Specific embodiment
It should be appreciated that specific embodiment described herein is not intended to limit the present invention only to explain the present invention.
First embodiment：
In order to solve in prior art when testing to tested terminal, can be because test operating procedure be numerous
It is miscellaneous, and cause tester after tested terminal occurs exception, it is difficult to accurate reproduction causes tested terminal that exception occurs
The problem of test operation, the present embodiment provide a kind of terminal test method, and the method can be performed by terminal test device, please
With reference to Fig. 1：
S102, during testing to tested terminal, terminal test device is to tested terminal display interface
Display image cached.
As tested terminal is when tested personnel carry out operations, its display interface can be with operator
Operation and change, for example, when operator open video playback interface, the display interface of tested terminal will
The picture of current played video correspondence frame can be presented；Brightness of the tester to tested terminal plays video is adjusted
When, the brightness of tested terminal not only display picture can be improved, and can also in the display picture that may be in course of adjustment
Show the process that adjustment control changes；When tester browses webpage by tested terminal, tested terminal
Display interface will show corresponding webpage；If tester controls tested terminal from a page jump to other one
The individual page, then the page of tested terminal the page after redirecting can be not only presented, the display in jump procedure may also can be presented
Picture.As above example, under the operation of tester, its display picture can also be presented other changes to tested terminal
Change process.Although it is understood that the output of tested terminal is to the shape that the picture of its display screen is with image on a display screen
What formula was present, but these images are all exist with digital signal in tested terminal inner, and terminal test device is to tested
These digital signals of examination terminal are stored.The picture of storage is played back with certain speed after storage and can just be formed
Video.
Due to the special physiological structure of human eye, human eye in observing scene, the incoming cerebral nerve of optical signal, need through
One of short duration time, after the effect of light terminates, visual image does not disappear immediately, and the vision of this residual claims " after image ", depending on
This phenomenon felt then is referred to as " persistence of vision ".If in fact, when the frame per second of seen picture is higher than 16, will be recognized
For be it is coherent, therefore, although electronic equipment play video when, frame per second is to be not quite similar, nearly all electronic equipment
Frame per second when video is played is both greater than 20.For example, the frame per second of radio and television is 25 frames/s, and the frame per second of common mobile terminal
30 frames/s is mostly, or even the frame per second of part mobile terminal can reach 60 frames/s.Due to the effect of human vision effect, the mankind
The video that electronic equipment is played can just be seen.Also the frame per second just because of tested terminal may recognize non-coherent much larger than the mankind
The ability of picture, therefore, in the present embodiment, terminal test device, can be without when the display picture of tested terminal is cached
Store all pictures that tested terminal showed, but the picture shown from tested terminal according to certain sample frequency
It is middle to extract a part of picture and stored.For example, it is when tested terminal shows that the frame per second of video is 60 frames/s that is, tested
When will show 60 image frames in the terminal time per second, but terminal test device can with this 60 images at interval of one
Open picture selection one to be cached, even so, the image chosen out still there are 30, by this 30 pictures in the same second
Interior frame per second when playing out according to original sequencing still up to 30 frames/s, this is still able to shape for the mankind
Into coherent video.But after screening, terminal test device needs the picture of caching greatly reduce such that it is able to save
The memory space of storage display picture, reduces the requirement to terminal test device memory space.
Beyond all doubt, terminal test device is when tested terminal display is cached, it is also possible to without sieve
Select and be directed to whole display pictures and stored.Or when selecting extraction tested terminal display, can not
According to 1:The ratio of 2 (extracting one in i.e. two to be stored) is screened, it is also possible to according to 2:3 or 4:5 equal proportions are entered
OK, as long as 16 can be more than for the picture that each second extracts.
In the middle of above-mentioned example, when tested terminal is during being test for, terminal test device can cache quilt automatically
The display image of test terminal, this can detect the pattern residing for tested terminal, work as terminal mainly due to terminal test device
When test device detects tested terminal under tested pattern, terminal test device can automatically turn on tested terminal
Image buffer storage is enabled, to cache display image of the tested terminal in test process shown by display interface.
