Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments, and it should be noted that, in the premise of no conflict, the following described embodiments or technical features may be arbitrarily combined to form a new embodiment:

example (b):

referring to fig. 1-8, an automated testing method based on an IMS device, as shown in fig. 1, includes the following steps:

s100, establishing communication with a device to be tested; the establishing communication step comprises: sending a two-layer broadcast packet to a device side to be tested, and receiving a temporary IP address and an MAC address sent by each device to be tested on the device side to be tested;

fig. 2 is a schematic diagram of the communication between the test tool side and the device to be tested according to the present invention, where the test tool side may include one or more test tools, the test tool may be a PC of a tester, and the test tool of the present invention serves as a server and passively receives a report of the device to be tested by using TCP connection. The device to be tested comprises at least one device to be tested, and the device to be tested is IMS device.

Before the IMS device is tested, the management network port of the IMS device does not have a solidified IP address and a solidified MAC address. Therefore, in order to enable the test tool and the device under test to stably communicate within a certain test period, the device under test will randomly generate the currently used IP address and MAC address. The IP address is randomized with only the lower 24 bits, and is supplemented with a subnet mask of 255.0.0.0. For example, the device to be tested generates the IP in a form of 140.x.x.x, so that different IP combinations are provided for the device to be tested to select, and the fault tolerance of IP collision when multiple IMS devices are tested simultaneously is greatly improved. Meanwhile, with the aid of a 255.0.0.0 subnet, only the network segment of 140.x.x.x is occupied as a test network segment, and other network segments are not affected.

The temporary IP address is randomized using only the lower 24 bits.

The step of randomizing the lower 24 bits includes:

In order to enable the device to be tested to know and connect the IP address of the test tool, the test tool periodically sends a two-layer broadcast packet carrying the IP address and the TCP port to the current test network segment. The schematic structural diagram of the two-layer broadcast packet of the present invention is shown in fig. 3, and the two-layer broadcast packet is set as follows: the destination MAC address of the two-layer broadcast packet is set as a broadcast address, and the protocol type is fixed to 0x 9955. After receiving the broadcast packet, the IMS device generates a temporary IP address and an MAC address to communicate with the test tool, so that the test tool side and the device to be tested establish communication.

Preferably, the present invention further comprises the steps of: after communication is established with the side of the equipment to be tested, the unique virtual serial number of each piece of equipment to be tested in the side of the equipment to be tested is set. The virtual serial number comprises the MAC address of the PC where the test tool is located, the current test time and the self-increment value. A device under test is produced from it to the customer, possibly over multiple tests. However, for the test tool, a certain device under test does not have an identifiable identifier before the actual serial number is solidified, that is, even if the device under test is reported, the test tool does not know whether the device under test has been tested before, and how the test result is. For this purpose, the uniqueness of each device under test can be determined by setting a virtual serial number.

Specifically, in an actual test environment, a tester will use its own PC as a load of a test tool, and the IMS device to be tested will also be connected to the PC, and meanwhile, a plurality of testers will perform tests simultaneously. In order to ensure that the identifier of each device to be tested is unique, the MAC of the PC where the current testing tool is located is mutually exclusive, so that the communication is ensured not to be disordered) + the current testing time (the uniqueness of different time periods on the same PC is ensured) + the self-increment value (the initial value is 0 and 1 is added to each device to be tested reported so as to ensure the uniqueness of the device to be tested in the same time). The unique mark generated in this way is called a virtual serial number, once the device to be tested with the virtual serial number is taken, the device to be tested with the virtual serial number is solidified into a local FLASH to be stored, and then all interactions with the testing tool report the virtual serial number. The test tool will also use the virtual serial number as the identification code of the device under test.

The following are examples of three groups of virtual sequence numbers:

00195B7F2A4B 190CF23B 00001

00195B7F2A4B 190EB24A 00050

00195B7F2A4B 190EEC75 00112

for convenience, the virtual serial number is divided into three segments according to the MAC address, the test time and the self-increment. The first segment is the MAC address (16 system) of the current PC, the current test time is mainly based on the time reported by the equipment to be tested, and the original 32-bit 2 system time (millisecond level) is converted into 8-bit 16 system, so as to shorten the length of the virtual serial number. The self-increment value of the third section adopts a 5-bit 10-system counting mode. And finally, splicing the three sections in a character string mode to form a virtual serial number.

