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 The framework will use the user's SSH key to authenticate. User password can be specified, in which case it will be used, but it's strongly discouraged. There are configuration files with a README that help with setting up the execution/development environment. The code only connects to a node. You'll see logs emitted to console saying where DTS connected. There's only a bit of documentation, as there's not much to document. 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. 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. 3. Once we have 2 applied, we're 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. There's some work already done on Traffic generators we'll be sending as a dependence on this patch series. 4. After 3, we'll add a basic performance testcase which doesn't use Scapy, but Trex or Ixia instead. 5. 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. We're already working on items 2-4 and we may send more patches even before this patch series is accepted if that's beneficial. The new patches would then depend on this patch. This patch, as well as all others in the pipeline, are the result of extensive DTS workgroup review which happens internally. If you'd like us to make it more public we'd have no problem with that. v3: Added project config files and developer tools. Removed locks for parallel nodes, which are not needed now and will be implemented much later (in a different patch). v4: Minor fixes - added missing Exception and utils function. v5: Reordered commits because the dependencies between commits changed. Added more developer tools. Added definitions of DTS testbed elements. Reworked SSH implementation - split it so that the split between an abstraction and the actual implementation is clearer. Modified the directory structure to better organize the current and the future code. v6: Minor code/grammar/style changes and a minor bugfix suggested by Stanislaw.
