Abstract

The invention relates to a device and a method for automatically processing functional tests of applications built into a point of sale (POS), enabling the sales transactions carried out in the POS' to be of high operating quality. A primary aim of this invention is thus to provide a device for automatically processing functional tests of applications built into a POS, which comprises an automation and processing appliance that connects to a POS by means of a plurality of linkages, replacing all of the means that were originally connected to the POS in the normal arrangement thereof, the POS maintaining a connection to a Local Area Network (LAN) and to a shop controller. In the automation and processing appliance, the POS connects directly, by means of the linkages, to a processing unit contained by the automation and processing appliance, where one of the linkages, in turn, optionally connects to at least one fiscal card that, in turn, connects to a processing unit. The processing unit also connects to an automation unit, also contained by the automation and processing appliance, and to the personal computer (PC). Furthermore, the automation unit contains a PinPad interface and a PinPad. The automation unit is used to emulate the action of the user, swipe a magnetic card, and press the keyboard for a transaction, and in addition, the processing unit is connected to fiscal cards, which are optional in some cases, but cannot be acted upon or modified, as is also the case with the PinPad. In this way, the processing unit can emulate the operation of all of the peripheries connected to the POS, except the fiscal control cards and the PinPad. The PinPad interface emulates the action of a user by means of a magnetic head interface that supplies a signal to the magnetic head of the PinPad, which is the equivalent to swiping a magnetic card, and an activator of the PinPad keyboard acts on the keyboard, marking the keys of the keyboard of the PinPad, simulating a user transaction.

La unidad de procesamiento (120) puede emular el funcionamiento de todos los periféricos conectados al POS (20), salvo las tarjetas de control fiscal (82,83) y el PinPad (94). The invention proposed basically in Figure 2, allows all the connections that the POS (20) with its peripherals have, are replaced by a connection with the automation and processing apparatus (80) through the links (45,46, 47,48,49), automation and processing apparatus (80) which is also connected to a PC (70) that executes the control work of said automation and processing apparatus (80) on the POS (20), which maintains the connection to the store controller (60) through the LAN (40). Figure 3 shows the scheme of the automation and processing apparatus (80), connected to the POS (20) and the PC (70). The automation and processing apparatus (80) is composed of a processing unit (120) and an automation unit (90) containing a PinPad interface (92) and a PinPad (94); the automation unit (90) allows to emulate the action of a user, pass a magnetic card and press the keyboard for a transaction, in addition, the processing unit (120) is connected to a pair of tax cards (82,83), which in some cases are optional, but cannot be intervened or modified, as is the case with the PinPad (94). The processing unit (120) can emulate the operation of all peripherals connected to the POS (20), except for the fiscal control cards (82.83) and the PinPad (94).
En la figura 4 se muestra un diagrama en bloques detallado del aparato de automatización y procesamiento (80), la unidad de procesamiento (120) puede controlar que tarjeta fiscal (82,83) se conmuta para las prueba, mediante el enlace (141) que actúa sobre dicho conmutador (84); una interfaz (140) adapta las señales eléctricas que recibe/transmite un microcontrolador (130) con la tarjeta fiscal (82,83) elegida, en base a un programa de aplicación que ejecuta este microcontrolador (130). El microcontrolador (130) interactúa con el PinPad (94) a través de la segunda interfaz RS232 (131), en donde la interfaz PinPad (92), emula la acción de un usuario, mediante una interfaz cabezal magnético que entrega una señal al cabezal magnético del PinPad (94) equivalente a pasar la tarjeta magnética, y un activador teclado PinPad (98), actúa sobre el teclado marcando las teclas del teclado del PinPad (94), simulando una transacción del usuario, estas acciones son recibidas por el PinPad (94) que envía la información correspondiente al microcontrolador (130). El activador teclado PinPad (98) (que no se muestra), es una disposición de solenoides en forma paralela y vertical entre ellos, en una superficie coincidente con la del teclado del PinPad (94), de modo que cada solenoide puede ser desplazado verticalmente para presionar la tecla bajo su posición, con lo cual se pueden emular las acciones que hace el usuario en un PinPad conectado a un POS (20) en el servicio de atención al cliente, por ejemplo, en una tienda de retail. El microcontrolador (130) envía una señal de control mediante una puerta GPIO, tanto a la interfaz cabezal magnético (96) como al activador teclado PinPad (98).  