Detailed Description
The application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be noted that, for convenience of description, only the portions related to the application are shown in the drawings.
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
The application provides a method, a device, equipment and a storage medium for realizing a network tool, which are used for describing an application, wherein the application refers to an application program adopting a C/S (Client-Server) architecture, and the C/S architecture is totally called a Client/Server (service end) architecture, and is a network architecture, wherein a Client is a personal computer device, a mobile terminal or a workstation and the like for running the application program by a user, and the Client is required to acquire resources by means of the Server. The C/S architecture reduces network traffic by providing query responses rather than total file transfers. Allowing multiple users to update to the shared database through GUI (graphical user interface ) front-ends, communication between clients and servers typically employs remote invocation (RPC) or Standard Query Language (SQL) statements.
At present, when an application is subjected to weak network test, application performance of the application in a weak network state is usually tested in a mode of random packet loss, and the application test can not be realized for each data packet, so that the test is incomplete, program errors and operation defects caused by discarding the same data packet are difficult to reproduce, and the problem positioning is difficult. In addition, the test mode is single, and the test requirement can not be well met.
Wherein weak network testing generally refers to: whether a problem occurs in the running process of the test application in a network environment with too high network delay and the like, and a weak network generally refers to network conditions such as poor network state, too high delay, network jitter, too high packet loss rate, limited bandwidth and the like.
Based on the above, the application provides a method, a device, equipment and a storage medium for realizing a network tool, which adopt test parameters matched according to the protocol type of any message to process the message in a targeted and different mode when the application is tested, thereby improving the comprehensiveness and reliability of the test, better meeting the test requirement of the application, and simply and conveniently realizing the positioning of the problem.
According to the implementation environment of the embodiment of the application, first messages between the client and the server of the application to be tested can be intercepted by personal computer equipment, a mobile terminal, a workstation and the like; determining a test parameter corresponding to the first message according to the protocol type of the first message and policy record information, wherein the policy record information comprises a plurality of protocol types and the test parameter corresponding to each protocol type in the plurality of protocol types; and processing the first message according to the test parameters, and determining the running state of the application after the first message is processed.
Alternatively, the method can be implemented by a server (i.e. a server side), for example: the personal computer equipment, the mobile terminal or the workstation sends a request to a server, and the server intercepts a first message between a client side and a server side of an application to be tested; determining a test parameter corresponding to the first message according to the protocol type of the first message and policy record information, wherein the policy record information comprises a plurality of protocol types and the test parameter corresponding to each protocol type in the plurality of protocol types; and processing the first message according to the test parameters, and determining the running state of the application after the first message is processed.
The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, a content distribution network (content delivery network, CDN), basic cloud computing services such as big data and an artificial intelligent platform.
The embodiment of the application provides a method for realizing a network tool, which can be applied to personal computer equipment, a mobile terminal or a workstation, and the like, namely: the network tool can be applied to personal computer equipment, mobile terminals or workstations and the like for network testing of applications. As shown in fig. 1, the method comprises the steps of:
101. And intercepting a first message between the client side and the server side of the application to be tested, wherein the first message is sent to the server side by the client side or sent to the client side by the server side.
In the running process of the application, the client side and the server side communicate with each other, namely: the first message is any one of the protocol messages, for example, a connection protocol message for establishing communication connection between the client and the server, or a data protocol message interacted when the client and the server realize various application functions.
Each message is interacted with by a protocol, and different messages may be transmitted between the client and the server using different protocols, for example: some messages are sent by clients to clients or clients by using the Request protocol and Response protocol, and some messages are sent by clients to clients or clients by using the Report protocol or the Notice protocol. Of course, the Request protocol and Response, report protocol or note described above are only examples, and other possible protocols may be used to send messages from the client to the server, or from the server to the client.
In a specific application, the function of intercepting the first message between the client and the server of the application to be tested can be integrated on the client, so that the client intercepts the message before the message arrives at the server each time when the client performs network interaction with the server, or intercepts the message transmitted by the server each time when the client does not arrive at the client.
