Here’s a full test script in pyATS with local libraries that connects to a testbed of IOS devices, and runs various test cases that parses command outputs, collects router information, and report them in log.

This script requires one script argument testbed to be passed in when run
under standalone execution for demonstration purposes.
testbed: the path to testbed yaml file
This script requires one script argument testbed_file and two optional
script argument ios1 and ios2 to be passed in when run under easypy for
demonstration purposes.
testbed_file: the path to testbed yaml file
ios1: the device name defined in the testbed yaml file, if modified
ios2: the device name defined in the testbed yaml file, if modified

This script performs the following tests for demonstration purposes.
- router connection: basic device connection test
pingcommand: basic device ping test; logs ping result.- interface count verification
- execute
show versioncommand: basic command execution and data parsing; extract ethernet and serial interface counts; logs interface counts. - execute
show ip interface briefcommand: basic command execution and data parsing; extract all ethernet and serial interfaces; logs number of interface counts. - verify ethernet and serial interface counts from above commands.
- execute
- router disconnect: basic device disconnect test