S200, performing test data interaction with a device to be tested; and respectively sending test requirement data corresponding to each device to be tested, and receiving test result data returned by each device to be tested. The test requirement data is command data for performing a function test on the equipment to be tested, and the test result data is test result data after the equipment to be tested is analyzed and operated based on the test requirement data.

Preferably, the test data interaction between the test tool side and the device to be tested adopts a TCP packet with a scalable length, and the scalable TCP packet is a variable length TCP packet, and includes: the command data includes a command identifier, a command code, and a command parameter column, wherein the command parameter column includes parameter lengths and parameter values of a plurality of parameters.

The test tool assembles the command codes representing the test requirement data according to the mode and issues the command codes to all the devices to be tested. The device to be tested carries out reverse disassembly command on the form of the test required data, initializes the test environment of the device to be tested according to the parameter values, and feeds back the test result data to the test tool in the form of TCP packets after the test of the device to be tested is finished. The test requirement data may specifically include test results, test-related description information, and the like.

If the device under test and the test tool communicate normally, the test tool loads the test instructions along with the test parameters into the command parameter portion of the data under test. After the device to be tested analyzes and processes the test requirements, when the partial item test is finished, the device to be tested loads the command parameter part in the test results according to the requirements of the TCP variable-length packet and the results and the description of the test items, and reports the command parameter part to the test tool. The test results contained only two states: success and failure. In the event of a failure, the result description is accompanied by failure information for the tester to review.

Preferably, the test method of the present invention may formulate test template data for the test requirement data according to the type of the device to be tested and the test requirements. Due to the scalability of the variable length TCP packet, the test tool can easily assemble various test commands according to the function. For such convenience, the test tool opens up the function of the test template. The tester can flexibly select the test functionality according to different types and different test requirements of the equipment to be tested, and the test functionality is customized into a template which is persistently managed by the test tool so as to be reused later.

Specifically, the functional items to be tested generally include the following points:

1) memory device

2)FLASH

3)USB/SD

4) Push-button

5) FXS/FXO port

6) Net mouth

7) Light port

8)WIFI

9)SIM/LTE

10) Software version

11) Target user

12) Automatic upgrade

13) MAC/SN allocation

14) General inspection

Wherein it is noted that

1) An interactive process exists in the testing process of the WIFI, the network port, the optical port and the FXS/FXO port (namely, the port sends data, and a receiver receives and feeds back the data). Therefore, when testing these several functions, an additional device under test is required as a receiver.

2) MAC/SN allocation and gross inspection can only be tested after other tests are completed and successful.

3) Automatic upgrade requires a TFTP/HTTP server to enable the transfer of the upgrade file.

4) The test of the key-press requires the tester to manually press the key-press to be tested on the device to be tested

5) Other test items only need to be sent to the interior of the equipment to be tested for testing.

The tester can select several items from the above function items as the test flow of the current test, or store the several items as templates for use by other testers or later.

For example, for an IMS device, the stock functions include five items, namely, a memory, a FLASH, a key, an FXS/FXO port, and a network port, and the five items can be combined into a general test template to meet basic test requirements of the IMS device.

For another example, the three items of software version, target user, and automatic upgrade are basic maintenance items, and a client may frequently change the version, currently used user name, patch, and the like of the device under test. For this reason, these three items can be combined into a common maintenance item template to cope with frequent maintenance needs.

And the MAC/SN allocation and the total check are carried out after all the items are successful. The completion of these two terms also represents the device under test to be sent to the customer for use. Therefore, the two items can be said to form a final test template for final production initialization.

The MAC/SN assignment will solidify the actual serial number and MAC address of the device under test (the actual serial number and MAC address may change). The test tool counts success conditions of other function items except MAC/SN distribution and general inspection (if the function items are included) in the test period every time the device to be tested reports the test result, once the requirements are met, the test tool opens an MAC/SN distribution inlet for a tester to input an actual serial number, and meanwhile searches a corresponding MAC address in a file (the tester is prepared in advance) under a corresponding path of a PC through the actual serial number, sends the MAC address to the device to be tested, and jumps to the next device to be tested which can distribute the MAC/SN. In the process, only one action of scanning the bar code (the bar code containing the actual serial number) is needed by a tester, and the MAC/SN distribution can be carried out on the device to be tested. Compared with the prior art, the process of continuously and repeatedly operating the mouse and the keyboard is avoided.