But as terminal test device is when the display picture of tested terminal is cached, it will make tested terminal system
Internal memory, CPU, GPU and power consumption are dramatically increased, and sometimes tester some simple tests are carried out to tested terminal,
Abnormal scene recovery video need not be generated the mistake for causing tested terminal that abnormal test operation occurs just can be repeated with oneself
Journey is how, therefore, in such a case, it is possible to enable without the image buffer storage for opening tested terminal.So, in the present embodiment
Another kind of example in the middle of, it is to issue cache instruction according to user by terminal test device that the image buffer storage of tested terminal is enabled
Open.That is, if carrying out caching to the display image of tested terminal can be determined by tester, relative to straight
For taking out the scheme that tested terminal image caching is enabled, this image buffer storage controlled by tester enables switch
Process may more meet the wish of tester, give tester and more select space.
In addition, tester can also send instructions to terminal test device, instruction terminal test device is closed tested
The image buffer storage of terminal is enabled, close the scheme that image buffer storage enables be applied to it is above-mentioned automatically turned on by terminal test device it is tested
Examination terminal image caching is enabled and tester passes through the image that cache instruction instruction terminal test device opens tested terminal
The scheme that caching is enabled.Enable tester that the image buffer storage of tested terminal is closed in some simple test processs
Enable, so as to reduce the occupancy to tested terminal system disposal ability and performance.
S104, after there is abnormal problem in tested terminal, terminal test device based on caching display image and go out
The time of existing abnormal problem generates scene recovery video.
After tested terminal occurs exception under the test operation of tester, tester needs multiple to research staff
What the test operation that stating causes terminal exception occur is successively, and more complicated for test operating procedure, tester can
Aid in determining the test behaviour before abnormal generation to generate scene recovery video by the terminal test device in the present embodiment
Make, scene recovery video can show the test operation before abnormal generation.
It should be noted that terminal test device generate scene recovery video be currently occur for tested terminal it is different
Often generate, therefore, the time that will be occurred based on tested terminal abnormal when generating scene recovery video is generated.Generally,
Tester voluntarily can generate the time by input video, including initial time and the time of termination of video, different in order to determine
The termination set of time for generating video typically the moment for abnormal by the reason for often occurring, tester can occur.And generate video
Initial time then decided in its sole discretion by tester's general layout practical situation.Therefore, in the middle of the other example of the present embodiment, user
The initial time for generating video can be only input into, by terminal test device using the abnormal time for occurring as the termination for generating video
Time.
The display image and the time for abnormal problem occur below to terminal test device based on caching generates field
The process of scape recovery video is simply introduced, and refers to Fig. 2：
S202, terminal test device receive the video generation instruction for generating the time occurred based on abnormal problem.
Video generates instruction is given birth to according to tested terminal abnormal problem time of occurrence by tester or research staff
Into, there is the abnormal time as tester may become more apparent upon tested terminal relative to research staff, and it is tested
When examination terminal occurs abnormal, tester should be in same position with which, and tested personnel can immediately according to instantly
Time generate scene recovery video, therefore, in the present embodiment, to terminal test device send video generate instruction it is basic
All it is tester.It is understood that tested terminal can also be recorded by tester occurs the abnormal time, work as research and development
When personnel are the reason for positioning tested terminal abnormal, scene recovery video is generated further according to the time of tester's record, because
This, video generates instruction and can also be issued by research staff.
S204, terminal test device parsing video are generated and instruct and obtain the initial time and termination time for generating video.
Based on introduction above, it will be understood that, in the present embodiment, video can include needing life in generating instruction
Into initial time and the time of termination of video, it is also possible to only including the initial time for generating video.So working as terminal test device
When being parsed only from video generation instruction a time, can give tacit consent to the time that tested terminal abnormal is occurred into the moment
As generate the time the termination time.If parsing two times, can using the preceding time in two times as
Generation is the initial time of video, using the posterior time as the termination time for generating video.