In the above description, the application may be a variety of application programs employing a C/S architecture, for example: some online games, the client is a game client, the server is a game server, for example, a game jockey glows, the client is a jockey glows game client, the server is a jockey glows game server, the jockey glows game client can be installed on a personal smart phone, after the game client on the smart phone is started, a game playing function is realized on the smart phone through communication between the game client and the jockey glows game server.
102. And determining the test parameters corresponding to the first message according to the protocol type of the first message and the strategy record information, wherein the strategy record information comprises a plurality of protocol types and the test parameters corresponding to each protocol type in the plurality of protocol types.
As can be seen from 101, the message during communication between the client and the server may be implemented by a plurality of different protocols, so that the protocol types of the plurality of protocols used during the message transmission between the client and the server may be counted in advance. For example: the broadcast type message usually adopts Report protocol or Notice protocol, and the message needing to get Response can adopt Request protocol and Response protocol. Assuming that the various protocols used in the transfer of messages between the client and the server are counted to include 3 types, these 3 protocol types may be represented by specific symbols, for example: the 3 protocol types are denoted as 001, 002 and 003, and 001, 002 and 003 represent one of the 3 protocol types, respectively.
Setting a test parameter meeting test requirements for each protocol type, and then recording the test parameter set for each protocol type into strategy record information, namely: the policy record information includes a plurality of protocol types and test parameters corresponding to each of the plurality of protocol types. The policy record information may be any file capable of storing the test parameters, so that after the first message is intercepted, the protocol type of the first message is determined, and then the corresponding test parameters are matched from the file.
It should be noted that the test parameter may be a representation of the processing logic (i.e., the processing policy), for example: the 3 test parameters set for the 3 protocol types are A, B and C, respectively, the a corresponds to the protocol type 001, the B corresponds to the protocol type 002, and the C corresponds to the protocol type 003, and the a is a representation of a first processing logic, the B is a representation of a second processing logic, and the C is a representation of a third processing logic, where the first processing logic may be a processing logic of a packet loss operation, the second processing logic may be a processing logic of a delay operation, and the third processing logic may be a processing logic of a network disconnection operation. Assuming that the protocol type of the intercepted first message is 001, the test parameter which is queried to be matched with the first message in the policy record information is A, and the processing mode of the first message, namely processing logic, can be obtained through the A. Wherein the processing logic indicates what processing is performed on the first message, for example: packet loss processing, delay processing or discarding and simultaneously performing network disconnection processing.
Of course, the test parameter may be any preset identifier, where each identifier corresponds to a processing logic, for example: the policy record information is recorded with DB, YC and CN, the DB corresponds to the first processing logic, the YC corresponds to the second processing logic and the CN corresponds to the third processing logic.
103. And determining a processing strategy according to the test parameters, wherein different test parameters correspond to different processing strategies.
The correspondence between the test parameters and the processing policies may be recorded in a mapping table, for example: the mapping table includes two columns, each of the first column is a test parameter, and each of the second column is a processing policy, so that the first column and the second column of each row may be a correspondence, for example: the first row to the third row of the first column are the three test parameters A, B and C, respectively, and the first row to the third row of the second column are the processing policy one, the processing policy two and the processing policy three, respectively, then the mapping in this mapping table is concerned with: a and the first processing strategy are in a mapping relation, B and the second processing strategy are in a mapping relation, C and the third processing strategy are in a mapping relation, so that the first processing strategy can be determined by the A, the second processing strategy can be determined by the B, and the third processing strategy can be determined by the C. In a specific example, the first processing policy is, for example, a packet loss operation, the second processing policy is, for example, a delay operation, and the third processing policy is, for example, a network disconnection operation.
104. And processing the first message according to the processing strategy, and determining the running state of the application after the first message is processed.
