Please refer to Fig. 1, it is the configuration diagram of the pressure test device in the present invention's specific embodiment.As shown in Figure 1, the transmitting-receiving of internet message bag is carried out between pressure test device 100 and game server 115 by transceiver module.Due to different game items, different procotols may be adopted, three kinds of dissimilar transceiver modules (transmitting-receiving Socket module 112, transmitting-receiving HTTP module 113, transmitting-receiving WebSocket module 114) are devised for the different game server project of adaptation in this embodiment, according to the procotol that game server 115 adopts, one of them Transmit-Receive Unit is in enabled state and carries out network service.Wherein,
Transmitting-receiving Socket unit 112 adopts the game server of the long connection mode of socket for adaptation, set up socket be connected with server, judges socket on connecting with or without message bag.
Transmitting-receiving HTTP unit 113 adopts http protocol to carry out the game server communicated for adaptation.Send http protocol network packet, structure HTTP packet header, read HTTP and return bag, judge HTTP return code.
Transmitting-receiving WebSocket unit 114 adopts the game server of WebSocket protocol communication for adaptation.This module comprises to be set up WebSocket with server and is connected, and reads bag mask and also resolves network packet, tectonic network bag, transmission packet and read the function of message bag.
Package module 111 on three transceiver modules.The server network bag that transceiver module is collected can be given package module 111 and carry out decapsulation, and the binary code stream from upper strata is given transceiver module and is sent to game server after package module 111 is packaged into network packet.Package module 111 for encapsulation network packet in, network packet add on identification number, length, the fields such as check bit, and when transceiver module get game server return come network packet after, from network packet resolve read these fields, obtain binary code stream.Because the mode of disparity items encapsulation network packet is different, package module 111 needs the functional unit for the adaptive corresponding encapsulation of detailed programs and decapsulation.
Is Encryption Decryption module 110 on package module 111.Major part project sends after all can be encrypted to network packet again, Encryption Decryption module 110 for being sent to package module 111 by from after the binary code stream encryption of byte parsing module 108, and is sent to byte parsing module 108 after being decrypted by the binary code stream from package module 111.Due to different projects, encrypting and decrypting mode is different, and Encryption Decryption module 110 needs for the adaptive corresponding encrypting and decrypting functional unit of detailed programs.
Be the byte parsing module 108 of project on Encryption Decryption module 110, data attribute value for the binary code stream from Encryption Decryption module 110 is reduced into concrete data attribute value, and is output into binary code stream by byte parsing module 108.The network packet of each type is a network packet class, each network packet class is needed to define this and is surrounded by which property value, all need to realize two function interfaces: a function interface is used for being obtained by bag property value the binary code stream of this bag, another function interface is used for the property value content arranging bag according to binary code stream simultaneously.Above-mentioned function interface can realize with the programming language irrelevant with server.Because function interface and project have nothing to do, this avoid the code module of dependent file, accomplish adaptive various project.
Because needs byte parsing module 108 pairs of binary code streams are resolved, for increasing work efficiency, in the present embodiment, analytical tool storehouse 109 is further comprises in this pressure test device 100, same layer is in byte parsing module 108, for providing the public method of various parsing binary code stream, so that byte parsing module 108 calls.It comprises following methods: by the shaping of different length, floating type, character type, and the statistical conversion of long shaping becomes binary code stream, and restores the method for above-mentioned Value Types by binary code stream, and the large end of definition stores or the method for small end storage networking byte.Network packet object attribute values is exported to binary code stream, and property value does not exceed shaping substantially, floating type, character type, the basic value types such as Boolean type, possesses very large general character between project.By analytical tool storehouse 109, the efficiency of the adaptive detailed programs of pressure test device 100 can be improved.
Because a lot of hand swims the network packet realization of project all based on the protobuf technology of Google at present, this technology provides unified network packet and the mutual conversion module of byte stream, project only needs the proto file providing its network packet to define.Because this embodiment adopts python language development, the python instrument that developer can adopt protobuf to provide, proto file is exported to the network packet module of python language definition, the reading of all-network bag and write function can be realized, thus realize byte parsing module 108.
Be action module 106 on byte parsing module, this module is used for each action of giving out a contract for a project of defining virtual user.Each network packet of pressure test device 100 is considered as a specific action, inside each action, defines the network packet object that this action will send, the network packet object that desired service device returns, and the input parameter that this action accepts.Action module 106 is by the parameter of input, and the property value of player role constructs the network packet object that will send to server.
