Hi All,
I have shared a Test TANGO device code which replicates the error described in the previous post.
When Test device is running (Test.py file), get_name() API is executed properly.
user@theta:~/TEST/Test$ python Test.py 01
('self.get_name() is: ', 'test/device/1')
Ready to accept request
However, when pytest (Test_test file) command is executed, it gives following error:
user@theta:~/TEST/test$ pytest

Any inputs on this will be helpful.
