The prior art method is described first, and then the technical solution of the present application is described in detail.

Before a network device is put into use, it is necessary to comprehensively test various aspects of the configuration, functions and the like of the device to verify whether the configuration and functions of the device can achieve a desired result. Taking an industrial gateway as an example, many test case design methods of the industrial gateway at present are all designed by using a full black box according to protocol functions, such as equivalence class division, a boundary value method, and the like. The use case input designed by the method is many. However, many product problems in practical application are hidden deeply, and especially, in the case of abnormal testing under the condition of multi-input variable combination, the industrial gateway cannot be tested comprehensively within a limited time.

The prior art has the following defects: the designed cases are input in a plurality of ways, and the industrial gateway cannot be comprehensively tested within a limited time. The function is not tested in place, so that the safety problem of the use of the industrial gateway can be caused, and an application platform is damaged.

Based on the technical problems in the prior art, the application provides a method for generating a device test case. The method designs a processing flow by taking the configuration input variables in the configuration information as a reference, generates an equipment test case aiming at each independent path of a processing flow chart, and can find out the full-path test case of the relevant configuration input variables, thereby using a small number of equipment test cases to cover more tests, achieving higher test efficiency, and solving the problems of insufficient test and equipment safety in the prior art.

Fig. 1 is a schematic diagram of an embodiment of a method for generating a device test case according to an embodiment of the present application. As shown in fig. 1, the method for generating the device test case may include:

step S110, obtaining configuration input variables from the equipment configuration information;

step S120, acquiring a processing flow chart formulated according to the configuration input variables;

step S130, determining an independent path set of the processing flow chart;

step S140, aiming at each independent path in the independent path set, obtaining an input variable combination and an expected result corresponding to the independent path;

and S150, generating an equipment test case according to the input variable combination and the expected result.

The embodiment of the application provides a black box test case generation method combined with a basic path method. Specifically, a data opposite-end receiving instrument can be provided to test whether the opposite-end receiving instrument and the device to be tested can normally communicate. In the test process, the opposite-end receiving instrument can be used as a server, and the server is set to be configured into target connection.

Taking the test of an industrial gateway as an example, the device configuration information may include information in a file such as a gateway configuration manual. From the gateway configuration manual, all configuration input variables for establishing a connection can be obtained. All configuration input variables for establishing a connection may be stored in a preset format in the gateway configuration manual in advance. For example: the preset format may include a table, a specific separator, a specific marker, and the like. In step S110, a preset format for storing configuration input variables may be identified in the device configuration information. For example, a table, a specific separator, a specific mark symbol, or the like can be recognized in a predetermined format. And then obtaining the configuration input variables stored according to the preset format. Still taking the test of the industrial gateway as an example, the configuration input variables may include a service IP (Internet Protocol) configuration, a port configuration, a public address configuration, and the like.

After the configuration input variables are obtained, a corresponding processing flow chart can be formulated according to the configuration input variables. Specifically, a serial number of each configuration input variable for establishing connection may be marked first; then, an opposite-end receiving instrument is set to set a server-end configuration as a target connection; and finally, formulating an input variable processing flow chart for establishing connection according to the sequence of the network layer, the transmission layer and the application layer. Fig. 2 is a processing flow chart of an embodiment of a method for generating a device test case according to an embodiment of the present application. As shown in fig. 2, the IP configuration and the port configuration belong to configuration input variables of a network layer, and the public address configuration belongs to configuration input variables of an application layer. Then in the processing flow chart, processing is performed first for IP configuration and port configuration, and then processing is performed for configuration input variables such as public address configuration. In step S120, a processing flowchart formulated according to the above configuration input variables is acquired. And in the subsequent processing process, generating a device test case according to the path information in the processing flow chart.

In step S130, the processing flowchart may be scanned, and the processing nodes are scanned sequentially in the processing order from the start node to the end node. Wherein the decision nodes represented by the diamonds identify different branches in the process flow. By scanning the processing flow chart, the main path and the independent path of the processing flow chart can be obtained. For example, the process flow diagram has N independent paths, and the N independent paths constitute the independent path set of the process flow diagram. In subsequent processes, each individual path in the process flow diagram may be guaranteed to be executed at least once.

In step S140, a relevant input variable combination of each device test case is obtained according to the N independent paths forming the independent path set, and an expected result of the opposite-end receiving instrument under each piece of independent path data is listed. In general, the configuration input variables are extracted from the content of the decision nodes represented by the diamonds in the independent path. Corresponding expected results can be obtained according to the configuration input variables. And combining each configuration input variable and the corresponding expected result to obtain an input variable combination and an expected result corresponding to the independent path.

In step S150, test case paths connecting the receiving instruments at the opposite end are generated one by one according to the input variable combinations and expected results obtained in step S140. And aiming at the N independent paths forming the independent path set, generating a corresponding equipment test case under each independent path.

According to the embodiment of the application, a small number of equipment test cases can be used for covering more test points, so that higher test efficiency is achieved, and the use safety of equipment is improved.