A detailed block diagram of the automation and processing apparatus (80) is shown in Figure 4, the processing unit (120) can control which fiscal card (82.83) is switched for testing, via link (141) acting on said switch (84); An interface (140) adapts the electrical signals that a microcontroller (130) receives / transmits with the chosen fiscal card (82.83), based on an application program that executes this microcontroller (130). The microcontroller (130) interacts with the PinPad (94) through the second RS232 interface (131), where the PinPad interface (92) emulates the action of a user, through a magnetic head interface that delivers a signal to the head PinPad magnetic (94) equivalent to passing the magnetic card, and a PinPad keyboard activator (98), acts on the keyboard by marking the keys of the PinPad keyboard (94), simulating a user transaction, these actions are received by the PinPad (94) that sends the corresponding information to the microcontroller (130). The PinPad keyboard activator (98) (not shown), is a parallel and vertical solenoid arrangement between them, on a surface coinciding with that of the PinPad keyboard (94), so that each solenoid can be displaced vertically to press the key under its position, which can emulate the actions that the user does in a PinPad connected to a POS (20) in the customer service, for example, in a retail store. The microcontroller (130) sends a control signal via a GPIO gate, both to the magnetic head interface (96) and to the PinPad keyboard activator (98).
En una segunda modalidad de la invención, como se muestra en la figura 5, en el aparato de automatización y procesamiento (80) la unidad de procesamiento (120) se compone de un primer microcontrolador (130') y un segundo microcontrolador (130") el cual se encarga de emular a todos los periféricos de entrada y salida del POS (20) conectados al bus (49) del POS (20), en su versión del arte previo como se muestra en la figura 1, que se realiza mediante el bus del enlace (49), entre estos periféricos se encuentra la impresora (25), pantalla usuario (29), scanner (27), etc.; se incluyen en este ejemplo una tarjeta fiscal A (82) y una tarjeta fiscal B (83), donde el segundo microcontrolador (130") a través de una salida GPIO, selecciona con cual tarjeta fiscal (82,83) operará. El segundo microcontrolador (130"), interactúa tanto con el POS (20) como con la tarjeta fiscal (82,83) seleccionada a través de una segunda interfaz RS485 (140). El programa de aplicación del segundo microcontrolador (130"), recibe y almacena la información que transmite el POS (20) hacia los periféricos de salida, por ejemplo la pantalla usuario (29), y responde al POS (20) toda la información solicitada tal como si la pantalla usuario (29) estuviese conectada al POS (20), siguiendo un protocolo de comunicaciones conocido. El PC (70), es el encargado de manejar la funcionalidad del sistema completo, para ello, envía periódicamente un comando de interrogación al primer microcontrolador (130'), el cual retransmite, a través de su puerta COMMO que se comunica con la puerta COMM2 del segundo microcontrolador (130"), la misma pregunta hacia el segundo microcontrolador (130"). Cuando el segundo microcontrolador (130") recibe el comando de interrogación desde el PC (70), transmite hacia el PC (70) ordenadamente todo lo que ha recibido desde el POS (20) al emular los periféricos de salida del POS (20), y también lo que trasmitió (si es que está siendo usada) la tarjeta fiscal A (82) o fiscal B (83) en operación. Si el segundo microcontrolador (130") no tiene nada que transmitir, informa esta condición al microcontrolador (130') el cual verifica si tiene información asociada al PinPad (94) que transmitir al PC (70); si tiene el microcontrolador (130') información que transmitir la envía al PC (70), si no tiene algo que transmitir, informa dicha condición al PC (70). El PC (70) selecciona a cual de los dos microcontroladores (130',130") debe transmitir un mensaje a través de un identificador que se incluye en una trama de datos generada por el PC (70). El PC (70) de esta manera puede interactuar con el PinPad (94) a través de la interfaz PinPad (92) y también con el microcontrolador (130") para informarle lo que debe enviar al POS (20) al emular los periféricos de entrada del POS. Por ejemplo hacer creer al POS (20) que un scanner (27) leyó un código de barras específico. In a second embodiment of the invention, as shown in Figure 5, in the automation and processing apparatus (80) the processing unit (120) is composed of a first microcontroller (130 ') and a second microcontroller (130 " ) which is responsible for emulating all the input and output peripherals of the POS (20) connected to the bus (49) of the POS (20), in its previous art version as shown in Figure 1, which is done by the link bus (49), among these peripherals is the printer (25), user screen (29), scanner (27), etc .; this includes a fiscal card A (82) and a fiscal card B (83), where the second microcontroller (130 ") through a GPIO output, selects which fiscal card (82.83) it will operate with. The second microcontroller (130 ") interacts with both the POS (20) and the fiscal card (82.83) selected through a second RS485 interface (140). The application program of the second microcontroller (130"), receives and stores the information transmitted by the POS (20) to the output peripherals, for example the user screen (29), and responds to the POS (20) all the requested information as if the user screen (29) was connected to the POS (20), following a known communications protocol. The PC (70), is responsible for managing the functionality of the complete system, for this, periodically sends an interrogation command to the first microcontroller (130 '), which relays, through its COMMO door that communicates with the door COMM2 of the second microcontroller (130 "), the same question to the second microcontroller (130"). When the second microcontroller (130 ") receives the interrogation command from the PC (70), it transmits to the PC (70) neatly everything it has received from the POS (20) when emulating the POS output peripherals (20) , and also what transmitted (if it is being used) the fiscal card A (82) or fiscal B (83) in operation. If the second microcontroller (130 ") has nothing to transmit, report this condition to the microcontroller ( 130 ') which verifies if it has information associated with the PinPad (94) to transmit to the PC (70); If you have the microcontroller (130 '), the information to transmit is sent to the PC (70), if you do not have something to transmit, report that condition to the PC (70). The PC (70) selects which of the two microcontrollers (130 ', 130 ") should transmit a message through an identifier that is included in a data frame generated by the PC (70). The PC (70) of This way you can interact with the PinPad (94) through the PinPad interface (92) and also with the microcontroller (130 ") to inform you what you should send to the POS (20) when emulating the POS input peripherals. For example, make the POS (20) believe that a scanner (27) read a specific barcode.
Cuando el POS (20) requiere interactuar con el PinPad (94), transmite un mensaje, que es capturado por el primer microcontrolador (130') y retransmitido hacia el PinPad (94). De esta manera el primer microcontrolador (130') sabe cuándo el PinPad (94) está esperando que el usuario pase la tarjeta magnética por el cabezal magnético del PinPad (94) o está esperando que se ingrese una clave a través del teclado del PinPad (94). Esta información es transmitida hacia el PC (70). Como respuesta el PC (70) transmite hacia el primer microcontrolador (130') una o las dos de las siguientes instrucciones:  When the POS (20) requires interacting with the PinPad (94), it transmits a message, which is captured by the first microcontroller (130 ') and retransmitted to the PinPad (94). In this way the first microcontroller (130 ') knows when the PinPad (94) is waiting for the user to pass the magnetic card through the magnetic head of the PinPad (94) or is waiting for a key to be entered through the PinPad keyboard ( 94). This information is transmitted to the PC (70). In response, the PC (70) transmits one or both of the following instructions to the first microcontroller (130 '):
- La información de una tarjeta magnética que deberá ser generada a través de los enlaces (93,95) que maneja el primer microcontrolador (130'), emulando que el usuario pasó una tarjeta magnética;  - The information of a magnetic card that must be generated through the links (93.95) handled by the first microcontroller (130 '), emulating that the user passed a magnetic card;
- La información de los dígitos que deben ser pulsados en el teclado del PinPad (94), a través del enlace (99) que comanda el activador de teclado (98).  - The information of the digits that must be pressed on the PinPad keyboard (94), through the link (99) commanded by the keyboard activator (98).
Cuando el POS (20) envía la señal de apertura del cajón de valores (22), esta es capturada por el primer microcontrolador (130') que informa dicha situación al PC (70), el que puede comandar al primer microcontrolador (130') que active o no active la salida de estatus que le indica al POS (20) que el cajón de valores (22) fue abierto.  When the POS (20) sends the opening signal of the value drawer (22), it is captured by the first microcontroller (130 ') that informs said situation to the PC (70), which can command the first microcontroller (130' ) that activates or does not activate the status output that indicates to the POS (20) that the value drawer (22) was opened.
