Referring to Fig. 1, Fig. 1 is a kind of test method flow chart of page presentation speed of the embodiment of the present invention, including as followsStep:
Step 101, at the time of by the invocation target page, it is determined as page presentation start time.
In a kind of implementation, the method that system is shown by invoking page carrys out displayed page.Acquisition system invocation targetCurrent system moment TB when the page, that is, at the time of the invocation target page, and TB is saved and is used as target in memoryPage presentation start time.
In embodiments of the present invention, target pages can be the application program page in terminal.Such as: target pages can be withFor the homepage of the photograph album in terminal.
Step 102, since page presentation start time, a screen interception operation is executed at interval of preset duration, is obtainedObtain preset quantity screenshot and the screenshot corresponding interception moment.
Specifically, can star the timer that timing length is preset duration t；When reaching timer timing length,A screen interception operation is executed, the screenshot and the corresponding interception time of the screenshot of current display page are obtained；Then judgeWhether the quantity of the screenshot obtained is equal to preset quantity n, if it is, stopping executing screen interception operation；If it is not, thenReturn to the step of starting timing length is the timer of preset duration t.
In this hair embodiment, in order to guarantee corresponding section of finish time in the screenshot got comprising page presentationFigure, the time for executing screen interception operation need to be greater than maximum duration consumed by default displayed page.So needing to be arranged, in advanceIf the product of duration and preset quantity is greater than maximum duration consumed by default displayed page.
For example, maximum duration consumed by default displayed page can be 500 milliseconds, then preset duration t can be setIt is 10 milliseconds, n is set as 100, the product of such t and n are greater than maximum duration consumed by default displayed page.
In embodiments of the present invention, time interval t can be reduced under the premise of the product of t and n is constant, so that obtainingThe target screenshot corresponding interception moment closer to page presentation finish time, allow to obtain page presentation speed more accurate.
In embodiments of the present invention, a screen interception operation can have been executed with every, has recorded the current screen interception that executes and graspsThe number w of work continues to execute screen interception operation if w < n；If w=n, stop timing device.
