Video-call user experience testing and assurance

A non-transitory computer-readable storage medium for use in conjunction with an electronic device, the computer-readable storage medium storing program instructions, wherein, when executed by the electronic device, the program instructions cause the electronic device to perform one or more operations comprising:

• receiving, associated with a second electronic device in a network, a request for testing;
• providing, addressed to a computer associated with a video-call service, a request for a video call based at least in part on the request for testing;
• receiving, associated with the computer, information specifying an address associated with the video call;
• providing, addressed to the second electronic device, an invitation for the video call, wherein the invitation comprises address information corresponding to the address;
• when the electronic device receives, associated with the computer, a notification that the video call has started, providing content addressed to the computer and intended for the second electronic device;
• obtaining communication-performance metrics associated with communication via the network during the video call and video-service performance metrics associated with the video call;
• and
• diagnosing a type of problem experienced at the second electronic device during the video call based at least in part on the communication-performance metrics, the video-service performance metrics and a pretrained machine-learning model.

A method for diagnosing a type of error, comprising:

• by an electronic device:
• receiving, associated with a second electronic device in a network, a request for testing;
• providing, addressed to a computer associated with a video-call service, a request for a video call based at least in part on the request for testing;
• receiving, associated with the computer, information specifying an address associated with the video call;
• providing, addressed to the second electronic device, an invitation for the video call, wherein the invitation comprises address information corresponding to the address;
• when the electronic device receives, associated with the computer, a notification that the video call has started, providing content addressed to the computer and intended for the second electronic device;
• obtaining communication-performance metrics associated with communication via the network during the video call and video-service performance metrics associated with the video call;
• and
• diagnosing a type of problem experienced at the second electronic device during the video call based at least in part on the communication-performance metrics, the video-service performance metrics and a pretrained machine-learning model.
