Mobile phone Automation test: Appium Source analysis of Bootstrap five

Poptest is the only training institute for developing Test and development engineers in China, aiming at the ability of the trainees to be competent in automated testing, performance testing and testing tools development. Poptest Test Development Engineer Employment Training please consult qq:908821478) Mobile automation testing is the technical requirements of future Test engineers, we need to lay a good foundation.

Absendpos.y.intvalue (), steps);

First analyze the source code:

Final hashtable<string, object> params = Command.params ();
Final point start = new Point (Params.get ("StartX"), Params.get ("Starty"));
Final point end = new Point (Params.get ("EndX"), Params.get ("EndY"));
Final Integer steps = (integer) params.get ("Steps");
Final Uidevice device = Uidevice.getinstance ();

Point absstartpos = new Point ();
Point absendpos = new Point ();

First get the parameters from the command, and then parse out 3 variables: Start point start, endpoint end, step steps. Then get the device object and define 2 private point objects for later use.
It is then conditionally processed to handle the control or handle the coordinates.

Control:

Final androidelement el = command.getelement ();
Absstartpos = El.getabsoluteposition (start);
Absendpos = El.getabsoluteposition (end, false);

First get the control object, and then pass the different parameters through GetAbsolutePosition to get the start point and end point of the click on the control.

Public Point GetAbsolutePosition (final point,

Final Boolean boundschecking) throws Uiobjectnotfoundexception,

invalidcoordinatesexception {

Final rect rect = El.getbounds ();

Final point pos = new Point ();

Logger.debug ("Element bounds:" + rect.toshortstring ());

if (Point.x = = 0) {

Pos.x = Rect.width () * 0.5 + rect.left;

} else if (point.x <= 1) {

Pos.x = Rect.width () * point.x + rect.left;

} else {

Pos.x = Rect.left + point.x;

}

if (boundschecking) {

if (pos.x > Rect.right | | pos.x < rect.left) {

throw new Invalidcoordinatesexception ("X Coordinate ("

+ pos.x.tostring () + "is outside of element rect:"

+ rect.toshortstring ());

}

}

if (Point.y = = 0) {

Pos.y = Rect.height () * 0.5 + rect.top;

} else if (Point.y <= 1) {

Pos.y = Rect.height () * point.y + rect.top;

} else {

Pos.y = Rect.left + point.y;

}

if (boundschecking) {

if (Pos.y > Rect.bottom | | pos.y < rect.top) {

throw new Invalidcoordinatesexception ("Y Coordinate ("

+ pos.y.tostring () + "is outside of element rect:"

+ rect.toshortstring ());

}

}

return POS;

}

The above code first parses the x-coordinate and then parses the y-coordinate. The x and Y coordinates are judged and processed the same

First determine if the X coordinate is 0, and if 0, the X coordinate of the initial point is the horizontal axis of the control's center point. If the coordinates of x are less than 1, the coordinates are relative coordinates, and the values are evaluated by the percentages, and then the product operation with the width is given a specific value. If the above 2 cases do not meet, that is the specific coordinate value, then the direct element of the x-coordinate value plus the border of the control left coordinate value.
Finally, based on the Boolean value passed in to determine whether to do an out-of-bounds validation. If the boundary is exceeded, the exception is run. The y-coordinate is obtained in a similar way. Finally, we get the coordinate value and return it to the Execute method.

Coordinate

Absstartpos = Getdeviceabspos (start);
Absendpos = Getdeviceabspos (end);

Initializes a previously declared private point object by calling the Getdeviceabspos () method to get the coordinate value.

Protected static point Getdeviceabspos (final point point)

Throws Invalidcoordinatesexception {

Final Uidevice D = uidevice.getinstance ();

Final point retpos = new Point; Copy inputed Point

Final Double width = (double) d.getdisplaywidth ();

if (Point.x < 1) {

retpos.x = width * point.x;

}

if (retpos.x > Width | | retpos.x < 0) {

throw new Invalidcoordinatesexception ("X Coordinate ("

+ retpos.x.tostring () + "is outside for screen width:"

+ width.tostring ());

}

Final Double height = (double) d.getdisplayheight ();

if (Point.y < 1) {

Retpos.y = height * POINT.Y;

}

if (Retpos.y > Height | | retpos.y < 0) {

throw new Invalidcoordinatesexception ("Y Coordinate ("

+ retpos.y.tostring () + "is outside of the screen height:"

+ height.tostring ());

}

return retpos;

}

Similar to the above method, it is also to determine whether the transferred coordinate value is less than 1, if less than 1, as a percentage of the ball coordinate value. If an exception is thrown beyond the range of the screen, the last coordinate value is returned back to the Execute method.

Final Boolean RV = Device.swipe (Absstartpos.x.intvalue (),
Absstartpos.y.intvalue (), Absendpos.x.intvalue (),
Absendpos.y.intvalue (), steps);

Finally, call the Uidevice.swipe method to execute the command to determine whether the execution was successful.

Summarize
The Execute swipe command has 2 command format
A. Controls
B. coordinates
The coordinate is divided into the relative coordinate percentage and the absolute coordinates two kinds of methods.