In an embodiment of the present application, a processing policy for processing the first message includes, but is not limited to, a packet loss operation, a delay operation, and a network disconnection operation, and thus, processing the first message according to the processing policy includes: when the processing strategy is packet loss operation, carrying out packet loss processing on the first message; or when the processing strategy is to delay operation, forwarding the first message after the delay time; or when the processing strategy is the network disconnection operation, discarding the first message, and disconnecting the communication between the client and the server.
Taking the protocol type of the first message in 102 as 001 and the corresponding test parameter a as an example, firstly, obtaining a processing logic one (i.e. a processing policy one) from the test parameter a, wherein the processing logic one is a packet loss operation, assuming that the first message is sent by a client to a server, the first message is intercepted before the first message reaches the server, and then the first message is subjected to packet loss processing, namely: discarding the first message, that is, shielding the client from sending the first message to the server, where the server cannot receive the first message, and after the first message is processed in this way, since the application is running, the running state of the client of the application can be determined, that is: determining whether some abnormal conditions which are not allowed exist on the client side of the application, if so, indicating that the test of the application is not passed, and if so, indicating that the program code of the application has program errors or the application has running defects, otherwise, if some expected and well-set conditions exist on the client side, indicating that the test of the corresponding function of the application is passed, and not indicating that the corresponding program errors or running defects exist.
For example: for the game which the principals glory, the game client requests to open the knapsack and display the articles in the knapsack, at the moment, the game client sends corresponding information to the game server so that the game server feeds back the article information in the knapsack to the game client, under the scene, the information is intercepted and the network disconnection operation is carried out, after the network is waited for recovery, whether the knapsack is correctly opened and the articles in the knapsack are displayed in the game client is determined, if the knapsack is correctly opened and the articles in the knapsack are displayed in the network recovery, the knapsack is correctly opened and the articles in the knapsack are displayed in the correct operation state when the network is recovered, and if the articles in the knapsack are not correctly displayed after the network is disconnected and the network is waited for, the program code is indicated to have a program error or an application to have an operation defect, otherwise, the program code is indicated to have no program error or the operation defect.
Taking the protocol type of the first message in 102 as 002 and the corresponding test parameter B as an example, firstly, obtaining processing logic two (i.e. processing policy two) from the test parameter B, where the processing logic two is a delay operation, assuming that the first message is sent by the client to the server, before the first message reaches the server, the first message is intercepted, and then the first message is delayed and sent to the server, and the sequence of different messages received by the server may be out of order, after the first message is processed in this way, determining the running state of the client of the application, that is: determining whether some abnormal conditions which are not allowed exist on the client side of the application, if so, indicating that the test of the application is not passed, and if so, indicating that the program code of the application has program errors or the application has running defects, otherwise, if some expected and well-set conditions exist on the client side, indicating that the test of the corresponding function of the application is passed, and not indicating that the corresponding program errors or running defects exist.
For example: for the game which the principals glory, the game client requests to open the knapsack and display the articles in the knapsack, at the moment, the game client sends corresponding information to the game server so that the game server feeds back the article information in the knapsack to the game client, under the scene, the information is intercepted and delayed, if the information is forwarded after 10 seconds, whether the knapsack is correctly opened and the articles in the knapsack are displayed in the game client is determined, if the information is failed to be forwarded after 10 seconds, at the moment, the knapsack cannot be correctly opened and the articles in the knapsack are displayed, and the expected design is that the information can be forwarded and the knapsack can be smoothly opened and the articles in the knapsack are displayed after 10 seconds, so that the program code is determined to have a program error or an application operation defect, otherwise, the program code is determined to have no program error or operation defect.
In the above example, the delay operation is performed according to a delay time, for example: forwarding the first message after the delay time comprises: starting timing when the first message is intercepted; and when the timing time reaches the delay time, forwarding the first message according to the destination IP address and the port number, wherein the destination IP address and the port number are obtained by analyzing a message header of the first message.
Specifically, the test parameter B represents the second processing logic of the delay operation, and a default time parameter, i.e., delay time, may be configured in advance for the test parameter B, for example: and if the delay time is set to be 5 seconds, starting to count from the time of intercepting the first message sent from the client to the server, and forwarding the first message to the server after 5 seconds.
