We hope this shall avoid some flaky failures noticed in quick tests,
e.g. tst_QQuickMenu::Material::subMenuPosition(cascading,flip) was
recently seen failing with 3.88e-11 != 0. This required some revision
to test data in the testlib selftest for floats; the resulting
expected output differs in details but not in which tests pass or
fail. QEMU, naturally, made life difficult, requiring special-case
code in the test-driver.
[ChangeLog][QtTestLib][QCOMPARE] QCOMPARE() now treats its values as
equal when qFuzzyIsNull() is true for both of them.

In QCOMPARE, handle NaNs and infinities the way tests want them
handled, rather than by strict IEEE rules. In particular, if a test
expects NaN, this lets it treat that just like any other expected
value, despite NaN != NaN as float16 values. Likewise, format
infinities and NaNs specially in toString() so that they're reported
consistently.
Enable the qfloat16 tests that depend on this QCOMPARE() behavior.
Refise the testlib selftest's float test to test qfloat16 the same way
it tests float and double (and format the test the same way).
This is a follow-up to 37f617c405.

The QTest::qCompare() implementations were almost duplicates; pull the
common code out into a templated version. Tweaked the
QTest::toString() specialization for float and double (a macro) and
fixed a bous modifier in double's format.
The doubleComparisons and floatComparisons tests in the tst_float.cpp
selftest shared a large block of tests in common, aside from the
difference of type. Break this out into a templated static function
to save duplication.
This prepares the way for using the same templated code for qfloat16.

Tidied up the existing float tests in the process.
(In particular, s/SUCCESS/PASS/ since that matches real test output.)
These verify that QCOMPARE() handles floats and doubles as intended.
Extended the existing qFuzzyCompare tests to probe the boundaries of
the ranges of values of both types, in the process.
Revised the toString<double> that qCompare() uses to give enough
precision to actually show some of the differences being tested there
(12 digits, to match what qFuzzyCompare tests, so as to show different
values rather than, e.g. 1e12 for both expected and actual) and to
give consistent results for infinities and NaN (MinGW had eccentric
versions for these, leading to different output from tests, which thus
failed); did the latter also for toString<float> and fixed stray zeros
in MinGW's exponents (which made a kludge in tst_selftest.cpp
redundant, so I removed that, too).
That's further complicated handling of floating-point types, so let's
just keep an eye on how expensive that's getting by adding a benchmark
test for QTest::toString(). Unfortunately, default settings only get
runs that take modest numbers of milliseconds (some as low as 40)
while increasing this with -minumumvalue 100 or more gets the process
killed - and I'm unable to find out who's doing the killing (it's not
QProcess::kill, ::kill or the QtTest WatchDog, as far as I can tell).
So results are rather noisy; the integral tests exhibit speed-ups by
factors up to 5, and slow-downs by factors up to 100, between runs
with and without this change, which does not affec the integral tests.
The relatively modest slow-downs and speed-ups in the floating point
tests thus seem likely to be happenstance rather than signal.

In selftests.qrc, imposed alphabetic order (on stem of name, then on
suffix, effectively treating . as sorting before any letter) while
removing old tests and adding new tests and data. Updated all non-csv
files and added many missing files. (Not clear on csv support status;
the script seems to have dropped it after 5.6, but the test still uses
it.)
Left expected_crashes* alone (no new files added, no update to old) as
I don't get results resembling those anticipated.
Omitted printdatatagswithglobaltags, printdatatags due to dangling

We need to have a finer grained control over the tests
we skip in our CI system. This adds a blacklisting
mechanism that allows blacklisting individual test
functions (or even test data) using a set of predefined
matching keys for the operating system and some other
relevant variables.
QTestlib will search for a file called BLACKLIST in the test
directory and parse it if found. The file contains a simple
ini style list of functions to blacklist. For details see
qtestblacklist.cpp.

Make the various versions of the failure message align consistently so

consistent across all versions of the message.

For data-driven tests, testlib previously counted one fail or skip for
each data row that failed or skipped, while it counted only one pass
for a test function where all rows passed and counted no passes for a
test function where some rows passed and some rows failed. A similar
problem also existed for benchmark tests, which could run multiple
iterations of the same test, with each fail and skip being counted but
only a single pass being counted for the entire series of iterations.
This commit makes testlib count one pass, fail or skip for each data
row. Test functions that are not data-driven count one result for the
test function, as before. Benchmark tests count one pass, fail or skip
per iteration.
A side-effect of this change is that the test output in plain text, xml
and light xml formats now shows a result for every data row and
benchmark iteration executed, allowing post-processors to correctly
calculate the total number of tests executed. Previously, individual
rows were not shown in the test output if they passed, making such
calculations impossible.
The only change to the xunitxml output format is to correct a bug where
no test result was recorded for a test function if the last data row
was skipped and all other rows passed -- in which case the overall
result should be a pass. Note that there is also a pre-existing bug
in the xunit logger, where no result is reported if all rows are
skipped; that bug is unaffected by this commit.

Correct a bug in the test and use unique names for data rows. The bug
was that the test assumed that QCOMPARE for float values 100001 and
100002 would fail, but it actually succeeds. QCOMPARE for floats uses
qFuzzyCompare(), which succeeds if the numbers differ by no more than
1/100,000th of the smaller value. Thus QCOMPARE(100001, 100002) passes,
while QCOMPARE(99998, 99999) fails.