Fig. 3 is a schematic diagram of an embodiment of a method for generating a device test case according to an embodiment of the present application. As shown in fig. 3, in one embodiment, step S130 in fig. 1, the determining the independent path set of the processing flow chart includes:

step S210, determining a trunk path of the processing flow chart, where the trunk path is a path formed by branches corresponding to the first value of the determination result of the determination node in the processing flow chart;

step S220, determining a branch path of the processing flow chart, wherein the branch path comprises at least one branch corresponding to the value except the first value of the judgment result of the judgment node;

step S230, determining an independent path set of the processing flowchart according to the trunk path and the branch path.

In the embodiment of the present application, taking the power protocol IEC104 state quantity input test as an example, all configuration input variables for establishing a connection may be obtained from the IEC104 protocol configuration manual in step S110. For example, the configuration input variables may include a server IP configuration, a port configuration, a public address byte count configuration, a public address configuration, a point number configuration, a value type configuration, and the like. The IP configuration and the port configuration belong to configuration input variables of a network layer, and the public address byte number configuration, the public address configuration, the point number configuration and the value type configuration belong to configuration input variables of an application layer.

A flow chart of the process formulated according to the configuration input variables is shown in fig. 2. As shown in fig. 2, the judgment nodes represented by the diamonds include node 1, node 3, node 6, node 10, node 14, and node 18. The judgment processing executed by the judgment node shown in the node 1 is that whether the server IP is the same as the configuration of the opposite-end instrument, and the configuration input variable corresponding to the node is the server IP configuration. Similarly, the judgment processing performed by the judgment node shown in the node 3 is "whether the port is configured correctly", and the configuration input variable corresponding to the node is the port configuration. In fig. 2, the judgment nodes represented by each diamond correspond to the judgment processes executed by the configuration input variables, which are not described in detail herein.

In step S210, the first value of the determination result of the determination node may be yes. And determining the path formed by the branches corresponding to the judgment result of the judgment node in the processing flow chart as 'yes' as the main path of the processing flow chart. For example, in FIG. 2, the stem path of the process flow diagram can be determined to be 1- >3- >5- >6- >9- >10- >13- >14- >17- >18- >21- >22.

In step S220, it is determined that the other value of the determination result of the node than the first value may be "no". And determining the branch corresponding to the judgment result of the at least one judgment node as 'no' as a branch path of the processing flow chart. For example, in FIG. 2, the branch path of the process flow diagram may be determined to be 1- >2- >22. Specifically, a judgment node of the trunk path may be found according to the processing flow chart, and another independent path branch other than the trunk path is found at the judgment node, that is, the branch path.

In step S230, the trunk paths and branch paths of the processing flow chart are listed, so as to form N independent paths, which form an independent path set of the processing flow chart.

In the example shown in fig. 2, all the independent paths listed are:

route 1:1- >2- >22

Route 2:1- >3- >4- >22

Route 3:1- >3- >5- >6- >7- >8- >10- >13- >14- >17- >18- >21- >22

Path 4:1- >3- >5- >6- >9- >10- >11- >12- >14- >17- >18- >21- >22

Path 5:1- >3- >5- >6- >9- >10- >13- >14- >15- >16- >18- >21- >22

Path 6:1- >3- >5- >6- >9- >10- >13- >14- >17- >18- >19- >20- >22

Path 7:1- >3- >5- >6- >9- >10- >13- >14- >17- >18- >21- >22

The path 7 is a trunk path, and the paths 1 to 6 are branch paths. In an independent set of paths, introducing a new path should include at least a new branch that was not included in the set. Thus, each individual path in the process flow diagram can be guaranteed to be executed at least once in subsequent processes. By utilizing the independent path set, the full path test case of the relevant configuration input variable can be found out, so that more tests can be covered by using a small number of equipment test cases, and higher test efficiency can be achieved.

Fig. 4 is a schematic diagram of an embodiment of a method for generating a device test case according to an embodiment of the present application. As shown in fig. 4, in an embodiment, in step S140 in fig. 1, the obtaining, for each independent path in the independent path set, an input variable combination and an expected result corresponding to the independent path includes:

step S410, traversing each judgment node in the independent path to obtain a configuration input variable corresponding to each judgment node;

step S420, obtaining an input variable combination corresponding to the independent path according to the configuration input variable corresponding to each of the determination nodes.

For each independent path, each judgment node in the independent path can be traversed, and configuration input variables can be extracted from the content of the judgment nodes. For example, for the judgment node 1 in the path 2, the configuration input variable may be extracted from the node content "whether the server IP is the same as the peer instrument configuration". And acquiring the judgment result of the judgment node as yes, and combining the extracted service end IP configuration with the judgment result of yes to obtain the service end IP configuration which is the same as the opposite end instrument. Similarly, for the judgment node 3 in the path 2, the configuration input variable can be extracted from the node content "whether the port configuration is correct" to be the port configuration. And acquiring whether the judgment result of the judgment node is negative, and combining the extracted port configuration and the judgment result of the negative to obtain different ports. The variables are then input according to the two configurations: and (3) server IP configuration and port configuration, and finally obtaining an input variable combination corresponding to the path 2, wherein the server IP configuration is the same as that of an opposite-end instrument and the ports are different.

