Introduction to Appium

Appium is an open-source framework for automating native, mobile web, and hybrid applications on Android mobile, iOS mobile, and Windows desktop platforms. For starters, Appium was developed by Dan Cuellar and Jason Huggins and today has about 15.2K stars and 5.7K Fork on GitHub. It has the highest market share compared to all the other mobile automation frameworks.


Installation of Appium via Desktop App

Simply download the latest version of Appium Desktop from the releases page of Appium official website.

Appium Desktop



Start Appium Server

  1. we can start by clicking on the ‘Start Server’ button inside of Appium Desktop as shown below.

    2. ‘Start Server’



One of the hidden features that Appium has is screen recording. It is inbuilt and unlike configuring things externally like how we do with Selenium, the APIs are available out of the box.

Step-1: Add the Class VideoRecordUtils in Util package


Package com.appium.utils;

import java.io.File;
 import java.io.FileNotFoundException;
 import java.io.FileOutputStream;
 import java.io.IOException;
 import java.util.Map;

import org.apache.commons.codec.binary.Base64;
 import org.testng.ITestResult;

import static com.appium.constants.FrameworkConstants.YES;
 import com.appium.manager.DateTimeManager;
 import com.appium.manager.DriverManager;

import io.appium.java_client.screenrecording.CanRecordScreen;

public class VideoRecordUtils {
//To record the screen, we need to call the startRecordingScreen() method from the respective class.

 public static void startRecording() {

if (ConfigLoader.getInstance().getFailedTestsVideo().equalsIgnoreCase(YES)) {
((CanRecordScreen) DriverManager.getDriver()).startRecordingScreen();
 }
 }
// In order to stop the recording, we need to call the stopRecordingScreen() method from the respective classes.

 public static void stopRecording(ITestResult result) {

 if (ConfigLoader.getInstance().getFailedTestsVideo().equalsIgnoreCase(YES)) {
 /* Do only when Test is failed */

 if (result.getStatus() == 2) {

 String media = ((CanRecordScreen) DriverManager.getDriver()).stopRecordingScreen();

Map<String, String> params = result.getTestContext().getCurrentXmlTest().getAllParameters();

 String dir = "Videos" + File.separator + File.separator + params.get("platformName") + "_"
 + params.get("deviceName") + "_" + params.get("udid") + File.separator
 + DateTimeManager.getDateTime() + File.separator
 + result.getTestClass().getRealClass().getSimpleName();

createFolderCopyFile(result, media, dir);
 }
 }
 }

private static void createFolderCopyFile(ITestResult result, String media, String dir) {
 File videoDir = new File(dir);
 if (!videoDir.exists()) {
 videoDir.mkdirs();
 }
 FileOutputStream stream = null;

 try {
 stream = new FileOutputStream(videoDir + File.separator + result.getName() + ".mp4");
 } catch (FileNotFoundException e1) {
 e1.printStackTrace();
 }

 try {
 stream.write(Base64.decodeBase64(media));
 } catch (IOException e) {
 e.printStackTrace();
 }
 }
 }

STEP-2: Call the StartRecording and StopRecording Methods


Then we need to update BeforeMethod and AfterMethod to start and stop the recording, in the BaseTest, this class is supposed to be extends in your test classes, here we will call the method created in step-1

      @BeforeMethod
 public void beforeMethod() {
 VideoRecordUtils.startRecording();
 }
@AfterMethod
 public void afterMethod(ITestResult result) {
 VideoRecordUtils.stopRecording(result);
 }




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
