Abstract: An error reporting system is described that generates, for a user interface being output by a computing device, a report using one or more test scripts for the user interface locally at the computing device. In response to detecting input at an error reporting control included as part of the user interface, the error reporting system obtains test scripts designated for testing the user interface and generates test results by executing the test scripts at the computing device outputting the user interface. Screen displays output by the computing device are recorded during execution of the test scripts to capture a visual appearance of the user interface and are aggregated together with the test results and feedback from a user of the computing device to generate the report. The report is then transmitted to a service provider associated with the user interface.
