array with more than one entry
needs an extra macro expanding __VA_ARGS__.

The Test Anything Protocol (TAP), was originally Perl's simple text-based
interface between testing modules and test harnesses, but has since been
adopted by a large number of producers and consumers in many different
languages, which allows colorizing and summarizing test results.
The format is very simple:
TAP version 13
ok 1 - test description
not ok 2 - test description
---
message: 'Failure message'
severity: fail
expected: 123
actual: 456
...
ok 3 - test description # SKIP
1..3
The specification [1] is very brief, so the implementation has been
based on how typical consumers behave, especially when it comes to
the undefined diagnostics block.
