ros2cli network tests

[tfoote]

Test the basic functionality of the ros2cli package family in an environment where nodes are running on other machines on the network.

Setup

• Rmw: Connext
• BuildType: Binary
• Chip: Amd64
• Os: Windows

Links

• Repo URL

Checks

• Node discovery

  With another node running, use ros2 node list to ensure that the expected node is listed. Then stop the node and ensure that the list operation no longer shows the node.

• Topic discovery

  With another node running, use ros2 topic list to ensure that the expected topics are listed. Then stop the node and ensure that the list operation no longer shows the node's topics.

• Service discovery

  With another node running, use ros2 service list to ensure that the expected services are listed. Then stop the node and ensure that the list operation no longer shows the node's services.

• Parameter discovery

  With another node running, use ros2 param list to ensure that the expected parameters are listed. Then stop the node and ensure that the list operation no longer shows the node's parameters.

I did the ros2 binary install on Windows 10 with rmw_connextdds as the RMW implementation with RTI 7.5.0. The ros2cli commands work when no other nodes are running.

talker, listener and simple launch commands fail with rmw_connextdds so I could not test the above commands when another node is running. Therefore, the above tests pass but only partially.

Tried with RTI 7.3.0, it works.
