Abstract

In some embodiments, apparatuses and methods are provided herein useful to automating testing of transactions at a point-of-sale (POS) terminal. In some embodiments, a system comprises a handheld scanner including an electronic switch electrically coupled to a physical trigger of the handheld scanner, wherein the handheld scanner is configured to read a product identifier, a first display device configured to present the product identifier, the POS terminal including a second display device configured to present a transaction record for a transaction, and a control circuit configured to determine a test case to execute, determine the product identifier, cause presentation of the product identifier, transmit a signal that mimics a pull of the trigger, capture, from the second display device, an image including at least a portion of the transaction record, and analyze the image to determine whether the transaction record includes a record associated with the product identifier.

First claim

What is claimed is:

1. A system for automated testing of transactions at a point-of-sale (POS) terminal, the system comprising:
a handheld scanner, wherein the handheld scanner includes an electronic switch, wherein the electronic switch is electrically coupled to a physical trigger of the handheld scanner, and wherein the handheld scanner is configured to read a product identifier;
a first display device, wherein the first display device is configured to present the product identifier;
the POS terminal, wherein the POS terminal includes a second display device, wherein the second display device is configured to present a transaction record for a transaction at the POS terminal; and
a control circuit, wherein the control circuit is communicatively coupled to the handheld scanner, the first display device, and the second display device, and wherein the control circuit is configured to:
determine a test case to execute;
determine, based on the test case to execute, the product identifier;
cause presentation, on the first display device, of the product identifier;
transmit, to the electronic switch, a signal, wherein the signal mimics a pull of the trigger and causes the handheld scanner to read the product identifier;
capture, from the second display device, an image, wherein the image includes at least a portion of the transaction record updated by the POS terminal in response to receipt of an indication of the product identifier from the handheld scanner;
analyze the image, via one or more of optical character recognition (OCR) and image recognition, to determine whether the transaction record includes a record associated with the product identifier;
retransmit, to the electronic switch, the signal when it is determined, based on the analysis of the image, that the transaction record does not include the record associated with the product identifier; and
log, in a database, an indication of success for the test case when it is determined, based on the analysis of the image, that the transaction record does include the record associated with the product identifier.

2. The system of claim 1 , wherein the control circuit is further configured to:
after retransmission of the signal to the electronic switch, capture, from the second display device, a second image;
determine, based on an analysis of the second image, that the transaction record does not include a record associated with the product identifier; and
perform one of,
cashing out the transaction;
voiding the transaction; and
causing the POS terminal to reboot.

3. The system of claim 1 , wherein the electronic switch is a transistor.

4. The system of claim 1 , wherein the test case is one of a general merchandise item, an age restricted item, an item with which a service contract is associated, a linked transaction, and a coupon transaction.

5. The system of claim 1 , wherein the record associated with the product identifier is a line item on the transaction record.

6. The system of claim 1 , wherein the handheld scanner is further configured to:
transmit, after reading the product identifier, an indication of the product identifier to the POS terminal.

7. The system of claim 6 , wherein the POS terminal is further configured to:
in response to receipt of the indication of the product identifier from the handheld scanner, update the transaction record to include the record associated with the product identifier.

8. A method for automated testing of transaction at a point-of-sale (POS) terminal, the method comprising:
determining, by an automated testing system, a test case to execute;
determining, based on the test case to execute, a product identifier;
presenting, via a first display device, the product identifier;
transmitting, to an electronic switch incorporated with a handheld scanner, a signal, wherein the signal mimics a pull of a trigger of the handheld scanner and causes the handheld scanner to read the product identifier;
capturing, by the automated testing system, an image of a second display device of the POS terminal, wherein the image includes at least a portion of a transaction record updated by the POS terminal in response to receipt of an indication of the product identifier from the handheld scanner;
analyzing the image, by the automated testing system via one or more of optical character recognition (OCR) and image recognition, to determine whether the transaction record includes the record associated with the product identifier;
retransmitting, to the electronic switch, the signal when it is determined, based on the analysis of the image, that the transaction record does not include the record associated with the product identifier; and
logging, in a database, an indication of success for the test case when it is determined, based on the analysis of the image, that the transaction record does include the record associated with the product identifier.

9. The method of claim 8 further comprising:
after retransmitting the signal to the electronic switch, capturing, from the second display device, a second image;
determining, based on an analysis of the second image, that the transaction record does not include a record associated with the product identifier; and
performing one of,
cashing out the transaction;
voiding the transaction; and
causing the POS terminal to reboot.

10. The method of claim 8 , wherein the electronic switch is a transistor.

11. The method of claim 8 , wherein the test case is one of a general merchandise item, an age restricted item, an item with which a service contract is associated, a linked transaction, and a coupon transaction.

12. The method of claim 8 , wherein the record associated with the product identifier is a line item on the transaction record.
