Description of drawings
Fig. 1 has shown the process flow diagram of definite resource leakage method according to an embodiment of the invention.
Fig. 2 has shown the method for a kind of definite resource occupation according to an embodiment of the invention.
Embodiment
The use of the resource of the program of graphical interfaces and release conditions are comparatively complicated.Sometimes after operation, may increase also and may reduce taking of resource, also may operation once increase X quantity resource occupation, and same operation has caused Y quantity resource occupation next time. there is operating-system resources to distribute the effect of reclaim mechanism here, the effect of internal system contingency mechanism is also arranged, consequently from the operation of single, be difficult to judge the resource leakage situation of software, and then strengthened the difficulty that people understand the system resource leakage situation.
The present invention is based on following mode and eliminate the disturbing factor of above-mentioned judgement resource leakage respectively.
1) continued operation method
The method is used to eliminate the effect of resources allocation reclaim mechanism, this be because system the first time interface operation (interface operation is meant the interface between user and the software, the user is in order to the software issuing command, obtain result etc.) time application resource, and the resource that interface operation is afterwards applied for when just quoting interface operation for the first time usually, eliminate behind the resources allocation reclaim mechanism so the resource increased numbers that calculates behind the interface operation that repeats the continuous in theory second time is, be operating as on average but increase one-time continuous to be on the safe side again.
The method that the computational resource of the present invention's suggestion leaks: interim at a running software, the lasting rising that continuous three times (can expand to n time the positive integer of n＞=3) same interface operation all can produce the resource occupation number represents that promptly this operation produces resource leakage; This interface operation resource leakage amount be second and for the third time interface operation produce the mean value of resource leakage amount.
2) method of average
In addition, increase or reduce the influence that the resource leakage statistics is brought, can further use the method for average in order further to eliminate internal system contingency resource.
The concrete grammar of the method for average is: utilize n iteration of robotization playback tool cycle, for each iteration, by the continued operation method calculate respectively X1, X2 ..., the resource leakage number of Xn.Ask it
Average resource is leaked number=∑ (X1+X2+...+Xn)/n
With reference to the accompanying drawings 1, shown the process flow diagram of definite resource leakage method according to an embodiment of the invention.
But at first record the interface operation of playback, and produce playback script.Interface operation is meant the interface between user and the software, and the user obtains result etc. in order to the software issuing command.For example, one group of interface operation capable of circulation is to click certain button and close the dialog box that occurs subsequently.Add record specific resources (for example GDI) monitoring value function before each segment in playback script.
Playback script then, and produce the analytical table of monitored resource leakage.
At last, based on above-mentioned analytical table, utilize above-mentioned " continuity method " and/or " analytic approach " to analyze the resource leakage of described specific resources.
Below in conjunction with object lesson the present invention is described.
Example 1
Suppose that certain instant communication software need detect GDI resource leakage situation, this instant communication software has three operations commonly used, is respectively: " opening chat window ", " transmission chat message ", " change presence ".
Landing the original state that finishes is 314 GDI.
As shown in Figure 2, the resource occupation number of the GDI of software can be checked by the task manager of Windows operating system.
Calculate " opening chat window " GDI resource leakage:
Find that this moment, GDI was 365 after for the first time opening and close chat window, increment is 51 GDI, and then open same window and close the second time, this moment, GDI was 369, increment is 4 GDI, last open same window for the third time and close, this moment, GDI was 372, and increment is 3 GDI.(4+3)/and 2=3.5, so " opening chat window " on average can cause 3.5 GDI resource leakages.
Calculate " transmission chat message " GDI resource leakage:
Open chat window, sending chat message for three times, to observe the GDI sum respectively constant, and promptly the GDI resource leakage is 0.
Calculate " change presence " GDI resource leakage:
Close chat window, select to be different from other present state.Three observed GDI are respectively 375 (+3), 377 (+2), and 379 (+2), according to second for the third time the result: (2+2)/and 2=2, " change presence " produced 2 GDI resource leakages as can be known.
Record a script, in an iteration of script with the sequential operation of continued operation method: " opening chat window ", " transmission chat message ", " change presence " three operation is also calculated GDI one by one and is leaked number, iteration obtains following form 4 times:
Table 1
| The 1st iteration | The 2nd iteration | The 3rd iteration | The 4th iteration | |
| Open chat window | 3.5 | 4 | 4 | 4 |
| Send chat message | 0 | 0 | 0 | 0 |
| The change presence | 2 | 2 | 2.5 | 1.5 |
From this table as can be known:
On average " open chat window " GDI resource leakage number=∑ (3.5+4+4+4)/4=3.875～4.
On average " transmission chat message " GDI resource leakage number=∑ (0+0+0+0)/4=0.
On average " change presence " GDI resource leakage number=∑ (2+2+2.5+1.5)/4=2.
Attention will reflect the problem that tested program exists comparatively exactly in the application of reality, need a large amount of iterative datas, far not only 4 iteration, and these work just need automated test tool to control interface operation automatically and calculate automatically.
The invention provides the resource leakage amount that a kind of interface operation causes and determine method, it utilizes the stability of automatic playback instrument accurate assessment test interface program.Combining closely of this method and robotization playback instrument avoided a large amount of artificial interface operations, can save a large amount of valuable human resources; This method is accurately determined each caused by operations resource leakage amount, thereby provides foundation for assessment software stability accurately.This method can accurately be located the operation that causes resource leakage, thereby for fast and effeciently solving the resource leakage problem, strengthening the software product operation stability provides householder method.
