Khaled Hosny 9f544e5008 [test] Don’t skip subset tests early 
Check for FontTools only when the checksums are mismatching.

Khaled Hosny b084153317 [test] Remove subset tests from the slow suite 2021-08-04 04:12:31 +02:00
Khaled Hosny 7ccc52b075 [test] Compare sha256 hash before TTX dumps 
Most of time the files are identical, so instead of comparing the TTX
dump we can check sha256 hashes of the files first and if they match, we
don’t have to check the TTX dumps at all, making the subset tests orders
of magnitude faster.

time meson test --suite=subset down from:
real    0m19.418s
user    0m38.171s
sys     0m3.587s

to:
real	0m3.102s
user	0m8.622s
sys	0m1.701s

The expected files have been replaced by hb-subset output so they are
bit-identical where FontTools output might not.

The generate-expected-outputs.py now compares the hb-subset output with
fontttols subset and errors of they don’t match.

Khaled Hosny 10e73d188a [test] Add batch mode to hb-subset and use it 
time meson test --suite=subset down from:
real	0m22.822s
user	0m44.561s
sys	0m9.255s

to:
real	0m19.418s
user	0m38.171s
sys	0m3.587s

Does not seem to help much, but it is something.

Speed-up subset tests by saving TTX dump of expected output instead of

Khaled Hosny ddf87ffb22 [test] Add generated tests for emoji clusters 
Fixes https://github.com/harfbuzz/harfbuzz/issues/3017

Uses AdobeBlank2.ttf from:

  https://github.com/adobe-fonts/adobe-blank-2

instead of a dummy empty font so that everything maps to GID 1 and
control code points are kept instead of being dropped because there is
not space glyph (otherwise we’d need to identify control code points
somehow when generating the expectations).

Currently COLRv1 spec is being changed so the subsetting implementation is out of sync. Disable subsetting by failing sanitization for COLRv1 tables and disable all colrv1 tests.

Khaled Hosny c65e1e0842 [test] Run AOTS cmap tests with ot font functions only 
We are not interested in testing FreeType cmap support.

Fixes most format 4 tests. The remaining test seems to be peculiar, and
I can’t find any cmap implementation that produces the expected output.

Khaled Hosny 8396c523b6 [test] Add AOTS cmap tests 
Uses https://github.com/adobe-type-tools/aots/pull/3

Related to https://github.com/unicode-org/text-rendering-tests/issues/70

We don’t support format 4 or 8, so these tests are disabled. We support
format 4 but most of the tests are failing, investigating.

Khaled Hosny 50379fbb15 [util] Don’t split text at new lines in batch mode 
In batch mode (which is used for testing) we are probably not interested
in splitting text into lines as we could have split the string into
different tests. This fixes a bunch of AOTS tests that use newlines as
input.

Khaled Hosny 92b85749f2 [util] Strip quotes when parsing features 
When running in batch mode, the quotes are not stripped by the shell and
end up in the feature string. This breaks one of the AOTS tests.

Alternatively, we can remove the quotes from the test files, not sure
which is less hacky, though!
