Pekka Paalanen	97359ba5c5	tests: add output transform tests This goes through all output transforms with two different buffer transforms and verifies the visual output against reference images. This commit introduces a new test input image 'basic-test-card.png'. It is a small image with deliberately odd and indivisible dimensions to provoke bad assumptions about image sizes. It contains red, green and blue areas which are actually text that makes it very obvious if you have e.g. color channels swapped. It has a white thick circle to highlight aspect ratio issues, and an orange cross to show a mixed color. The white border is for contrast and a 1px wide detail. The whole design makes it clear if the image happens to be rotated or flipped in any way. The image has one pixel wide transparent border so that bilinear sampling filter near the edges of the image would produce the same colors with both Pixman- and GL-renderers which handle the out-of-image samples fundamentally differently: Pixman assumes (0, 0, 0, 0) samples outside of the image, while GL-renderer clamps sample coordinates to the edge essentially repeating the edge pixels. It would have been "easy" to create a full matrix of every output scale & transform x every buffer scale & transform, but that would have resulted in 2 renderers * 8 output transforms * 3 output scales * 8 buffer transforms * 3 buffer scales = 1152 test cases that would have all ran strictly serially because our test harness has no parallelism inside one test program. That would have been slow to run, and need a lot more reference images too. Instead, I chose to iterate separately through all output scales & transforms (this patch) and all buffer scales & transforms (next patch). This limits the number of test cases in this patch to 56, and allows the two test programs to run in parallel. I did not even pick all possible scale & transform combinations here, but just what I think is a representative sub-set to hopefully exercise all the code paths. https://gitlab.freedesktop.org/wayland/weston/issues/52 Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>	5 years ago

tests: introduce struct fixture_metadata

This allows tests to give a meaningful name for their fixture setups
when they use more than one of them.

If a test uses DECLARE_FIXTURE_SETUP_WITH_ARG(), it must now pass a
third argument naming the field which is struct fixture_metadata. This
also means that the fixture setup data must now be a struct, it cannot
be a plain type anymore. A compiler error is generated if the field type
is not the expected one.

All tests using DECLARE_FIXTURE_SETUP_WITH_ARG() and converted to the
new form and given names for their fixture setups.

The fixture setup names not actually used yet, that will be another
patch.

tests: add output transform tests

This goes through all output transforms with two different buffer transforms
and verifies the visual output against reference images.

This commit introduces a new test input image 'basic-test-card.png'. It is a
small image with deliberately odd and indivisible dimensions to provoke bad
assumptions about image sizes. It contains red, green and blue areas which are
actually text that makes it very obvious if you have e.g. color channels
swapped. It has a white thick circle to highlight aspect ratio issues, and an
orange cross to show a mixed color. The white border is for contrast and a 1px
wide detail. The whole design makes it clear if the image happens to be rotated
or flipped in any way.

The image has one pixel wide transparent border so that bilinear sampling
filter near the edges of the image would produce the same colors with both
Pixman- and GL-renderers which handle the out-of-image samples fundamentally
differently: Pixman assumes (0, 0, 0, 0) samples outside of the image, while
GL-renderer clamps sample coordinates to the edge essentially repeating the
edge pixels.

It would have been "easy" to create a full matrix of
every output scale & transform x every buffer scale & transform, but that
would have resulted in 2 renderers * 8 output transforms * 3 output scales *
8 buffer transforms * 3 buffer scales = 1152 test cases that would have all
ran strictly serially because our test harness has no parallelism inside one
test program. That would have been slow to run, and need a lot more reference
images too.

Instead, I chose to iterate separately through all output scales & transforms
(this patch) and all buffer scales & transforms (next patch). This limits the
number of test cases in this patch to 56, and allows the two test programs to
run in parallel.

I did not even pick all possible scale & transform combinations here, but just
what I think is a representative sub-set to hopefully exercise all the code
paths.