The final step of the overall test flow (if including the function item). After the MAC/SN is successfully distributed, the general inspection initializes all data of the equipment to be tested so as to achieve the purpose of being used by a client.

As another preferred embodiment, the present invention further comprises the steps of: and carrying out persistence processing on various types of data generated in the testing process through a persistence tool.

Fig. 8 is a schematic diagram of a system structure of an IMS device-based automated testing method, which includes a plurality of devices under test and a plurality of testing tools, where the devices under test communicate with one testing tool, and each testing tool performs a persistence operation on the testing process through a persistence tool.

The device to be tested which needs to be tested takes the virtual serial number as the unique identification of the device. A device under test may be tested multiple times from production to delivery to a customer. The test life of the whole device to be tested can be well recorded by using the unique identifier. The testing tool conducts persistence operation on the testing process through the persistence tool so as to facilitate query of testing personnel at any time.

Specifically, the persistence tool used by the testing tool may be a MySql database. The MySql database is a typical relational database, and realizes reading and writing of data by analyzing SQL statements. Generally, the execution of the SQL statement is divided into three layers:

1. and the connection layer is responsible for providing a connection protocol, verifying functional identity information and providing a special connection thread.

And the SQL layer is responsible for verifying, analyzing and optimizing the SQL statement and submitting the SQL statement to the next layer for processing. Or receive data from the next layer delivery.

3. And the storage engine layer extracts data according to the requirements of the SQL layer and re-submits the data to the SQL layer.

The SQL statement and result set are transmitted between the test tool and MySql through a TCP connection, as shown in FIG. 5.

SQL statements usually take the form of strings, e.g., a column of data is obtained from the MySql table, select < param1> from < table >. The result set is a binary stream that can be parsed into the required data by a parser internal to the test tool. Similarly, the Sql statement may also store data that needs to be persisted in a disk managed by MySql, for example, the following statements: insert < table > < param1> < param 2.. values < value1> < value 2.. values 1 for parameter 1 and values 2 for parameter 2 are combined into a record and stored. In many cases, an IMS device needs to be upgraded to a corresponding version to communicate and test with the test tool.

Referring to fig. 7, an automated testing method based on IMS devices is shown, where in fig. 7, the devices are all devices under test, and the method includes the following steps:

step S1000, establishing communication with a testing tool side; the establishing communication step comprises: receiving a two-layer broadcast packet sent by a testing tool side, and sending a temporary IP address and an MAC address of a device to be tested to the testing tool side;

s2000, carrying out test data interaction with a test tool side; each device to be tested receives the corresponding test requirement data, processes the test requirement data and returns test result data to the test tool side;

and S3000, sending out a signal prompt by each device to be tested based on the test state of the device to be tested.

Specifically, the test states include three states of being tested, passing the test, and failing the test. The sequence of reporting IMS devices to a test tool is random, and since a tester may test multiple devices under test at the same time, a way to conveniently locate a certain number of devices under test or devices under test in different states is needed in the test process. For the tester, the most intuitive way is to light the device to be tested. In the whole test process, a certain group of lamps of the IMS device (the specific situation depends on the type of the device to be tested, but the number of lamps participating in the state determination may exceed three) may represent different states in the following ways:

1) the group of lamps of the equipment to be tested is completely extinguished;

2) the group of lamps of the equipment to be tested passing the test are periodically turned on and off;

3) the group of lamps of the equipment to be tested which is not passed through the test is fully lighted;

4) the group of equi-horses flash when the device to be tested is selected.

The method can be used for the tester to pick the specified device to be tested well and conveniently.

In specific applications, the information displayed on the test interface of the test tool can be as shown in fig. 6, and includes an equipment display area, a test result display area, and a test result statistical area, where the equipment display area displays parameter data of the device to be tested, the test result display area displays test result data, and the test result only includes two states: success and failure. In the event of a failure, the test result data includes a description with failure information attached for review by the tester.