S206, terminal test device extract initial time and the display image stored between the termination time, and according to extraction
The display image for going out generates scene recovery video.
After terminal test device gets the initial time and termination time for generating video, it will aobvious from what is stored before
Initial time and the display image between the termination time are extracted in diagram picture, and it is multiple scene to be generated based on the display image for extracting
Former video.
The terminal test method provided in the present embodiment, by display interface is shown in test process to tested terminal
The display image shown is cached, and when tested terminal breaks down, can pass through the display image generation of caching
Scene recovery video recording tested terminal test operation for being experienced before it there is exception, generate scene recovery video it
Afterwards, what research staff can be just according to scene recovery video the reason for accurately understanding causes tested terminal to occur abnormal,
Do not need that tester is same as language or word is stated to research staff, it is to avoid tester subjective expression is inaccurate,
Mislead the problem of research staff；Simultaneously as eliminate research staff link up with tester the plenty of time for spending, therefore,
Terminal production efficiency can be lifted.
Second embodiment：
In order that those skilled in the art are it will be appreciated that the advantage and details of terminal test method, the present embodiment will be with reference to tool
The example of body is introduced to which.
In the present embodiment, the display image that terminal test device is preserved is the image in frame buffer (frame buffering)
Data.Terminal test device can pass through the value of cache frame buffer image enable (image frame buffer enable)
Image buffer storage to control tested terminal is enabled, as tested terminal system attribute cache frame buffer image
When the value of enable is 1, characterizes tested terminal and currently had been switched on image buffer storage function.As cache frame
When the value of buffer image enable is 0, the image buffer storage function of characterizing tested terminal is not currently activated.
The worth sizes of cache frame buffer image enable can be by terminal test device to tested terminal
Pattern detected that, when tested terminal is under the tested pattern, terminal test device can be cache frame
Buffer image enable are entered as " 1 ", and the image buffer storage for opening tested terminal is enabled, when tested terminal is in non-
Under test pattern, then terminal test device can be entered as " 0 " for cache frame buffer image enable, closed
The image buffer storage of tested terminal is enabled.In the middle of some other examples of the present embodiment, cache frame buffer
Image enable are worth size be input into by cache instruction by user, when user input cache instruction is to indicate to open quilt
During the image buffer storage function of test terminal, cache instruction of the terminal test device according to tester, by cache frame
The value of buffer image enable is revised as " 1 ", closes tested terminal when the cache instruction of tester's input is characterized
When image buffer storage is enabled, terminal test device is then by the cache frame buffer image enable values of tested terminal
It is revised as " 0 ".
It is opened when the image buffer storage of tested terminal is enabled, that is, cache frame buffer image
When the value of enable is 1, terminal test device can call create Cache Test Procedure () to create one
Individual test caching process.As shown in figure 3, in the present embodiment, test caching process 33 is based on linux kernel (Linux
Kernel) 32, and linux kernel 32 then needs the support of various hardware 31.It is various types of to be in top in whole framework
The application program 36 of type, exploitation and the operation of application program are all based on application framework 35, and application framework 35 passes through call function storehouse
Each function in 34 is realizing the various functions of application program 36.
This carry out central terminal test device can by interface save Frame Buffer Image () to show boundary
The display image in face is stored, the present embodiment an example work as this, terminal buffers device can with 640 × 480 point
Resolution preserves the view data in frame buffer.The cache path of display image can be such as：/mnt/sdcard/
Debug/framebuffer/ year-month-day-when-point-second-millisecond .jpg.Corresponding to the create for creating test caching process
Cache Test Procedure () interfaces, in the present embodiment, terminal test device may call upon release Cache
Test Procedure () interfaces test caching process to destroy, discharge.