It should be noted that, the forwarding operation needs to know the destination, so before intercepting the first message and performing delayed sending, a header of the first message is obtained, where the header includes the destination IP address and the port number, so that the destination IP address (internet protocol address ) and the port number can be resolved from the header, and thus, the first message can be forwarded to the corresponding service end, that is, the destination according to the destination IP address and the port number.
Of course, the embodiment of the present application is not limited to obtaining the delay time according to the default time parameter, and may also generate the delay time according to a random number, for example: and configuring a random number for the test parameter B in advance, and then, after intercepting the first message sent by the client to the server, obtaining a random delay time according to the random number, so that the first message can be forwarded to the server after the random delay time. By delaying the random delay time to forward the first message, the running state of the application in the weak network state can be tested more truly, that is, in the real situation, when the network has problems, namely: weak net state, such as: in the case of poor network state, network jitter, etc., the delay time varies, so that the implementation of the network tool can be better realized through the random delay time.
It should be noted that, by generating the random delay time by the random number, in order to avoid the delay time being too long, the range of generating the random delay time may be determined to conform to the truly desired time range, for example, a time range of 2 seconds to 8 seconds.
Taking the protocol type of the first message in 102 as 003, the corresponding test parameter C as an example, firstly, obtaining processing logic three from the test parameter C, wherein the processing logic three is in a network disconnection operation, if the first message is sent to the server by the client, the first message is intercepted before reaching the server, then the first message is discarded, and in order to avoid interaction between the client and the server by other messages, the network disconnection operation is performed, in this case, whether the running state of the application meets expectations is determined, if the expectations are not met, the implementation of the network tool is not passed, and if the expectations are not met, the program code of the application has a program error or the application has a running defect, otherwise, if some expected and set conditions occur on the client, the test of the corresponding function of the application is passed, and the corresponding program error or running defect does not exist.
In a possible implementation manner, the communication between the client and the server is disconnected, including: executing a closing operation of the connection object to close the connection object, wherein the connection object is an object used for communicating with the server side in the client side; or performing a deletion operation of the connection object to delete the connection object. Assuming that the client and the server communicate through the Socket connection object, the Socket connection object is closed or deleted, namely: the Socket connection between the client and the server is actively cut off, so that the condition of network disconnection is simulated, the receiving and transmitting of other messages are shielded, and when the condition of real network interruption is simulated, whether the application exceeds the expected condition or not, namely: whether there is a program error or an operation defect.
When the network is disconnected, in general, the network reconnection will be performed between the client and the server of the application, and at this time, the client may send a second message to the server, that is: the second message is intercepted at the time of the reconnection request after the disconnection of the communication between the client and the server. In a possible implementation manner, after the communication between the client and the server is disconnected, the method further includes: discarding the second message when the second message is intercepted, wherein the second message comprises a reconnection request after communication between the client and the server is disconnected; and when the discarding times of the second message reach the preset times, releasing the intercepted second message again. That is, it can be tested whether an application can restore a network connection in case of a network outage. Assuming that network connection recovery is expected and it is tested that network connection recovery is not possible, a program error or an operation defect is indicated.
Specifically, because the situation of re-disconnection or repeated disconnection in the reconnection process of disconnection may occur in the real network, multiple interception and packet loss can be performed on the second message in the reconnection process to simulate the process of re-connection or repeated recovery of the network, and whether the application of the process correctly performs corresponding operation or not is tested.
In this example, in order to improve the test efficiency, the predetermined number of times need not be set to be too large, for example, set to 1 time, 2 times, 3 times or 4 times, so as to improve the implementation efficiency of the network tool and avoid the test in the reconnection process for a long time.
