I have a unit test in which I am able to test sending DDS messages currently. However, I also want to implement the ability to test the message readers as well.
The problem is, due to the programs setup for creation of DDS readers and writers. If I try to make the readers I need, they already have the same topic as the writer and due to this an exception is thrown.
Has anyone thus figured out a way to simulate sending DDS messages to a reader as if they came from a DDS writer? Within one computer and no using separate computers on a network to do so.
You can use lookup_topicdescription() on the DomainParticipant to get a reference to the previously created Topic, if it exists. In pseudo-code, you could do something like
use lookup_topicdescription() to see if topic exists
if topic does not exist
use create_topic() to create the topic
If your application does this in multiple threads, then you will have to grab and release a lock around this code.
