Shell Test

This example shows testing of a device's shell using BLEShellService. It sends a simple ping command that is expected to be implemented by the target device.

It consists of two files:

conftest.py - Implements a fixture that connects to the first device with EmbedOps in the name.

test_shell.py - Contains a test that executes a single shell command.

This test also makes use of the pytest-asyncio module, which adds asyncio capabilities to PyTest.
