Summary of the invention

The invention solves problems of the prior art, make full use of the characteristic of Android and flavor, according to the different operating positions record of complete operation in a different manner, and finish corresponding playback function according to the difference of recording mode, with the testing software behavior whether with revise before consistent.

For finishing the foregoing invention purpose, by the following technical solutions:

A kind of software operation recording and replaying method towards Android and flavor thereof comprises the steps:

1) equipment end of equipment Android and flavor thereof is connected with the PC end and communicates by letter;

2) equipment end is carried out the UI operation, equipment end or PC end record UI operational order and corresponding program state information;

3) the UI operational order and the corresponding program state information of record PC end analyzing step 2) utilize the UI operational order driving arrangement end of record to carry out the UI operation, and the corresponding program state of program state after will carrying out and record compares, and finish playback.

Equipment end and PC end is connected by the TCP/UDP/USB agreement and communicates by letter in the described step 1);

Equipment end is connected employing client end/server end pattern in the described step 1) with the PC end, and equipment end is a server end, and the PC end is client.

Described step 2) comprise following three steps:

2-1) the state of record server end starting point;

2-2) record UI operational order and corresponding program state;

2-3) the state of end of record (EOR) point;

Wherein, step 2-2) UI of equipment end operation has dual mode, and first kind is directly to operate in equipment end; Second kind is with communicating by letter of equipment end the current picture of equipment end to be presented at PC end virtual screen by the PC end, on PC end virtual screen, operate then, send the server program of equipment end to according to the corresponding operational order of virtual screen operative configuration, server program is carried out according to operational order driving arrangement end;

For first kind of mode, at server end new script file, the getevent instrument that utilizes Android system and flavor to provide obtains each bar instruction of operation and it is recorded in the server end particular script file, when the user inserts check point by client, server end inserts GUI information in the specific script file of server end, during end of record (EOR), server sends to client-side program with the script of equipment end;

For the second way, hold a newly-built script file (form of scripts meets basic format, can correctly resolve to get final product) at PC, in the instruction of PC end constructor and be recorded in the script file.PC end virtual screen and equipment end interface keep synchronously, interface information (status information such as UI object coordinate, the size etc. that comprise all crucial UI of interface of living in) after each equipment end operation is complete all sends to client-side program by server and redraws in client, and client-side program is inserted into GUI information in the script file.

The basic format of the script file in the above-mentioned steps is:

Instruction sequence;

Checkpoint；

Program state information;

Instruction sequence;

Checkpoint；

Program state information;

Status information during EOP (end of program);

For directly carrying out for the input mode of UI operation in equipment end, every order format in its instruction sequence as: shown in/dev/input/event0:0001 the 001e 00000001 ,/dev/input/event0 indication equipment; Back thirty senary number is presentation directives's type, key, key assignments respectively.

For for client (PC end) virtual screen input UI operation, every order format in its instruction sequence is:

EventType Action Eventdata, wherein EventType indication Action Events type (event type has KeyEvent, screen action event, time-event); Action indicates any operation (for KeyEvent Click and longclick operation to be arranged; For the screen action event click is arranged, operations such as drag and longclick; Operations such as wait are arranged for time-event), the operation that the Eventdata indication is concrete, which key what indication was pressed as KeyEvent is, and the coordinate that screen action event indication incident takes place etc.

After check point indication in the script file is carried out through a series of operational order, corresponding program state after need carrying out instruction checks the method for inspection is whether the program state after the program state information and instruction behind the check point is carried out in the comparison script is consistent;

Replayed section in the described step 3) comprises following three steps:

3-1) according to above-mentioned steps 2-1) in the recording setting playback time original state;

3-2) the script file that obtains according to the PC end, it is resolved corresponding operational order sequence and the corresponding program state information obtained, instruction sequence before each check point is sent to server, after server-side application executes the corresponding instruction sequence, be that the record that GUI sends to after the relevant detection point that writes down in client-side program and the script file compares with program state information;

3-3) the contrast playback finish the residing state in back whether with step 2-3) in the state consistency of record;

Step 3-2) tool is implemented as follows:

