Example Live DUT Testing

In order to connect to your remote devices, you will need to export the following environment variables:

export EOS_USER=your-login-name
export EOS_PASSWORD=your-login-password

If you are using an ssh-config file for hostname resolution (i.e. no DNS), you will also need to:

export EOS_SSH_CONFIG=<path-to-ssh-config file>

Snapshot Live DUT

In order to automatically create test-cases based on the existing operational states, you can use the nrfu-snapshot.py program. For exmaple:

./nrfu-snapshot.py switch-101.bld1

You can provide either the hostname (as shown) or the IP address of the device. Note that which every you use, you must ensure that the EOS device is configured to support eAPI.

Once you run this utility, you will see the following output indicating information about each of test functions. For example, running the command:

$ ./nrfu-snapshot.py switch-101.bld1

Will result in the following output

Ensure directory: switch-101.bld1
	[+] test-cabling creating 6 test-cases
	[+] test-lag-status creating 5 test-cases
	[+] test-interface-status creating 73 test-cases
	[+] test-optic-inventory creating 60 test-cases
	[+] test-mlag-status creating 1 test-cases
	[+] test-mlag-interface-status creating 4 test-cases

You should see the new directory switch-101.bld1, and inside there a number of JSON files storing the test-cases for each of the test functions, for example switch-101.bld1/test_optic_inventory.json

Run NRFU Tests

Once you have your test-cases created, you can then run the NRFU test utility:

For example using the same "switch-101.bld1" host:

./nrfu-dev.sh switch-101.bld1

The shell-script is a wrapper around calling pytest, and you should see as the first line in the output something like this:

+ pytest -v --tb=no --html=switch-101.bld1/report.html \
    --nrfu-device switch-101.bld1 \
    --nrfu-testcasedir switch-101.bld1

And then following that, the output of the pytest execution. The pytest run will generate an HTML report file that you can use to see details of each of the failed tests. You can open that report file in your browswer window directly
