Appium automated test scroll and drag_ and_ Drop slides according to element position

background

We are operating APP When applied , Some need to slide from one element to another , At this time, we cannot determine the coordinates , therefore swipe According to the coordinate sliding mode, it cannot be used , Here's the picture ： from Live class Slide up to Live open class Location

At this time, we need to use other sliding methods , We thought we could slide according to the elements ,Appium The main methods of sliding according to elements are scroll and drag_and_drop

scroll Introduce

explain

Scroll from one element to another , It can only be the sliding between two elements .

Method details

def scroll(self: T, origin_el: WebElement, destination_el: WebElement, duration: Optional[int] = None) -> T:
        """Scrolls from one element to another Args: origin_el: the element from which to being scrolling destination_el: the element to scroll to duration: a duration after pressing originalEl and move the element to destinationEl. Default is 600 ms for W3C spec. Zero for MJSONWP. Usage: driver.scroll(el1, el2) Returns: Union['WebDriver', 'ActionHelpers']: Self instance """

        # XCUITest x W3C spec has no duration by default in server side
        if self.w3c and duration is None:
            duration = 600

        action = TouchAction(self)
        if duration is None:
            action.press(origin_el).move_to(destination_el).release().perform()
        else:
            action.press(origin_el).wait(duration).move_to(destination_el).release().perform()
        return self

Parameters ：

• origin_el - Start element to scroll
• destination_el - End element to scroll to
• duration - The duration of the , Unit millisecond , The default is 600 ms

Operation scenario

• Enter Netease cloud homepage
• Slide from live classroom broadcast to live open class

Key code implementation

#  Locate the classroom live broadcast element 
el1 = driver.find_element(AppiumBy.XPATH, "//*[@text=' Live class ']").click()

#  Locate the live open class element 
el2 = driver.find_element(AppiumBy.XPATH, "//*[@text=' Live open class ']").click()

#  Of board ⾏ Sliding operation 
driver.scroll(el1,el2)

explain

• The operation process includes inertia , Need to add duration Parameters , The larger the parameter value is , The smaller the inertia .

drag_and_drop Introduce

explain

Slide from one element to another , The second element replaces the original screen position of the first element .

Method details

def drag_and_drop(self: T, origin_el: WebElement, destination_el: WebElement) -> T:
        """Drag the origin element to the destination element Args: origin_el: the element to drag destination_el: the element to drag to Returns: Union['WebDriver', 'ActionHelpers']: Self instance """
        action = TouchAction(self)
        action.long_press(origin_el).move_to(destination_el).release().perform()
        return self

Parameters ：

• origin_el - To slide the starting element of the page
• destination_el - To slide the page to the end element

Operation scenario

• Enter Netease cloud homepage

el2 = driver.find_element(AppiumBy.XPATH, "//*[@text=' Live open class ']").click()

#  Of board ⾏ Sliding operation 
driver.drag_and_drop(el1,el2)

explain

• Cannot set duration , No inertia

Slide and drag usage scene selection

Sliding and dragging are nothing more than considering whether it has “ inertia ”, And the parameters passed are “ Elements ” still “ coordinate ”.

• scroll： Yes “ inertia ” , Pass in “ Elements ”, Can be set by duration Parameters to control the inertia
• drag_and_drop： nothing “ inertia ” , Pass in “ Elements ”
• swipe： Yes “ inertia ” , Pass in “ coordinate ”, Can be set by duration Parameters to control the inertia

explain ： add to duration Parameters , The larger the parameter value is , The smaller the inertia
