Assignee: AMAZON TECHNOLOGIES, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A system, comprising:
at least one computing device; and
at least one application executable by the at least one computing device, wherein, when executed, the at least one application causes the at least one computing device to at least:
generate user interface content data for a user interface to be rendered on a client device;
identify a plurality of expected user interface feature identifiers based at least in part on the user interface content data, the plurality of expected user interface feature identifiers corresponding to a plurality of expected user interface features that are expected to be included in the user interface when rendered on the client device;
generate an expected feature digest based at least in part on a plurality of expected feature identifiers, the expected feature digest comprising a first array of bits corresponding to a reduced data size representation of a plurality of expected user interface features;
transmit the user interface content data to the client device;
receive a rendered feature digest from the client device, the rendered feature digest comprising a second array of bits corresponding to a reduced representation of a plurality of rendered user interface features that are included on the user interface that is rendered on the client device;
determine that at least one expected user interface feature is missing from the user interface rendered on the client device based at least in part on a comparison of the expected feature digest with the rendered feature digest; and
trigger a missing feature event in response to determining that the at least one expected user interface feature is missing from the user interface.
