detailed description

Hereinafter, the principle of the present invention will be described with reference to the embodiments. It should be understood that the given examples are only for those skilled in the art to better understand and practice the present invention, rather than limiting the scope of the present invention. For example, the inclusion of many specific implementation details in this specification should not be construed as limitations on the scope of the invention or of what may be claimed, but rather as descriptions specific to the embodiments. For example, features that are described in the context of separate embodiments can be implemented in combination in a single embodiment. Features described in the context of a single embodiment can be implemented in multiple embodiments.

Fig. 1 is a schematic diagram of a card swiping transaction through a POS terminal according to an embodiment of the present invention. As shown in Figure 1, card swiping transactions involve entities such as cards, POS terminals, acquiring systems, transfer/clearing systems (for example, bank card organizations such as UnionPay and VISA), and card issuing systems. When the cardholder swipes the card, the POS terminal reads the card information and generates a transaction message. The acquirer receives and processes the transaction message from the POS terminal, and sends the processed transaction message to the card issuer through the transfer agency. The card issuer debits the card account according to the received transaction message. After receiving the response of successful deduction, the transfer organization returns the transaction result to the POS terminal. The path of information transmission can be as shown in Figure 1, from the POS terminal to the acquiring system, then to the transfer/clearing system, and finally to the card issuing system, and the opposite path.

Various embodiments of the present invention test the acquiring system and/or card issuing system in the above transaction path. Compared with artificially designed test data, the embodiments of the present invention use real transaction data for testing to improve the accuracy and efficiency of testing. In order to facilitate testing by testers and reduce testing costs, the embodiments of the present invention expand existing POS terminals.

As shown in Figure 2, in addition to the original cash register module in the POS terminal, one or more embodiments of the present invention also set one or more of the connection module, simulation module, judgment module, and configuration module in the POS terminal . These modules may be located locally at the POS terminal, or as part of the POS terminal remotely with respect to the POS terminal entity.

According to one embodiment, the POS terminal includes: a connection module, used for connecting with the system under test; a simulation module, used for interacting with the system under test; and a judging module, used for judging the test result according to the result of the interaction. The connection module is connected with the system under test through the network. The simulation module is used to simulate the system in one or more transaction paths to interact with the system under test. The judging module can judge the test result according to the predetermined condition.

Optionally, the POS terminal may also include a configuration module for configuring test parameters, such as test input, execution conditions and expected results, and parameters of the system to be tested.

In different embodiments, the system under test may be an acquiring system, a card issuing system, or both. The acquiring system may be any software system, software module, or specific code related to the acquiring institution or within the acquiring institution. The card issuer system can be any software system, software module, or specific code related to the card issuer or within the card issuer.

The test process can be simplified by simulating other software systems in the transaction process except the POS terminal and the system to be tested through the simulation module. In particular, setting the simulation module on the POS terminal can simplify the test operation and save the test cost. Testers only need to operate the POS terminal for testing.

Fig. 3 is a schematic diagram of testing an acquiring system using a POS terminal according to an embodiment of the present invention. In this embodiment, the system under test includes an acquirer system. The card and the cash register module of the POS terminal generate a transaction message, which is sent to the acquiring system by the cash register module. This process produces real transaction data. Afterwards, the acquired system under test sends the processed transaction message to the simulation module. The simulation module can generate a response message according to the configuration of the test case, and return it to the acquiring system. The response is returned to the judging module in the POS terminal via the acquiring system. With the help of the simulation module, the transaction process is completed to achieve the purpose of testing the acquiring system. Specifically, during the testing process, the connection module is configured to send transaction messages to the acquiring system, the simulation module is configured to receive transaction messages processed by the acquiring system, and generate response messages, and the judging module is It is configured to judge the test result of the acquiring system based on the response message.

According to this embodiment, the testers for the acquiring system only need to use the POS terminal to test the acquiring system.

Fig. 4 is a schematic diagram of a card issuing system tested by using a POS terminal according to an embodiment of the present invention. In this embodiment, the system under test includes a card issuing system. The card and the cash register module of the POS terminal generate a transaction message, which is sent to the simulation module by the cash register module. This process produces real transaction data. Afterwards, the simulation module simulates the acquiring system to receive the transaction message from the POS terminal, and simulates the switching system to send the processed transaction message to the card issuing system under test. After processing the transaction message, the card issuing system returns a response message to the POS terminal through the original transaction path. Specifically, during the test, the connection module is configured to send transaction messages to the simulation module, and the simulation module is configured to preprocess the transaction messages and send the preprocessed transaction messages to the card issuing system The judging module is configured to judge the test result of the card issuing system based on the response message generated by the card issuing system.

In this embodiment, using real cards and transactions produced by real POS terminals can avoid inaccurate test results caused by simulated cards and simulated terminals.

As mentioned above, one or more of the emulation module, judgment module, and configuration module can be remotely set relative to the POS terminal entity as a part of the POS terminal. For example, one or more of the simulation module, judgment module and configuration module are deployed on the cloud of the POS terminal. The functions of these modules or one or more steps to be performed by these modules can be dynamically extended to the Internet based on cloud computing technology, and computing can be completed using virtual resources on the Internet.