If what 3-2-1) record adopted is the mode of directly carrying out the UI operation in equipment end, then client (PC end) utilize the instrument sendevent tool configuration operational order that Android system and flavor provide according to the instruction sequence obtained and corresponding checkpoint information and send to server driving arrangement end carry out and whether check with expect consistent, if unanimity then continue to send the instruction of next bar, otherwise report an error; All instructions all send and finish in sequence;

If what 3-2-2) record adopted is the mode of operating at client (PC end) virtual screen input UI, then client sends to server one by one according to the operational order that writes down before, after server end drives a complete instruction, server sends to client-side program with server end interfacial state information, if be a Checkpoint this moment in the script, then client-side program relatively before the record status information, if it is consistent, then continue to send next bar instruction, otherwise report an error; If not Checkpoint, then continue to send next bar instruction.All instructions in sequence send and finish.

At step 3-3) in: carry out the mode of UI operation or adopt the mode of operating in equipment end no matter adopt directly at client (PC end) virtual screen input UI, after instruction sequence is finished, server will this moment status information of living in send to client-side program and with step 2-3) in the record state compare.

Compared with prior art, the technique effect that has of the present invention is:

Utilize method of the present invention that record is carried out in software operation on Android and the flavor platform, whether after software is made related amendments, it is preceding consistent with modification with the testing software behavior to utilize record to carry out playback.

Fig. 1 is the inventive method process flow diagram.

Embodiment

For clearer explanation the present invention, the spy is described as follows specific embodiments of the present invention:

This programme has been described the record replayed section under two kinds of modes of operation, and recording and playback system server terminal program is installed in equipment end, and client-side program is installed in the PC end.In recording process, server mainly is responsible for the operation of audiomonitor end and operational order and execution result is sent to client-side program, and client-side program mainly is responsible for reception execution command and corresponding results and it is put in order; And in replayed section, the instruction that client-side program mainly is responsible for writing down sends to server end in order, and server receives instruction rear drive equipment end and carries out corresponding instruction.The process of recording and playback mainly comprises: being connected of PC end and equipment end, start-of-record setting, recording operation instructs and corresponding program status information, end of record (EOR) setting, according to steps such as recording instruction sequence and the detections of correlation behavior information playback.Below in conjunction with accompanying drawing 1, each step is described respectively.

(1) the PC end is connected by USB interface with equipment end, the port that the PC that makes an appointment end is connected with equipment end can certainly use agreement such as TCP/UDP to connect connected mode employing client end/server end pattern, wherein the PC end is client, and equipment end is a server end; Both communications utilize java socket DLL (dynamic link library) to realize;

Initial state when (2) start-of-record being set, the information of record is kept at client with form of scripts, and initial state information is no exception.Status information when the user clicks client " opening entry " menu call client-side interface such as StartRecord () record server end initial, and the GUI information of server end sent to client and be presented on the virtual screen, its false code is as follows:

StartRecord_Client()

{

sendStartInfoToServer()；

waitForGUIInfo()；

loadGraph()；

recordGUIInfo()；

}

StartRecord_Server()

{

receiveStartInfoFromClient()；

DUMP()；

sendGUIInfoToClient()；

}

(3) equipment end is operated and record.Operation has a dual mode, and a kind of is that another kind is the enterprising line operate of the virtual screen in (2) in the equipment end operation, below describes the recording method of two kinds of modes of operation respectively.

(31) when using manual type, shown in the following false code of its operating process in the equipment end manual operations:

Record_Server(){

createFile(recordFile)；

recordInitialState(recordFile)；

while(){

if(isClient){

recordGUIInfo(recordFile)；

if(endRecord){

sendRecordFileToClient()；

exit；

}

setClient(false)；

}else{

recordInstrument(recordFile)；

}

Record_Client(){

If(checkpoint?or?endRecord){

setClient(true)；

if(endRecord){

sendEndInfoToServer()；

waitForServer()；

receiveRecordFile()；

}

As above shown in the code, at first create a script file, and opening entry at server end, when the user when client sends checkpoint or end record information, server end is inserted into program state information in the corresponding script file.

