Top API Interview Question 1-10
Lets us learn how to take screenshot for the specific element, following method i'm using to get screenshot, infact we can use this as a uitility class also and reuse it in the BaseTest Class.
public static String takeScreenshot(AppiumDriver<MobileElement> driver, MobileElement ele)
{
File screenshotLocation = null;
try{
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
BufferedImage fullImg = ImageIO.read(scrFile);
//Get the location of the element on the page
Point point = ele.getLocation();
//Get width and height of the element
int eleWidth = ele.getSize().getWidth();
int eleHeight = ele.getSize().getHeight();
//Crop the entire page screenshot to get only element screenshot
BufferedImage eleScreenshot= fullImg.getSubimage(point.getX(), point.getY(), eleWidth,
eleHeight);
ImageIO.write(eleScreenshot, "png", scrFile);
String path = "screenshots/" + UUID.randomUUID() + "" + ".png";
screenshotLocation = new File(System.getProperty("user.dir") + "/" + path);
FileUtils.copyFile(scrFile, screenshotLocation);
System.out.println(screenshotLocation.toString());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return screenshotLocation.toString();
} |

There is one more scenario where we need to take screenshot of a specific element in Appium, for that I have written a post describing the usage and steps: refer to the post below:
TAKE SCREENSHOT OF SPECIFIC ELEMENT IN APPIUM
**************
REVISION:==>
==>. How we can verify the Appium installation, what is Appium doctor?
Ans: To verify that all of Appium's dependencies are met we can use appium-doctor.
Install it with commandnpm install -g appium-doctor, then run the appium-doctor command, supplying the --ios or --android flags to verify that all of the dependencies are set up correctly.
==>. What is the default port for Appium?
Ans: 4723
This port information is important since we will have to direct your test client to make sure to connect to Appium on this port. If we want to change, the port, we can do so by using the -p flag when starting Appium.
==> What are the important Appium Desired Capabilities?
Ans:
{
"platformName": "iOS",
"platformVersion": "11.0",
"deviceName": "iPhone 11",
"automationName": "XCUITest",
"app": "/path to app"
}
==> Mention the Automation engine for android and IOS?
Ans:
Android: UiAutomator2
IOS : XCUITest
