Embodiment
The display effect that the UI method of testing of embodiment of the present invention control is used for the UI of Confirmation Controls whether with matching desired by software development, whether the display effect of UI on different terminals that specifically can be understood as Confirmation Controls be identical, and whether the UI that namely this control is shown on different terminals there are differences.The similarity of mode to the UI shown by Target Photo and source picture that the method for testing of the embodiment of the present invention adopts color histogram and collection sudden change pixel to combine is tested, thus realizes the automatic Verification to UI, to test the display effect of UI.
The embodiment of the present invention can programming and testing software be stored in by this testing software and include but not limited to PC (PersonalComputer in advance, personal computer or computer) machine server (test equipment) in, automatically current process is monitored by this testing software, and next process of execution is triggered according to the programmed instruction preset after current process completes, realize the automatic test to UI.
In addition, the backup (image file) of the control (software) needed for test can be stored in the virtual machine of the cloud data center built in advance by the embodiment of the present invention in advance, the instruction sent according to the testing software programmed in advance in test process extracts the data needed for current short-range from the virtual machine of cloud data center, and test result is uploaded to this cloud data center.
Below in conjunction with method of testing embodiment illustrated in fig. 1, the technical scheme of exemplary embodiment provided by the present invention is clearly and completely described.As shown in Figure 1, the UI method of testing of the control of the present embodiment comprises following:
S11: image interception is carried out to obtain Target Photo to the UI of first terminal display, and image interception is carried out to obtain source picture to the UI of the second terminal demonstration.
S12: the color histogram calculating Target Photo and source picture, and the Pasteur's distance calculating the pixel value of Target Photo and source picture according to two color histograms.
Two color histogram correspondences represent the color characteristic of Target Photo and source picture, it describes different color ratio shared in view picture Target Photo and source picture, do not comprise the positional information residing for often kind of color, namely cannot describe the object in Target Photo and source picture or object.The mode calculating two color histograms can consult prior art, and the embodiment of the present invention is not limited.
Certainly, in order to improve computing velocity, the feature of the pixel negligible amounts that the embodiment of the present invention can comprise based on the Target Photo of institute's sectional drawing and source picture, by the such as R (Red of Target Photo and source picture, red) sub-pixel, G (Green, green) sub-pixel, B (Blue, blue) sub-pixel and W (White, white) total quantity of each colored sub-pixel is divided into predetermined equal portions (such as 16 parts) in sub-pixel, and equal portions of each colored sub-pixel are calculated to obtain Target Photo and color histogram corresponding to source picture.
The embodiment of the present invention can obtain described Pasteur's distance by following relational expression,

S13: when Pasteur's distance is greater than predetermined threshold, obtains position and first pixel value of multiple sudden change pixel on described Target Photo, and the second pixel value of the pixel of described position on the picture of source, and the pixel that wherein suddenlys change is the pixel on the profile of UI.
The span of predetermined threshold is for being greater than 0 and being less than 1.
Due to only can color distribution situation in evaluating objects picture and source picture by two color histograms, the position of each pixel in Target Photo and source picture can not be analyzed, therefore the catastrophe point (namely suddenly change pixel) of the further pixel value gathered in Target Photo of embodiment of the present invention needs is analyzed picture and is namely performed step S13 and S14, these sudden change pixels are that in Target Photo, zone boundary jumpy point occurs pixel value, the pixel on the profile of often UI.
Wherein, because the pixel value of the W sub-pixel of the UI of control is identical with the pixel value of the W sub-pixel in Target Photo, the pixel value thus only choosing R sub-pixel, G sub-pixel and B sub-pixel look occurs jumpyly to extract described sudden change pixel.
S14: the variance or the standard deviation that calculate the difference of multiple first pixel value and multiple second pixel value, and judge that when variance or standard deviation are zero the UI that control shows on first terminal and the UI shown in the second terminal matches.
The embodiment of the present invention can obtain described standard deviation by following relational expression,
Wherein, δ represents described standard deviation, z
irepresent the pixel value of the pixel of i-th a certain color,

On the basis of the above, the embodiment of the present invention can utilize the display interface of UiAutomator instrument to first terminal to resolve, and according to whether successfully resolved adopts corresponding mode to obtain Target Photo.Specifically: for the situation of successfully resolved, resolve the display interface of first terminal to obtain the coordinate information of UI on this display interface, carry out image interception to obtain Target Photo to the region corresponding with coordinate information on the display interface of first terminal further, the mouse data mouse beacon that wherein can be issued by testing software is selected the region corresponding with this coordinate information and is carried out image interception again.And for resolve unsuccessfully and without the need to the situation of the display interface (namely no matter whether successfully resolving the display interface of first terminal) of resolving first terminal, the embodiment of the present invention can manually operating mouse at the UI (icon) of the display interface upper ledge selected control of first terminal, thus to this display interface carried out image interception to obtain Target Photo by frame favored area.
Further, corresponding test code is generated according to the Target Photo obtained.Based on this, at the test phase of code playback, the mode that the embodiment of the present invention obtains source picture can be:
Obtain test code corresponding to Target Photo, and in validation test code, comprise the coordinate information of UI on the display interface of first terminal or relative position information.Wherein, the positional information of UI on the display interface of first terminal when coordinate information is display interface successfully resolved to first terminal; Relative position information is the positional information of the UI selected at the display interface upper ledge of first terminal by manual operation mouse when not resolving the display interface of first terminal.
If comprise coordinate information in test code, then image interception is carried out to obtain source picture to the region corresponding with coordinate information on the display interface of the second terminal.
If comprise relative position information in test code, then to the display interface of the second terminal carries out image interception to obtain source picture to the region corresponding with relative position information.
