[Qemu-devel] [PATCH v3 1/3] tests/acceptance: Add test of NeXTcube framebuffer using OCR |
Date: |
Tue, 13 Aug 2019 15:49:19 +0200 |
From: Philippe Mathieu-Daudé <address@hidden>
Add a test of the NeXTcube framebuffer using the Tesseract OCR
engine on a screenshot of the framebuffer device.
The test is very quick:
$ avocado --show=app,console run tests/acceptance/machine_m68k_nextcube.py

v2:
- test fb sizes
- handle 2 versions of teseract
v3:
- sort imports
- use of ALL_CAPS variables if they are at the module level (PIL_AVAILABLE)
- use find_command from avocado.utils.path
- check tesseract version using regex to avoid exceptions
- do not use '-' in avocado tags
- use use os.path.join()
- add few comments
