An application may be tested under conditions associated with a computing device at a remote location by causing the computing device to perform various functions. However, if the computing device has entered into a locked or sleep mode, physical input such as the input of a password, number, or gesture may normally be required to terminate the locked or sleep mode. To enable inputs to be provided to the computing device from a remote location, the device may be paired with a communication device, such as a Bluetooth device, that is able to receive commands from a control device. Inputs from the communication device may be processed in the same manner as inputs from a human input device, such as a Bluetooth keyboard or mouse device, enabling the computing device to be transitioned from the locked or sleep mode without requiring physical input.

System for providing input to a remote device

A first device executing an application determines data indicative of conditions associated with the first device during use of the application. Based on correspondence between this data and threshold data that indicates conditions in which frames representing a display output of the first device should be stored, the first device is caused to send data indicative of these frames to a second device. The second device generates user interface data based in part on the received frames and may send the user interface data to other devices. To reduce the amount of data sent and the computational resources used, the first device may store only changed frames of display output, and may send data to the second device at times when a communication interface of the first device is active for other purposes.

Systems for controlling acquisition of test data from devices

When significant latency exists between a test device executing an application and a remote device used to debug the application, an intermediate device is used to receive requests from the remote device. When a first request is received, the intermediate device determines other requests that are related to the first request, sequentially sends the other requests to the test device, and receives a response after each request, using a wired connection or a wireless network having lower latency than wireless communication between the remote device and the test device. The intermediate device then sends each of the responses to the remote device. The remote device stores the responses. The remote device is then able to use the stored data to determine responses for subsequent requests.

Systems for exchanging data using intermediate devices

The power consumption associated with use of an application is determined by causing one or more devices to execute the application. The state of the power source for each device is determined before, during, and after execution of the application. The state may include an amount of power discharged by the power source, an amount of power used to maintain a charge level of the power source, or a difference between a baseline power use and the amount of power consumed during use of the application. The determined states for the power sources of each device are used to generate an output that indicates periods of high and low power use. The output may associate these periods of power use with different characteristics of the functions that were performed during those time periods or of the devices. Using the output, a developer may optimize power use associated with an application.

System for determining power consumption by devices

Mobile devices executing applications may be tested for networking issues by utilizing a test network having proxy access devices placed at different physical locations. Devices may be stored in a secure enclosure that includes a host device. The enclosure includes access controls to prevent unauthorized removal of devices or access to stored data. If an unauthorized access, disconnection from the host device, or disconnection of a device from a power source is detected, devices may be placed into a locked state or data on the devices may be deleted. The enclosure may also include a control device for testing the exchange of Bluetooth data by the devices. The enclosure may also include conductive members placed on the touch sensors of devices for providing simulated touch input to the touch sensors by changing the capacitance of adjacent regions of the touch sensors.

Secure enclosure for devices used to test remote connectivity

Application debug protocols that require waiting for responses between each request may be adversely affected if significant latency exists between a test device executing an application and a remote device used to debug the application. To address this, the test device is connected to a separate device that receives requests from the remote device. When a first request is received, the separate device determines other requests that are related to the first request, sequentially sends the other requests to the test device, and receives a response after each request, using a wired connection affected by less latency than communication with the remote device. The separate device then sends each of the requests and responses to the remote device for storage. When the remote device prepares to send a subsequent request, if a response can be determined using the stored data, the stored data is used to determine the response locally.

Systems for exchange of data between remote devices

Devices at different geolocations are configured to determine and share information regarding execution of an application under various conditions. Data determined by a user device includes private information, such as screen capture data, location data, or information about the user. The user device processes the data locally, such as by determining performance metrics or other characteristics of execution of the application, and sends this information to a server. The data sent to the server excludes the private information. The server determines additional data associated with execution of the application by devices other than the user device, which may include screen capture data or location data associated with those other devices. The additional data is used in conjunction with the data received from the user device to generate interfaces indicative of performance metrics of the application.