(32) when using the operation of client virtual screen, client and server end are carried out shown in the following false code of flow process:

Record_Client()

{

CreateFile (recordFile); //recordFile is a script file

If (endRecord) // if the end record sign

sendEndToServer()；

waitForServer()；

recordGUIInfo(recordFile)；

exit；

}

while(！endRecord){

MockInstrument () or insertCheckPoint (); // send and instruct or the checkpoint

If (IsOperation) // if instruction

RecordInstrument (recordFile); // recording instruction information

}

waitForServer()；

If // movable change or needs are DUMP information again

if(receive?activitychange?or?dumpInfo){

recordGUI?Info(recordFile)；

loadGraph()；

}

Else{

Continue；

}

Record_Server()

{

waitInformationFromClient()；

If // receive end of record (EOR) information, then GUI information is sent to client and release

if(receiveEnd) {

DUMP()；

sendDumpInfoToClient()；

exit；

}

// if the checkpoint then sends to GUI information client and release

if(isCheckPoiht){

DUMP()；

sendDumpInfoToClient()；

}

// if what receive is operational order, then implants instruction and execution

If // generation activity is switched, then derived information also will be herein as a checkpoint

if(receive?Instrument){

InjectEvent()；

if(activitychanged){

DUMP()；

sendDumpInfoToClient()；

}

else{

sendExeEndToClient()；

}

Client and server end interactive information, when the user clicks the insertion checkpoint menu of client or end record menu, server end will this moment equipment end GUI information derive and send to client by DUMP and upgrade virtual screen and preserve the state of this moment; When the user operates virtual screen, the instruction of client constructor is also held instruction, instruct to the server end transmit operation then, server end calls injectEvent () interface driving arrangement end and carries out, server end detects whether (user interface the interface takes place changes) switched in the generation activity, if do not have then directly send to finish to carry out message to client, next bar instruction of execution after the client reception message; If the generation activity is switched, then this is switched and be used as a checkpoint insertion processing automatically.

(4) when with manual mode operating equipment end, when the user clicks the end record menu of client, client utilizes interface such as sendEndToServer () to send ending message to server end, after server end is received message, the DUMP interface that calling system provides obtains current window GUI information and is inserted in the script file, and calling interface such as sendRecordFileToClient () send the script file of record to client, finishes then; When the user records by client virtual screen mode, when the user clicks the end record menu, server end receives behind the end calling interface such as sendDumpInfoToClient () and sends GUI information and withdraw to client, and client-side program is inserted into the information that receives in the script file.

(5) the script file form that is obtained by step (4) is (instruction 1, instruction 2, the checkpoint ..., done state information), manual mode and virtual screen mode of operation here order format are different, manual mode order format is as/dev/input/event0:0001 001e 00000001, wherein/dev/input/event0 refers to device name, back thirty senary number is represented type respectively, key and code value, concrete meaning has definition in the Android system; And the screen operator form is " EventType Action Eventdata ", wherein EventType indication Action Events type (event type has KeyEvent, screen action event, time-event); Action indicates any operation (for KeyEvent Click and longclick operation to be arranged; For the screen action event click is arranged, operations such as drag and longclick; Operations such as wait are arranged for time-event), the operation that the Eventdata indication is concrete, which key what indication was pressed as KeyEvent is, and the coordinate that screen action event indication incident takes place etc.Shown in the following false code of replayed section:

Replay_Client(recordSequence)

{

while(！recordSequence.end){

while(notCheckPoint){

sendInstrumentToServer()；

}

sendCheckPoint()；

waitForInfoFromServer()；

Whether // the information that relatively receives is consistent with the information of checkpoint

flg＝checkPointInfo(receive，checkpointInfo)；

If (flg==true) if // consistent, then continue

continue；

If else{ // inconsistent then reports an error and returns

ReportError()；

exit；

}

Replay_Server()

When the manual mode playback, must earlier the sexadecimal number in the instruction be converted to decimal number, and structure instruction as " sendevent/dev/input/event0:1,30,1 ".
