All the necessary code needed to connect to a node in a topology with
some extras, such as basic logging, per-node locks and some extra
useful methods.
To run the code, modify the config file, conf.yaml and execute ./main.py
from the root dts folder. Here's an example config:
executions:
- system_under_test: "SUT 1"
nodes:
- name: "SUT 1"
hostname: 127.0.0.1
user: root
password: mypw
The code only connects to a node. You'll see logs emitted to console
saying where DTS connected.
There's no documentation, as there's not much to document - the above is
basically all there is to it, as far as user docs go. We'll add some
real docs when there's enough functionality to document, when the
HelloWorld testcases is in (point 4 in our roadmap below). What will be
documented later is runtime dependencies and how to set up the DTS
control node environment.
This is our current roadmap:
1. Review this patchset and do the rest of the items in parallel, if
possible.
2. Rework the parallel lock mechanism using something simpler using
existing Python tools.
3. Add tools which aid with DTS control node environment setup and
document their usage.
4. We have extracted the code needed to run the most basic testcase,
HelloWorld, which runs the DPDK Hello World application. We'll split
this along logical/functional boundaries and send after 1 is done. In
fact, 1 is part of 4.
5. Once we have 4 applied, we'll planning on adding a basic functional
testcase - pf_smoke. This send a bit of traffic, so the big addition is
the software traffic generator, Scapy.
6. After 5, we'll add a basic performance testcase which doesn't use
Scapy, but Trex or Ixia instead.
7. This is far in the future, but at this point we should have all of
the core functionality in place. What then remains is adding the rest of
the testcases.
v2:
Reworked config parser.
Extended logging to log to files as well.
Added type annotations to most of the code.