Fig. 5 is a schematic diagram of an embodiment of a method for generating a device test case according to an embodiment of the present application. As shown in fig. 5, in an embodiment, in step S140 in fig. 1, the obtaining, for each independent path in the independent path set, an input variable combination and an expected result corresponding to the independent path includes:

step S510, obtaining an expected result corresponding to each configuration input variable in the input variable combination according to a preset corresponding relation between the configuration input variables and the expected results;

and step S520, obtaining an expected result of the input variable combination according to the expected result corresponding to each configuration input variable.

In the embodiment of the application, the corresponding relation between the configuration input variable and the expected result can be preset. For example:

1) If the IP configuration of the server is different from that of the opposite-end instrument, the expected result is no connection display and abnormal communication of the opposite-end instrument;

2) If the ports are different, the expected result is no connection display and abnormal communication of the opposite-end instrument;

3) If the server IP and the port configuration are the same, the expected result is that the opposite-end instrument displays connection and interactive messages exist.

According to the above correspondence, a path that the judgment result of the judgment node 1 corresponding to the configuration input variable is "no" can be obtained for the service end IP configuration, and the corresponding expected result is "no connection display of the opposite end instrument, abnormal communication"; for port configuration, the path with the judgment result of the judgment node 3 corresponding to the configuration input variable being "no" also has the corresponding expected result of "no connection display to the opposite end instrument and abnormal communication"; and for the above two configuration input variables, the judgment results of the corresponding judgment nodes 1 and 3 are yes, and the corresponding expected result is 'opposite end instrument display connection with interactive message'.

For another example, if the number of bytes of the public address is configured differently, the expected result is a resolution error. Then the number of bytes of the input variable public address is configured to configure a path with a "no" judgment result of the corresponding judgment node 6, and the corresponding expected result is "interactive message analysis error". As another example, if the public address configurations are different, the expected result is also a resolution error. The input variable public address is configured to configure a path with a "no" judgment result of the corresponding judgment node 10, and the corresponding expected result is also an "interactive message analysis error".

According to the above configuration input variables and the judgment results of the corresponding judgment nodes, the corresponding relationship between the configuration input variables and the expected results can be preset. Then, according to the preset corresponding relationship between the configuration input variables and the expected result, the expected result corresponding to each configuration input variable in the input variable combination and the judgment result in the path obtained in step S420 is obtained. And combining the expected results corresponding to each configuration input variable in the input variable combination to obtain the expected results of the input variable combination.

In another implementation, referring to fig. 2, content identification may also be performed on the nodes represented by the rectangles for each independent path in the processing flow diagram. From the contents of the nodes represented by the rectangles, the expected result corresponding to the branch can be extracted.

Referring to fig. 1 and 2, in step S150, the result of generating the device test case according to the input variable combination and the expected result is as follows:

device test case 1

Input variable combination: the server IP configuration is different from that of the opposite terminal instrument;

it is expected that: and the instrument at the opposite end is not connected to display, and the communication is abnormal.

Device test case 2

it is expected that: the opposite end instrument displays connection, and has interactive messages, but the analysis is wrong: the number of public address bytes is different.

Device test case 4

Input variable combination: the IP configuration, the port configuration and the byte number configuration of the public address of the server are the same, the public address configuration is different, and the point number configuration and the value type configuration are the same;

it is expected that: the opposite end instrument displays connection, and has interactive messages, but the analysis is wrong: the public addresses are different.

Device test case 5

Input variable combination: the IP configuration, the port configuration, the byte number configuration and the public address configuration of the server are the same, the point number configuration is different, and the value type configuration is the same;

it is expected that: and the opposite-end instrument displays connection, interactive messages exist, the messages are normally analyzed, and the point numbers are staggered.

Device test case 6

Input variable combination: the IP configuration, the port configuration, the byte number configuration, the public address configuration and the point number configuration of the service end are the same, and the value type configuration is different;

it is expected that: the opposite end instrument displays connection, interactive messages exist, the messages are analyzed normally, the point number change is correct, and the value types are not correct.

Device test case 7

Input variable combination: the IP configuration, the port configuration, the byte number configuration, the public address configuration, the point number configuration and the value type configuration of the service end are the same;

it is expected that: the opposite end instrument displays connection, interactive messages exist, the messages are analyzed normally, the point number change is correct, the value type is correct, and the communication is normal.

Among them, the device test cases 1 to 7 correspond to the paths 1 to 7, respectively. In the above configuration input variables, "common address word" refers to the content in bytes. For example, in an example of the "public address word" test, it may be tested whether the contents represented by the fifth and sixth bytes in the interactive message of the communication protocol are consistent. The data type of the interactive data of the network communication can comprise analog quantity, state quantity, accumulated quantity and the like. For the analog example, the value types may include floating point, integer, etc.