According to the implementation method of the network tool, after any message interacted between the client side of the application and the server side of the application is intercepted, the matched test parameters are selected from the strategy record information according to the protocol type of the message, and then the message is processed according to the matched test parameters, so that the messages of different protocol types are processed in a targeted and different manner, the processing behaviors of the message in real and different weak network states (such as network delay, over-high packet loss rate, network jitter and the like) can be simulated by the different processing manners, the implementation manner of the network tool has pertinence and diversification, and further, the application performance of the application in different weak network states can be better tested, and the implementation requirement of the network tool is well met. In addition, the implementation of the network tool can be carried out through each message, the comprehensiveness and the reliability of the test are ensured, and after the problem is found through the application test carried out by a certain message, the application test passing through the message can be reproduced, so that the problem can be conveniently and simply positioned. Namely: by intercepting the messages between the server and the client, different interception strategies are performed on messages of different protocol types, for example: the weak network conditions such as packet loss, delay, network disconnection and the like are simulated, and whether the functions applied during the weak network are normal can be well tested.
In one possible implementation, messages of a certain class or protocol type may be selectively intercepted and the running condition of the application tested. Thus, before intercepting the first message, further comprising: receiving a first input of an interception condition configuration item; and determining the message to be intercepted according to the first input. That is, providing a conditional configuration item in the client, by the selection above, i.e. the first input, it is possible to determine the message that needs to be intercepted. The functional implementation of the conditional profiles is integrated in the client, which is enabled by opening a command switch, on which there are a number of selectable items. The following is shown:
cmd instruction list:
disabling protocol transmissions
Disabling protocol reception
Adding all mask protocols
Restoring normal network state
Initiating hoisting link
Setting reconnection debugging times
ReqGetZonelist upstream packet loss
ReqGetZonelist downstream packet loss
NtyClientStatus loss
Selecting a forbidden protocol to send, wherein the forbidden protocol is used for carrying out packet loss on a message sent to a server by a client; selecting forbidden protocol reception, which means that the message sent to the client side by the server side is subjected to packet loss; adding all shielding protocols to represent interception of all messages; restoring the normal network state, wherein the state indicates that all messages are not intercepted; initiating reconnection, which means that the server and the client are reconnected through the network; setting reconnection debugging times to represent the times of starting reconnection; the ReqGetZonelist uplink packet is lost, which means that a specific message sent to a server side by a client side is lost; the ReqGetZonelist downlink packet is lost, which means that a specific message sent to a client by a server side is lost; the ntyclienstatus is lost, which means that a specific message sent by the server to the client and a specific message sent by the client to the server are lost.
From the selection in the Cmd instruction list described above, it may be determined that a message needs to be intercepted, for example: if the protocol transmission is forbidden, only the message sent by the client to the server is intercepted, and the message sent by the server to the client is not intercepted. Therefore, the required information can be intercepted, and the application can be subjected to targeted test, so that the test efficiency can be effectively improved.
In the case of a selected originating reconnection in the Cmd instruction list, in one possible implementation, a second input of an intercept condition configuration item may also be received; obtaining target interception times of the message according to the second input; and when the interception times of the message reach the target interception times, the message is released. The second input is to select the set reconnection debugging times, namely: by initiating reconnection and setting the selection of reconnection debugging times, the process of recovering network reconnection for the second time or multiple times can be simulated, and whether the process application correctly executes corresponding operation or not is tested. Therefore, the implementation of the network tool is realized more comprehensively, and the comprehensiveness and reliability of the test are improved.
In a possible implementation manner, the method for testing an application further includes: obtaining log information according to the intercepted first message, wherein the log information comprises a protocol type of the first message, interception time of the first message and an operation state of the application after the first message is processed; and writing the log information into a log file. For example: recording the intercepted information into a log file, so that the protocol coverage rate of the test can be obtained through the log file, and the error occurred in the operation of the application when the information is intercepted can be positioned. Therefore, the same test can be quickly reproduced, and the problem can be conveniently searched and positioned.