Once tested terminal occurs exception in test process, terminal test device can be according to tester's input
Video generates instruction, calls input Start And End Time () interfaces, input that the initial time of video file is generated
With the time of termination, finally using output Video File () interfaces are according to the initial time of input and terminate the time, extraction
Display image in this time is generated video by the display image of caching, and in the middle of a kind of example of the present embodiment, terminal is surveyed
Trial assembly is put and can generate scene with AVC (H.264High Profile, 640 × 480 resolution, the frame per second of 30fps) coding and restore
Video, the scene recovery video file of generation can preserve to：/ mnt/sdcard/debug/test/ year-month-day-when-point
.mp4。
Simultaneously as the caching of display image expends memory space very much, therefore, when necessary, terminal test device
Need to empty the view data of caching, with release disk space.Terminal test device can be by calling clear Pre
Cached Images () is removing buffered data.The display image to having cached carry out deleting including mode
Including so several：
The first, in tested terminal closedown or when restarting, deletes the display image for caching before this.As north side is
Terminal closedown can characterize the current test of tested terminal when restart and have finished on, and exit test pattern
A kind of performance, therefore, it can all remove all display images for storing before at this moment.
Second, when the image buffer storage enabled state of tested terminal changes, namely cache frame buffer
When the value of image enable changes, can become from 0 in the value of cache frame buffer image enable
For 1 when, it is also possible to when its value is changed into 0 from 1, when the value of cache frame buffer image enable is from 0
When being changed into 1, sign will open the test for surveying a new round, and now, terminal test device can delete the institute for storing before
Some display images；And when the value of cache frame buffer image enable is changed into 0 from 1, characterize currently
Display image need not be stored, it is different from the test phase for storing display image before, therefore, it can delete before this
The display image of storage is vacateing memory space.
The third, deletes the display image that user specifies according to the image-erasing instruction that user issues.Delete aobvious by user
In the scheme of diagram picture, terminal test device can be monitored to the quantity of buffered display image, when discovery is delayed
When the display image deposited exceedes predetermined threshold value, terminal test device can issue the user with information, point out user to slow
The display image deposited is deleted, and then receive user is instructed according to the image-erasing that information is returned, and to image-erasing
Instruction is parsed, and determines the display image to be deleted that user specifies；The display image to be deleted determined is deleted finally.
Specify to terminal test device need to delete which display image when, user can refer in deletion according to the demand of oneself
Specified in order.But it is to be appreciated that terminal test device can preselect the display image number that part can be deleted
According to then in information, prompting user deletes the view data that this part is selected, when the deletion instruction catalogue that user returns is agreed
When determining, that is, characterize user and agree to delete this not sub-image data.It is this that the display image data that can be deleted is supplied to
User, can avoid user effort energy to screen needs the volume view data deleted, and gives user and preferably experiences.Terminal is surveyed
Trial assembly is put when issuing the user with information, can be carried out in the form of pop-up illustrated in fig. 4.
In the present embodiment, generation dynamic base can also be carried out for image buffer storage, so that tester is to hardware condition
When different various tested terminals is tested, the test can be called to cache process by terminal test device,
For the ease of it will be appreciated by those skilled in the art that in the present embodiment, there is provided a kind of scheme for generating dynamic base：

3rd embodiment：
The present embodiment provides a kind of terminal test device for performing terminal test method in first embodiment, refer to
Fig. 5：
Terminal test device 50 includes image buffer storage module 502 and video generation module 504.Tested terminal is being carried out
During test, image buffer storage module 502 is for caching to the display image of tested terminal display interface.To quilt
During test terminal is tested, video generation module 504 delays to the display image of tested terminal display interface
Deposit.
As tested terminal is when tested personnel carry out operations, its display interface can be with operator
Operation and change, for example, when operator open video playback interface, the display interface of tested terminal will
The picture of current played video correspondence frame can be presented；Brightness of the tester to tested terminal plays video is adjusted
When, the brightness of tested terminal not only display picture can be improved, and can also in the display picture that may be in course of adjustment
Show the process that adjustment control changes；When tester browses webpage by tested terminal, tested terminal
Display interface will show corresponding webpage；If tester controls tested terminal from a page jump to other one
The individual page, then the page of tested terminal the page after redirecting can be not only presented, the display in jump procedure may also can be presented
Picture.As above example, under the operation of tester, its display picture can also be presented other changes to tested terminal
Change process.Although it is understood that the output of tested terminal is to the shape that the picture of its display screen is with image on a display screen
What formula was present, but these images are all exist with digital signal in tested terminal inner, 502 pairs of quilts of image buffer storage module
These digital signals of test terminal are stored.After storage the picture of storage is played back with certain speed just can shape
Into video.
