pytest: Show a message when sandbox crashes
When a test hands on a real board there is no way on the console to obtain
any information about why it hung.
With sandbox we can actually find out that it died and get a signal or
exit code. Add this to make it easier to figure out what happened.
So instead of:
test/py/u_boot_spawn.py:171: in expect
c = os.read(self.fd, 1024).decode(errors='replace')
E OSError: [Errno 5] Input/output error
We get:
test/py/u_boot_spawn.py:171: in expect
c = os.read(self.fd, 1024).decode(errors='replace')
E ValueError: U-Boot exited with signal 11 (Signals.SIGSEGV)