En el PC (70) se dispone de un método para procesar diversas pruebas funcionales que se realizan mediante un conjunto de aplicaciones, que son: un gestor de pruebas (71) que es el encargado de la administración, mantención y almacenamiento de los casos de pruebas, planes, ciclos y métricas de pruebas; un POS Virtual para ejecución (72) y un POS Virtual para aprendizaje (73), que permite la comunicación con el aparato de automatización y procesamiento (80) y permite virtualizar los dispositivos que normalmente están conectados al POS (20); y un gestor de incidencias (74) que permite administrar, mantener y hacer seguimiento a cada una de las incidencias reportadas en las pruebas regresivas.  In the PC (70) there is a method to process various functional tests that are performed through a set of applications, which are: a test manager (71) who is responsible for the administration, maintenance and storage of cases of tests, plans, cycles and test metrics; a Virtual POS for execution (72) and a Virtual POS for learning (73), which allows communication with the automation and processing apparatus (80) and allows virtualizing the devices that are normally connected to the POS (20); and an incident manager (74) that allows to manage, maintain and monitor each of the incidents reported in the regressive tests.
En la figura 6 se describe el método de operación del aparato de automatización y procesamiento (80) para procesar pruebas funcionales de nuevas aplicaciones que se incorporan en el POS (20). Se define una etapa que consiste en crear carpetas de pruebas (1), que permite contener los casos de prueba para su definición en una base de datos en el gestor de pruebas (71); la etapa siguiente se crea un plan de pruebas (2) para el gestor de pruebas (71); la etapa que sigue se crea un ciclo de pruebas (3) para el gestor de pruebas (71); la siguiente etapa asigna el ciclo de pruebas (3) con el plan de pruebas (2); a continuación en la etapa siguiente se crean métricas (5), en base a definir un porcentaje de aceptación para los casos de pruebas (6) que se definen según la importancia de estos mismos; la definición de los casos de prueba (6) se realizan en el gestor de pruebas (71); En la etapa siguiente consiste en agregar los casos de pruebas (7) que están contenidos en la carpeta de pruebas (1) al plan de pruebas (2). A continuación se sincroniza (8) con la aplicación POS Virtual de aprendizaje (72) y la aplicación POS Virtual de ejecución (73), las carpetas que se hayan definido en el gestor de pruebas (71). Luego, se selecciona un plan de pruebas (9) en la carpeta que contiene el caso de prueba (6) que se requiere aprender. La etapa de aprender un caso de pruebas (10) permite que el aparato de automatización y procesamiento (80) aprenda las entradas y salidas de una transacción que se realiza en el POS (20), en base a ejecutar un caso de prueba y almacenar casos de pruebas (11) en esta secuencia aprendida, en la base de datos del gestor de pruebas (71); la etapa de aprender un caso de pruebas (10) y la etapa de almacenar los casos de pruebas (llj corresponden a un proceso donde el método aprende de las entradas y salidas de una transacción en la aplicación del POS (20), en base a ejecutar un caso de prueba (6) y grabar esta secuencia aprendida automáticamente, en la base de datos del gestor de pruebas (71); se registran las entradas y salidas, las cuales provienen desde el aparato de automatización y procesamiento (80). De la etapa de aprender un caso de pruebas (10) se continua con la etapa de sincronizar con el gestor de pruebas (12); a continuación sigue la etapa de seleccionar el ciclo (13) asociado para el plan que se desea ejecutar, y se realiza el seleccionar el plan de pruebas (14) a ejecutar. Luego la etapa de ejecutar (15) un caso de prueba (6) de manera aislada o un plan de pruebas (2); a continuación se puede ir a la etapa ver resultados de pruebas (18), en donde, una vez ejecutado el plan de pruebas (2), se pueden visualizar los reportes en el gestor de pruebas (71) que muestran los resultados de los casos que pasan, fallan o se bloquean. Figure 6 describes the method of operation of the automation and processing apparatus (80) for processing functional tests of new applications that are incorporated into the POS (20). A stage is defined that consists of creating test folders (1), which allows the test cases to be contained for definition in a database in the test manager (71); The next stage creates a test plan (2) for the test manager (71); the next step creates a test cycle (3) for the test manager (71); the next stage assigns the test cycle (3) with the test plan (2); then in the next stage, metrics (5) are created, based on defining a percentage of acceptance for the test cases (6) that are defined according to their importance; the definition of the test cases (6) are carried out in the test manager (71); The next stage involves adding the test cases (7) that are contained in the test folder (1) to the test plan (2). The synchronization (8) is then synchronized with the Virtual POS application for learning (72) and the Virtual POS application for execution (73), the folders defined in the test manager (71). Then, a test plan (9) is selected in the folder containing the test case (6) that is required to learn. The step of learning a test case (10) allows the automation and processing apparatus (80) to learn the inputs and outputs of a transaction that is carried out in the POS (20), based on executing a test case and storing test cases (11) in this learned sequence, in the database of the test manager (71); the stage of learning a test case (10) and the stage of storing the test cases (llj correspond to a process where the method learns from the inputs and outputs of a transaction in the application of the POS (20), based on executing a test case (6) and recording this automatically learned sequence, in the database of the test manager (71); the inputs and outputs are recorded, which come from the automation and processing apparatus (80). From the stage of learning a test case (10) the step of synchronizing with the test manager (12) is continued, then the stage of selecting the associated cycle (13) for the plan to be executed is followed, and the test plan (14) is selected to Then run the stage of executing (15) a test case (6) in isolation or a test plan (2), then you can go to the stage to see test results (18), where, once Once the test plan has been executed (2), the reports can be displayed in the test manager as (71) that show the results of cases that pass, fail or are blocked.
De la etapa de ejecutar (15) se puede continuar a la etapa registrar incidencias (16), en donde, si el aparato de automatización y procesamiento (80) registra una diferencia de entradas y salidas, registradas en la aplicación POS Virtual de aprendizaje (72), con respecto a la aplicación POS Virtual de ejecución (73), se registra la diferencia como una incidencia en el gestor de incidencias (74). La etapa de ejecutar (15) y la etapa registrar incidencias (16) corresponden a un proceso que permite realizar la ejecución de planes de pruebas (2) en forma continua, programada y desatendida. Todas las incidencias que se detectan son registradas en el gestor de incidencias (74). Los resultados obtenidos con los casos de pruebas (6) ejecutados son registrados en el gestor de pruebas (71). La etapa gestionar incidencias (17), que viene de la etapa de registrar incidencias (16), genera reportes de incidencias detectadas en el proceso de pruebas. Cada incidencia se gestiona hasta cerrarse en el gestor de incidencia (74).  From the stage of executing (15) you can continue to the stage of recording incidents (16), where, if the automation and processing apparatus (80) records a difference of inputs and outputs, registered in the Virtual Learning POS application ( 72), with respect to the Virtual POS application of execution (73), the difference is recorded as an incident in the incident manager (74). The stage of executing (15) and the stage of recording incidents (16) correspond to a process that allows the execution of test plans (2) in a continuous, programmed and unattended manner. All the incidents that are detected are registered in the incident manager (74). The results obtained with the test cases (6) executed are registered in the test manager (71). The incident management stage (17), which comes from the stage of recording incidents (16), generates reports of incidents detected in the testing process. Each incident is managed until it is closed in the incident manager (74).
El método en su conjunto permite aprender de la operación en base a pruebas funcionales definidas, basadas en casos de pruebas que se realizan en el POS (20). Una vez que el método permite aprender de los casos de prueba ejecutados en la aplicación en el POS (20), queda en posición de realizar pruebas de regresión, es decir permite verificar en forma automática, programada, permanente y continua que el comportamiento funcional de la aplicación en el POS (20) es conocido. Esto permite verificar que las modificaciones en componentes y ambiente en el POS (20) no causaron efectos inesperados y que el sistema o componentes siguen cumpliendo con los requerimientos especificados. Por lo tanto, se puede determinar que luego de un cambio no se han introducido errores en funcionalidades que no debían cambiar.  The method as a whole makes it possible to learn from the operation based on defined functional tests, based on cases of tests performed at the POS (20). Once the method allows to learn from the test cases executed in the application in the POS (20), it is in a position to perform regression tests, that is, it allows to verify automatically, programmed, permanently and continuously that the functional behavior of The application in the POS (20) is known. This allows verifying that the modifications in components and environment in the POS (20) did not cause unexpected effects and that the system or components continue to meet the specified requirements. Therefore, it can be determined that after a change no errors have been introduced in functionalities that should not change.
