Detailed Description
The technical scheme of the invention is further explained by combining the drawings and the embodiment.
Referring to fig. 1, the invention first discloses an automated testing system of a container terminal quay crane management system, which is written in C # language for an automated testing platform of a container terminal quay crane management system (QCMS for short) in a simulation environment. As shown in fig. 1, the system of the present invention mainly includes: the system comprises an automatic test platform 1, a test case 2, a database 3, a QCMS 4, an OPC5 and a shore bridge simulation device 6.

OPC (OLE for Process Control ) is an industry standard, the establishment of which is based on microsoft com (component Object model) specification and is managed by the OPC foundation, an international organization. It provides a standard data access mechanism for the industrial manufacturing field. OPC defines a standard interface for hardware devices, software and systems of different manufacturers, so that different hardware devices (such as PLC, board card, smart meter, frequency converter, etc.) and third party software systems in process control and factory automation can be connected, communicated and operated conveniently. Before the OPC interface is adopted, a software system needs to communicate with different hardware devices depending on different drivers and the connection is complex. After the OPC interface is adopted, the communication with different devices can be easily realized only by providing a standard OPC interface.
According to the functional requirements, the tester only needs to write the test case according to the format agreed in advance by the test system of the invention and store the test case as a common CSV file. The CSV is a comma-separated text file, and the file stores table data (numbers and texts) in a pure text form, so that the CSV file can be conveniently edited, generated and viewed in the EXCEL. The test system can automatically analyze the test case, extract the task information in the case, send the task information to the database, monitor the relevant state of the task in the execution process, compare the task information with the expected result of the case, and finally output the test result. The testing system simulates some important functions of TOS, such as task sending, platform OCR confirmation and the like, so that the testing system of the invention is attached to a testing environment without the participation of TOS, and only needs a database, OPC, a shore bridge equipment simulator and a tested object QCMS.
The specific functions of the above-mentioned several main modules are described as follows:
1) a use case information reading module: and the CSV case is responsible for reading the information in the CSV case and storing the information for other modules to use.

The technical solution of the present invention is further specifically described below by an embodiment with reference to fig. 1.
First, before the automated testing begins, the relevant simulation testing environment is prepared. The test environment comprises a tested object QCMS 4, OPC5, a database 3 and a shore bridge equipment simulator 6. In addition, the test case 2 needs to be prepared, and the configuration file of the automatic test platform 1 needs to be configured. The configuration file contains information in the test environment so that the automated test platform 1 knows how to contact the environment. After the automatic test platform 1 is started, information such as OPC5 and database 3 is read from the configuration file, and then communication connection is established with the information. The automated test platform 1 then performs an initialization test environment to prepare for the next execution of the use case.
After the test environment is initialized, the automatic test platform 1 acquires the path of the test case 2 from the configuration file, the case information reading module 11 of the automatic test platform 1 starts to read the information in the CSV case, and analyzes the case information according to a predetermined format and stores the case information for other modules.
As an implementation manner of this embodiment, the double-trolley shore bridge includes two trolleys, i.e., a main trolley and a gantry trolley, mt is agreed in advance to represent the main trolley, and pt represents the gantry trolley. If the type of a certain test case 2 is the updating of a test box placing target position, one case is that the TOS sends a ship unloading task, the target position is the AGV, and when the main trolley carries out a ship box grabbing instruction, the TOS changes the target position of the task into a collection card.
Besides the ship unloading task information, the test case 2 designed by the tester also contains the following key test information: the update time, the update target position and the expected target position correspond to the test time, the test action and the expected result, respectively. According to the convention, the updating time of the case is set to be mt-PickuPship, mt indicates that the case is a main car, and PickuPship indicates that the case is grabbed on the ship. The update target position and the expected destination position are both set to true, representing a card concentrator.
After the use case information is read and analyzed by the use case information reading module 11, the information is delivered to the use case information processing module 12 for processing. The use case information processing module 12 firstly writes ship unloading task information into the database 3, at the moment, the QCMS 4 starts executing tasks, then the use case information processing module 12 transmits update time information to the task state monitoring module 13 of the platform, the task state monitoring module 13 starts threads, state information of shore bridge equipment in the OPC5 and state information of tasks in the database 3 are read at a certain frequency, and when the main trolley is monitored to carry out a PickupShip instruction, event information is transmitted to the use case information processing module 12 in an event notification mode. After receiving the event notification, the use case information processing module 12 updates the task target location in the database 3 to true. The task state monitoring module 13 continues to work, and when the state of the task in the database 3 is monitored to be completed, the actual final box placing position of the task is obtained and transmitted to the use case information processing module 12.
The case information processing module 12 transmits the actual final box placing position information, the expected box placing position information in the test case 2 and the related information in the task execution process to the test report generating module 14, and the test report generating module 14 generates the test report. The test report generation module 14 generates the test result of the test case 2 according to the information, and also outputs the relevant information in the task execution process for the tester to use as reference when the case test fails.
In summary, the present invention has the following advantages:
1: the use case is automatically executed, the tester does not need to participate in the whole process, and the testing efficiency is very high.
2: the test case is in the csv format, so that a tester does not need programming experience, and the platform is very simple to use.
3: is suitable for regression testing. When the version is updated and tested each time, for example, the function requirements related to the use case are not changed, the use case does not need to be changed, and the test can be automatically run directly.
4: the condition of making mistakes due to artificial subjective judgment can be avoided.
5: some cases which cannot be executed or are difficult to execute manually due to high time requirements and the like can be tested.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