Due to the special physiological structure of human eye, human eye in observing scene, the incoming cerebral nerve of optical signal, need through
One of short duration time, after the effect of light terminates, visual image does not disappear immediately, and the vision of this residual claims " after image ", depending on
This phenomenon felt then is referred to as " persistence of vision ".If in fact, when the frame per second of seen picture is higher than 16, will be recognized
For be it is coherent, therefore, although electronic equipment play video when, frame per second is to be not quite similar, nearly all electronic equipment
Frame per second when video is played is both greater than 20.For example, the frame per second of radio and television is 25 frames/s, and the frame per second of common mobile terminal
30 frames/s is mostly, or even the frame per second of part mobile terminal can reach 60 frames/s.Due to the effect of human vision effect, the mankind
The video that electronic equipment is played can just be seen.Also the frame per second just because of tested terminal may recognize non-coherent much larger than the mankind
The ability of picture, therefore, in the present embodiment, image buffer storage module 502, can not when the display picture of tested terminal is cached
The all pictures shown with the tested terminal of storage, but the picture shown from tested terminal according to certain sample frequency
Extract a part of picture to be stored in face.For example, it is when tested terminal shows that the frame per second of video is 60 frames/s that is, tested
When examination terminal will show 60 image frames in the time per second, but image buffer storage module 502 can be with every in this 60 images
One, interval picture is chosen one and is cached, and even so, the image chosen out still has 30, and this 30 pictures are existed
Frame per second when playing out according to original sequencing in the same second still up to 30 frames/s, this for the mankind, or
Coherent video can be formed.But after screening, image buffer storage module 502 needs the picture of caching greatly reduce, from
And the memory space for storing display picture can be saved, reduce the requirement to 50 memory space of terminal test device.
Beyond all doubt, image buffer storage module 502 is when tested terminal display is cached, it is also possible to without
Screen and be directed to whole display pictures and stored.Or when selecting extraction tested terminal display, can be with
Not according to 1:The ratio of 2 (extracting one in i.e. two to be stored) is screened, it is also possible to according to 2:3 or 4:5 equal proportions
Carry out, as long as 16 can be more than for the picture that each second extracts.
In the middle of above-mentioned example, when tested terminal is during being test for, image buffer storage module 502 can be cached automatically
The display image of tested terminal, this can detect the pattern residing for tested terminal mainly due to terminal test device 50,
In the middle of another example of the present embodiment, as shown in fig. 6, terminal test device 50 also includes state adjusting module 506, work as shape
When state adjusting module 506 detects tested terminal under tested pattern, state adjusting module 506 can automatically turn on tested
The image buffer storage of examination terminal is enabled, to cache display image of the tested terminal in test process shown by display interface.
But as image buffer storage module 502 is when the display picture of tested terminal is cached, it will make tested terminal system
The internal memory of system, CPU, GPU and power consumption are dramatically increased, and tester is carrying out some simple surveys to tested terminal sometimes
Examination, it is not necessary to which generating abnormal scene recovery video and just being repeated with oneself causes tested terminal that abnormal test operation occurs
Process is how, therefore, in such a case, it is possible to enable without the image buffer storage for opening tested terminal.So, in this enforcement
In the middle of another kind of example of example, the image buffer storage of tested terminal enable be issued according to user by state adjusting module 506 it is slow
Deposit instruction unpack.That is, if carrying out caching to the display image of tested terminal can be determined by tester, phase
For the scheme that tested terminal image caching is enabled directly is opened, this image buffer storage controlled by tester is enabled
The process of switch may more meet the wish of tester, give tester and more select space.
