Why is RQM always using the "None" channel instead of the first channel related to the test environment?

Hi guys,

First, I created 2 channels: one is called CH-Windows (linked to attribute OS > Windows), the other is called CH-Linux (linked to OS > Linux, respectively).

Then I created a keyword, which I linked to 3 different scripts: one script for each channel "None", "CH-Windows", and "CH-Linux". This keyword was then used in a test script, associated with a test case.

The latter test case was then added to a test plan. In this test plan, I created test environments for "OS > Windows" and "OS > Linux". Then I created executions records for the above test case: one TCER for OS > Windows, another for OS > Linux.

When I choose to execute either TCER (without options), I expected that RQM would expand the keyword according to the test environment associated with the TCER, i.e., in case TCER_Windows the system would use Windows specific script provided by the keyword:

"Note: If using channels, the Test Case Execution Record will run on the first channel to which its Test Environment is related. View a Test Environment in the Test Environment Editor to view its related channels." [Quoted from the RQM documentation: Running a test execution record]

But to my surprise, the keyword was always using the "None" channel script, although the test environment lists only a single channel. What struck me, was that each TCER  lists two channels: "None" and "CH-{Windows, Linux}".

But still, I'd expect that the system should be able to select the correct channel if it can be resolved; the "none" channel may serve as a fall-back, sure. But if the test environment is clearly providing a unique channel, why is the system no selecting this channel by itself?

Maybe my understanding of the matter is faulty. I don't know. I'd appreciate any insight you might share regarding this.

Thanks a lot & cheers,
Timo
