Add a test that verifies the Tux logo is displayed on the framebuffer. We simply follow the OpenCV "Template Matching with Multiple Objects" tutorial, replacing Lionel Messi by Tux: https://docs.opencv.org/4.2.0/d4/dc6/tutorial_py_template_matching.html When OpenCV and NumPy are installed, this test can be run using: $ AVOCADO_ALLOW_UNTRUSTED_CODE=hmmm \ avocado --show=app,framebuffer run -t device:framebuffer \ tests/acceptance/machine_arm_integratorcp.py JOB ID : 8c46b0f8269242e87d738247883ea2a470df949e JOB LOG : avocado/job-results/job-2020-01-31T21.38-8c46b0f/job.log (1/1) tests/acceptance/machine_arm_integratorcp.py:IntegratorMachine.test_framebuffer_tux_logo: framebuffer: found Tux at position [x, y] = (0, 0) PASS (3.96 s) RESULTS : PASS 1 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0 | CANCEL 0 JOB TIME : 4.23 s Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Wainer dos Santos Moschetta <wainersm@redhat.com> Message-id: 20200225172501.29609-5-philmd@redhat.com Message-Id: <20200131211102.29612-3-f4bug@amsat.org> Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