Expect the network packet object that returns of game server owing to defining in action module 106, after virtual subscriber objects calls this action, if receive the network packet object of expectation, think this action successful execution, otherwise think that this action executing is unsuccessful.Can record simultaneously and give out a contract for a project and receive the time returning bag, as the response time of this bag; If there is the network packet that certain sends, do not return bag, can not specify in action module 106 and concrete return bag, when such robot calls this action, this action will not be recorded and whether run succeeded, and not recording responses time.The function of recording responses time is realized by response time logging modle 107.
Be task module 105 on action module 106, task module 105 defines the operation of Virtual User more complicated, and each task of task module 105 is made up of a series of actions, and adds Logic judgment process.To log in task, the task of logging in may comprise connection server, checking client version information, sends account, according to server rreturn value, judge, if new user, can new role be created, create role name, enter scene of game, if old user, old role can be chosen, enter scene of game.Task module 105 is exactly by this more complicated, and can be become task object one by one by the behavior that Virtual User often calls, and facilitates calling of the virtual subscriber objects on upper strata and functional test framework.
It is exactly virtual subscriber objects module 103 on task module 105, for arranging the task queue of virtual subscriber objects, the everything that all tasks of task module 105 comprise, constitute " behavior " of this virtual subscriber objects, virtual subscriber objects module 103 saves all properties of virtual players role simultaneously, such as grade, money, muscle power etc., these property values constitute " attribute " of this Virtual User.Such virtual subscriber objects, has possessed " attribute ", has also possessed " behavior ", and this virtual subscriber objects can isolated operation, tests for server capability; A large amount of virtual subscriber objects is called simultaneously, tests for server stress.
Functional test script module 102, it is the use case script used for On-board test, according to case script initialization of virtual user object, and connect with game server, game server also completes corresponding test assignment, obtain the data attribute value that server returns, whether the function carrying out validate service device is correct.Such as, time sometimes player gives a name to role, server can have length to limit to role name word, and character content is restricted, whether correct for testing this function, a test script can be write, allow Virtual User game server, create role and give a name to role, the message bag returned by server, judging that the whether serviced device of role's name receives, if create successfully, then delete this role, exit server, and run next use-case.By writing different test case, different name situations can be tested, avoids manual operations like this.
Unit testing frame module 101 is tested for function of organization.A complete test, needs to comprise test environment and prepares, test execution, test verification, test environment cleaning etc.Utilize the test frame that ripe, test script is organized, facilitate test script exploitation and run.
The virtual subscriber objects that scheduler module 104 depends on carries out pressure test to server, and it simulates a large amount of Virtual User, and game server carries out alternately, thus to server build-up of pressure.
Below in conjunction with Fig. 2, describe pressure test device 100 in detail and how to complete pressure test by scheduling Virtual User.Due to multithreading switching, to cause taking cpu performance too high, adopts association's journey technology in the present embodiment.Association's journey technology simulates multithreading by the method for software, is switch program block to perform in turn under single thread.Meanwhile, when occurring that IO blocks, being switched to other program blocks and performing, after IO blocks solution, then be switched to original program block execution.Pressure test device 100 is when a large amount of Virtual User of simulation, after the task of executing a Virtual User A, be switched to the task that another one Virtual User B performs its setting at once, Virtual User A needs the next task performed can be put into scheduling queue end, is performed after all executing before waiting list again.Meanwhile, if Virtual User immediately do not receive server return bag time, also can surrender right of execution, avoid performing obstruction.With single virtual user, the scheduler module 104 of pressure test device 100 can to distributing to the time period that its performs, and Virtual User needs a series of task that oneself performed or action, rationally takes apart and the system that is assigned to get on execution to its time period.
Meanwhile, generally a large amount of network packet of irregular transmission is to Virtual User for game server, and Virtual User needs to collect in time and responds these network packet, otherwise server can think that this user goes offline, and disconnects the connection with Virtual User.Such as, some game servers timing can send heartbeat packet to Virtual User, if Virtual User does not return a response packet, server can disconnect.Some game servers also need Virtual User regularly initiatively to send heartbeat packet to server, confirm that this user is online.
For solving the problem, method shown in the present embodiment Fig. 2 example: each Virtual User has a task queue 202, the task that this Virtual User of this queue record needs circulation to perform, comprises task 1, task 2, task 3, scheduler module 201 can according to the task list that Subscriber Queue stores, calling task successively, after task queue is complete, can from the beginning continue to call again, circulation be always gone down.After having dispatched a task of a Virtual User, the task of next Virtual User can be switched to and by that analogy, after all Virtual User have all dispatched a task, then switch back the next task of this Virtual User of scheduling.In the execution time section distributing to each Virtual User, Virtual User, except performing some tasks, also needs before executing the task, the message queue bag that processing server is sent, and sends heartbeat message bag to server.When some Virtual User do not receive the network packet expecting to return, Virtual User initiatively can surrender right of execution, is switched to next Virtual User, avoids the execution obstructing problem for wait network packet returns and cause.
