[Qemu-devel] [PATCH v2 0/2] tests/acceptance: Add test of NeXTcube frame

Date: Mon, 1 Jul 2019 17:34:34 +0200

Hi,

I was looking at Thomas' last series [*] where he adds the
NeXTcube machine, thinking about enforcing a new rule "new
machines must have tests". Then I realized the UART is not
yet implemented, so our current sample tests are not helpful.

Since the framebuffer is working, I gave a try at dumping the
screen content via the HMP 'screendump' command, then parsing
the screenshot with an OCR tool.

The default ROM dump the bootlog to a console. Using the old
good tesseract tool we can recover some useful words to be
sure the guest is sane, its framebuffer is definitively working.

This test takes less than 6s on Travis-CI:
https://travis-ci.org/philmd/qemu/builds/552174983#L1836

   AVOCADO tests/acceptance
 (3/9) 
/home/travis/build/philmd/qemu/tests/acceptance/machine_m68k_nextcube.py:NextCubeMachine.test_bootrom_framebuffer:
  PASS (5.69 s)

Since v1: https://lists.gnu.org/archive/html/qemu-devel/2019-06/msg06514.html
- use the English dictionary (Thomas)
- support tesseract v3 and v4 (much better results with v4, but not
  all distros provide it)
- add a test of the framebuffer width/height

Regards,

Phil.
