For Android: Have total 9 W3C Mobile Gestures Commands

mobile: clickGesture

mobile: doubleClickGesture

mobile: longClickGesture

mobile: pinchCloseGesture

mobile: pinchOpenGesture

mobile: swipeGesture

mobile: scrollGesture

mobile: dragGesture

mobile: flingGesture

Complete Details on “mobile: scrollGesture” Command:

mobile: scrollGesture — performs scroll gesture on the given element/area.

Supported arguments

elementId: The id of the element to be scrolled. If the element id is missing then scroll bounding area must be provided. If both the element id and the scroll bounding area are provided then this area is effectively ignored.

left: The left coordinate of the scroll bounding area

top: The top coordinate of the scroll bounding area

width: The width of the scroll bounding area

height: The height of the scroll bounding area

direction: Scrolling direction. Mandatory value. Acceptable values are: up, down, left and right (case insensitive)

percent: The size of the scroll as a percentage of the scrolling area size. Valid values must be float numbers greater than zero, where 1.0 is 100%. Mandatory value.

speed: The speed at which to perform this gesture in pixels per second. The value must not be negative. The default value is 5000 * displayDensity

Returned value

The returned value is a boolean one and equals to true if the object can still scroll in the given direction

Usage examples: // Java

boolean canScrollMore = (Boolean) ((JavascriptExecutor) driver).executeScript(“mobile: scrollGesture”, ImmutableMap.of(

“left”, 100, “top”, 100, “width”, 200, “height”, 200,

“direction”, “down”,

“percent”, 1.0

));

Sample Code:

WebElement element=driver.findElement(AppiumBy.androidUIAutomator(“new UiSelector().className(\”android.widget.ScrollView\”)”));

((JavascriptExecutor)driver).executeScript(“mobile: scrollGesture”,ImmutableMap.of(

“elementId”,((RemoteWebElement)element).getId(),

“direction”,”down”,

“percent”,0.88)); //75% = 0.75,50% = 0.5,100%= 1.0