As shown in Figure 2, processing messages queue, heartbeat packet sends and task 1 defines and needs in the scheduling time of Virtual User 1 work that performs in section.
Processing messages queue is used for collecting the message bag that between the last time period to current slot, server sends over, if server have sent heartbeat packet, then also needs return service device response packet.
Heartbeat packet transmission is used at the appointed time interval and sends heartbeat packet to server, and it can record the last time sending heartbeat packet, if current time interval has exceeded setting interval, will send heartbeat packet to server.
By above-mentioned design, avoid Virtual User answering server not in time, and solve under association's journey scheduling, the problem of timed sending heartbeat packet.
Below in conjunction with Fig. 3, explain how pressure test device 100 carries out the switching scheduling between Virtual User in detail.Pressure test device 100, except being switched to other Virtual User after the task of completing a Virtual User, is switched to other Virtual User when also can return bag at the server not receiving expectation.In some cases, game server can just return the network packet of response after a certain time to Virtual User, wait for this during in, in fact pressure test device 100 has been switched to other Virtual User and goes to have executed the task.
The principle realizing this mechanism is: the network of pressure test device 100 connects employing non-blocking fashion, when Virtual User performs specific tasks, after transmission packet to game server, check whether game server has network packet to return, if there is network packet to return, then all network packet returned are judged whether one by one be expect return bag, if not, then perform the process function of this bag correspondence; If so, then perform the process function of this expectation bag, and mark this tasks carrying success, after running succeeded, can right of execution be surrendered, allow robot dispatch the task of next Virtual User.If check that the network packet do not expected of server returns, this Virtual User can't wait always stay, but surrenders right of execution, when waiting for next time and be dispatched to this Virtual User, reexamines the expectation bag whether receiving server and return.If the time waited for exceedes certain time length, can mark this tasks carrying failure, this Virtual User can then perform next task.
Be illustrated in figure 3 scheduling flow when two Virtual User, first main thread dispatches Virtual User 1 (step 301), perform its queue task 1 (step 302), after tasks carrying completes, can switch back main thread (step 303), main thread then dispatches Virtual User 2 (step 304), performs its queue task 1 (step 305), after tasks carrying completes, switch back main thread (step 306), main thread then dispatches Virtual User 1 (step 307), the task 2 of executing the task in queue, now Virtual User 1 have sent message bag (step 308), and do not receive in time server return bag time, main thread (step 309) can be switched back, main thread scheduling Virtual User 2 (step 310) also performs its queue task 2 (step 311), after executing task 2, switch back main thread (step 312), and reschedule Virtual User 1 (step 313), what whether inquiry received that last task do not receive returns bag, after acknowledging receipt of and returning bag, the task 2 of Virtual User 1 just complete (step 314), switch back main thread again and dispatch Virtual User 2 (step 315-316), perform its queue task 3 (step 317).
This scheduling mode, avoid when Virtual User/association's journey do not collect in time server return bag time, cause to robot perform obstructing problem.
The application still another embodiment provides the embodiment solving the mutual pressure test scene of many people logic.As shown in Figure 4, adopt multiple Virtual User task queue, in queue, each member's content comprises: the task that concrete Virtual User and this user specifically will perform.Module 403 inside legend, namely 404,405 be the content stored inside queue, and scheduler module can the member of this queue of searching loop successively, dispatches concrete user to perform concrete task, has carried out many people interactive task.Such as, pressure surveys good friend's function, and need user A to add user B good friend, then user A removes the friend relation with user B again, just by this above-mentioned scene, can be designed to a task queue:
Task 1, user A initiates good friend's request,
Task 2, user B agrees to this request,
Task 3, the friend relation of user A releasing and user B.
Before each particular user task of execution, the message queue that this Virtual User needs processing server to send, and send heartbeat packet to server.
By many people task queue mechanism, solve the pressure test scene problem that many people logic is mutual.
Be to be understood that, although this instructions describes according to each embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
The foregoing is only the preferred embodiment of the application; not in order to limit the protection domain of the application; within all spirit in technical scheme and principle, any amendment made, equivalent replacements, improvement etc., all should be included within scope that the application protects.