Taking a game application as an example, assuming that the game application is glowing to a king person, as shown in fig. 2, a process of logging in a main city in a game screen by a Client (i.e., a game Client) of the game application is shown, firstly, the game Client obtains a platform ticket from a third party platform GCloud, for example, obtains a platform ticket of an open platform (i.e., a game server) from a social platform (e.g., weChat), the open platform refers to a game server, obtains the platform ticket, then obtains a server list DirServer, and after obtaining the server list DirServer, for example, the server is glowing to a king person, the server list DirServer includes a Huadong server, a Huanan server, a Huabei server and a Huaxi server, and selects a connected server GameServer from the server list DirServer, for example, connects the Huadong server.
In this example, the message between the game server and the game client in the above process is not intercepted, and the reconnection test is not performed, namely: the reconnection mechanism is not walked, and detection of a network failure is typically manually retried by the player. In the process of acquiring the server list DirServer, the application itself is set with a timeout, namely: if the server list DirServer is not acquired after the timeout time, the application itself automatically retransmits the packet, namely: and re-acquiring the operation of the server list DirServer. In this example, the above process is not tested, and after the connection to the server game server is successful, the user logs in through the account, and after the account is successfully logged in, a character is selected, for example, a game character is selected, and after the game character is selected, a character login process is performed, that is: after the character is successfully selected, the character logs in the main city flow. In this example, in the account login process, corresponding messages are intercepted by the implementation method of the network tool, as shown in fig. 2, the message csreqplayerlegin is intercepted, the message type of the message csreqplayerlegin is determined to be 001, the query indicates that 001 corresponds to the test parameter a, and then the processing logic one is mapped out by the test parameter a, namely: the network disconnection operation is performed at this time, and after the network is disconnected for a certain period of time and the network is restored, whether a program error or an operation defect occurs can be judged according to the operation state of the application, for example: the method comprises the steps of determining whether an account successfully logs in, assuming that normal logic is that a game server clears a protocol buffer, successfully receiving a message CSReqPlayerLogin after network recovery, and rewriting the message CSReqPlayerLogin into the protocol buffer of the game server, so that the account can successfully log in, and therefore, whether an application has a program error or a running defect can be tested according to the action of whether the network recovery game server clears the protocol buffer. In addition, it is assumed that in the role registration flow, a message reqroleigin is intercepted and a disconnection operation is performed, so as to determine whether an operation such as automatic reconnection and packet sending is performed and whether disconnection detection is started according to an operation condition of an application, and if not, for example: if the character can not successfully log in, the test application has program errors or running defects, so that the error or running defects of the program code corresponding to the character logging in of the prince can be positioned, and the program code can be conveniently modified and debugged.
As shown in fig. 3, after intercepting the message csreqplayerlegin of the uplink packet sent to the server by the client and performing the network disconnection operation, whether the application has a problem can be tested according to whether the situation of deleting the confirmed packet in the buffer is executed after the latest packet sequence number received by the server, and similarly, after intercepting the message csreqplayerlegin of the downlink packet sent to the client by the server and performing the network disconnection operation, whether the application has a problem can be tested according to whether the situation of deleting the confirmed packet in the buffer is executed after the latest packet sequence number received by the client.
According to the implementation method of the network tool, after any message interacted between the client side of the application and the server side of the application is intercepted, the matched test parameters are selected from the strategy record information according to the protocol type of the message, and then the message is processed according to the matched test parameters, so that the messages of different protocol types are processed in a targeted and different manner, the processing behaviors of the messages in real and different weak network states (such as network delay, over-high packet loss rate, network jitter and the like) can be simulated by the different processing manners, the application test manner has pertinence and diversification, and further, the application performance of the application in different weak network states can be better tested, and the application test requirements are well met. In addition, the application test can be carried out through each message, the comprehensiveness and the reliability of the test are ensured, and after the application test is carried out through a certain message, the application test passing through the message can be reproduced, so that the problem can be conveniently and simply positioned.
Therefore, the application can test the application in a targeted manner through any message, and compared with the prior art, such as a mode of realizing the network tool according to the delay time and the packet loss rate, the application improves the comprehensiveness and the reliability of the test, better meets the realization requirement of the network tool, and can simply and conveniently realize the positioning of the problem.