Systems for remote determination of data from test devices

Mobile devices executing applications utilize data services worldwide, with issues involving the transfer of data on the network impacting the operation and user experience of those applications. Network data is acquired from a mobile computing device during communication and processed to determine occurrence of a burst which is representative of elements in the network data that are determined to be causally related. Bursts are analyzed, and those associated with poor performance are presented in a user interface. The user interface provides impact information about the effect the burst had on operation of the application. The user interface may provide suggestions to mitigate the poor performance. If no problem is determined by the system, but the user believes a problem to have occurred, user input is collected and used to trigger a workflow to analyze the burst. Subsequent results of this analysis are returned to the user via the user interface.

System for assisting in assessment and mitigation of data network operations

Devices at different geolocations are configured to determine and share information regarding execution of an application under various conditions. A device executing the application, or another device connected to the device executing the application, may send data determined by executing the application to a central device. The central device may in turn receive requests from other devices and provide the determined data to the other devices. The devices may be configured to exchange data using native debugging or bridge software on the devices by determining communication parameters that are common to each device, such as protocols, networks, intermediate devices through which communications may be passed, and so forth. To reduce the amount of data that is transmitted portions of the data related to communications between devices, such as acknowledgement codes, may be identified and withheld from sending.

Systems for remote communication with test devices

A machine learning system is trained to determine scores indicative of a quality of video data based on the characteristics of the video data, without requiring information regarding the correct appearance or other aspects of the video content. To train the machine learning system, users input scores for videos having predetermined quality scores, videos that have been previously seen by the users, and videos that have not been previously seen by the users. The differences between a user's score and a predetermined score or a score previously input by the user are used to determine a consistency metric. The scores and consistency metrics determined for a group of users, and the video characteristics of the videos presented to the users, are used to train the machine learning system to determine scores indicative of the quality of a video based on the characteristics of the video.

Reference-free system for determining quality of video data

Mobile devices worldwide execute applications that utilize data services, with issues involving the transfer of data via networks impacting the operation and user experience of those applications. Data is acquired from a mobile computing device executing an application and processed to determine occurrence of a group of related activities performed when executing the application. Parameters of the activities are analyzed, and those parameters associated with poor performance are presented in a user interface. The interface provides impact information about the effect of the activities on operation of the application and may include recommended actions to mitigate the poor performance. A user may interact with data within the interface to trigger a workflow to analyze indicated portions of the data. Subsequent results of this analysis may be returned to the user via the user interface or may be implemented as analytic rules for subsequent data processing.

System for identifying issues during testing of applications

A test device may include a performance module to determine entropy values for images, such as of a graphical user interface, to be presented on a display device of the test device. An entropy value for an image may be indicative of a distribution of data values, such as intensity or color values for pixels in the image. Patterns of entropy values over time may provide information indicative of performance of the test device. For example, a constant entropy value over time may indicate the graphical user interface is not changing. In another example, particular patterns of entry values over time may be indicative of presentation of wait indicators or other user interface elements. The entropy values may be used to determine data indicative of performance of the test device. This data may be stored locally, sent to an external device, and so forth.

System to determine performance based on entropy values

The power consumption associated with execution of an application is determined by causing one or more devices to execute the application. At multiple times before, during, and after execution of the application, the state of the power source for each device is determined. The state may include an amount of power discharged by the power source, an amount of power used to maintain a charge level of the power source, or a difference between a baseline power use and the amount of power used during execution of the application. The states for the power sources of each device are used to generate an output that indicates periods of high and low power use, and shows these periods of power use in association with different characteristics of the functions that were performed during those time periods. Using the output, a developer may optimize power use associated with an application.

System for determining power consumption by a test device

Mobile devices executing applications utilize data services worldwide. Testing of the applications for networking issues is facilitated by utilizing a test network having proxy devices placed at different physical locations. A tester may use the test network to direct traffic to and from an application under test to one of the proxy devices. Using the proxy device, the traffic is then exchanged with a real-world network, such as a cellular data network, at the different locations. The tester may thus test operation of the application under test in real-world conditions at a variety of different physical locations. The system may include a proxy host device with an intermediate module to establish Virtual Private Network (VPN) connections and to capture VPN data, including VPN protocol data, session data, and other data. The VPN data may be provided to a network system to analyze performance of an application under test.