In addition, tester can also send instructions to state adjusting module 506, instruction state adjusting module 506 is closed
The image buffer storage of tested terminal is enabled, close the scheme that image buffer storage enables be applied to it is above-mentioned by state adjusting module 506 from
Move the tested terminal image caching enable of unlatching and tester opens tested by cache instruction instruction state adjusting module 506
The scheme that the image buffer storage of examination terminal is enabled.Tester is enabled to close tested end in some simple test processs
The image buffer storage at end is enabled, so as to reduce the occupancy to tested terminal system disposal ability and performance.
After tested terminal occurs exception under the test operation of tester, tester needs multiple to research staff
What the test operation that stating causes terminal exception occur is successively, and more complicated for test operating procedure, tester can
Aid in determining the test before abnormal generation to generate scene recovery video by the video generation module 504 in the present embodiment
Operation, scene recovery video can show the test operation before abnormal generation.
It should be noted that the scene recovery video that video generation module 504 is generated currently is sent out for tested terminal
Raw abnormal generation, therefore, the time that will be occurred based on tested terminal abnormal when generating scene recovery video is generated.It is logical
Often, tester voluntarily can generate the time by input video, including initial time and the time of termination of video, in order to determine
The termination set of time for generating video typically the moment for abnormal by the reason for abnormal generation, tester can occur.And generate and regard
The initial time of frequency is then decided in its sole discretion by tester's general layout practical situation.Therefore, in the middle of the other example of the present embodiment, use
Family can only be input into the initial time for generating video, by video generation module 504 using the abnormal time for occurring as generation video
The termination time.
The display image and the time for abnormal problem occur below to video generation module 504 based on caching is generated
The process of scene recovery video is simply introduced：
First, video generation module 504 receives the video generation instruction of the time generation occurred based on abnormal problem.
Video generates instruction is given birth to according to tested terminal abnormal problem time of occurrence by tester or research staff
Into, there is the abnormal time as tester may become more apparent upon tested terminal relative to research staff, and it is tested
When examination terminal occurs abnormal, tester should be in same position with which, and tested personnel can immediately according to instantly
Time generate scene recovery video, therefore, in the present embodiment, to video generation module 504 send video generate instruction
It is substantially tester.It is understood that can also record tested terminal by tester there is the abnormal time, when
When research staff is the reason for positioning tested terminal abnormal, the time generation scene recovery further according to tester's record is regarded
Frequently, therefore, video generate instruction can also be issued by research staff.
Based on introduction above, it will be understood that, in the present embodiment, video can include needing life in generating instruction
Into initial time and the time of termination of video, it is also possible to only including the initial time for generating video.So working as video generation module
504 generate from video when only parse a time in instruction, can give tacit consent to and for tested terminal abnormal occur the moment
The termination time as the time of generation of time.If parsing two times, can be by the preceding time in two times
It is the initial time of video as generation, using the posterior time as the termination time for generating video.
After video generation module 504 gets the initial time and termination time for generating video, it will store from before
Display image in extract initial time and the display image between the termination time, and field is generated based on the display image for extracting
Scape recovery video.
The terminal test device provided in the present embodiment, by display interface is shown in test process to tested terminal
The display image shown is cached, and when tested terminal breaks down, can pass through the display image generation of caching
Scene recovery video recording tested terminal test operation for being experienced before it there is exception, generate scene recovery video it
Afterwards, what research staff can be just according to scene recovery video the reason for accurately understanding causes tested terminal to occur abnormal,
Do not need that tester is same as language or word is stated to research staff, it is to avoid tester subjective expression is inaccurate,
Mislead the problem of research staff；Simultaneously as eliminate research staff link up with tester the plenty of time for spending, therefore,
Terminal production efficiency can be lifted.
Fourth embodiment：
Continuing with reference to Fig. 5-Fig. 6, in the present embodiment, the display image that image buffer storage module 502 is preserved is frame
