Hi Team,

I am working of testing temporal signal in integration test. PFB required details-

Background-

Dev Code-

workflow A - Orchestrator workflow
Workflow B and C two other workflow govern by A
Workflow A started one task and pass to workflow B to do required job.
while working on task, workflow B identified one emergency case and send notification using signal to pause workflow A till the time A acknoledge the signal

based on private attribute isEmergency, if it is true
{
B send signal to A
To send signal from B to A → B stbubbed A using untypedExternalStub method.
}

Approach Tried-

  1. using testEnvironent
  2. Started A with untyped stubbed and then B sothat A can acknoledge the signal and B continue task

Both the cases, it is keep on waiting for signal to be acknoledge and as per log I can see B are trying to send signal multiple time in endless loop or till the time timeout occur

Question-
Could you please suggest working example to test signal in integration test mentioned above. where signal method does not have any input/output parameter

Regards,
