How would an e2e test catch this though? What would the test condition be? Wouldn’t I have to be checking for audio from the other party during all seemingly random events like adding a person to the call group?
Apologies in advance for my ignorance, I haven’t written code for a long time.
I doubt there would be a specific test (or maybe there would, real testers are better than me at thinking of this stuff), but there should be logs for events like "microphone turned on" and "user joined group chat" and the testers should be monitoring those logs.
Not sending any audio or video until a call gets accepted seems like a clearcut test case. They probably have a few tests like that, too, but forgot to add weird edge cases.
