Use a script, which can be tested independently of CI code (by running
it on the host on which it will be used), and print the directory that
has been prepared in the HTML. Also, in the description, use the
infinitive/imperative(?) of the verb to harmonize with other steps.
- no need to specify "single-ue" profile when running iperf test for 1 UE only
- default profile "balanced" can be used instead, computes BW for 1 UE correctly
Ensure that the UE has an IP address before continuing the test.
Otherwise, it might happen we ping before the UE is connected.
Do not do this in do-ra and phytest, as they use --noS1, which implies
statically assigned IP address, so IP address check always succeeds(!).
Make RFsim start up faster by starting core and RAN start at the same
time. This speeds up because we do not wait for "healthy" containers
serially, but parallely.
For the RAN, it is safe to start gNB and UE at the same time in SA mode
(as the UE will only attach once the radio, and hence the full gNB, is
ready).
We do not start in parallel in do-ra and phytest, as in these modes the
gNB first has to write a UE-specific configuration file. If we start
both gNB and UE at the same time, the UE might try to read the file
before it is written, leading to a failure.
