5. Explain each and every line. what it will do [4]?

6. In the same scenario[4] , how you read the data for 10 different test data?

7. How to get count of all the links in web page?

import org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; public class LinkCount { public static void main(String[] args) { System.setProperty(webdriver.chrome.driver,C:\\Users\\ghs6kor\\Desktop\\Java\\chromedriver.exe); WebDriver driver = new ChromeDriver(); String url = https://www.credosystemz.com/; driver.get(url); driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS); //Using tagname with anchor List<WebElement> links = driver.findElements(By.tagName(a)); System.out.println(“The number of links is “ + links.size()); driver.close(); }

8. How to read the data from Notepad?

package com.qa.practice; import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; public class ReadingNotepadData { public static void main(String[] args) throws IOException { String TestFile =C:\\Users\\ajain153\\Desktop\\testdata.txt; FileReader FR = new FileReader(TestFile); BufferedReader BR = new BufferedReader(FR); String Content = ; //Loop to read all lines one by one from file and print It. while((Content = BR.readLine())!= null){ System.out.println(Content); System.setProperty(webdriver.chrome.driver, C:\\Automation\\chromedriver_win32_2\\chromedriver.exe); WebDriver driver = new ChromeDriver(); driver.get(Content); String Tittle=driver.getTitle(); System.out.println(Tittle of Page is+ Tittle); } } }

9. How to read the file which is present in Network?[Like SharePoint]

10. Explain manual testing cycle from requirement?

Requirement Phase Testing also known as Requirement Analysis in which test team studies the requirements from a testing point of view to identify testable requirements and the QA team may interact with various stakeholders to understand requirements in detail.

Requirements could be either functional or non-functional. Automation feasibility for the testing project is also done in this stage.

11. Defect Life cycle.

Defect life cycle, also known as Bug Life cycle is the journey of a defect cycle, which a defect goes through during its lifetime. It varies from organization to organization and also from project to project as it is governed by the software testing process and also depends upon the tools used.

Need to Switch your career to automation:

12. How to instantiate Chrome driver?

System.setProperty(webdriver.chrome.driver,D:/your/path/to/Driver/chromedriver.exe); WebDriver driver = new ChromeDriver(); driver.manage().window().maximize(); driver.get(https://www.google.com);

13. Did you attend any Client calls from Onsite?

14. What is Maven, Git, Jenkins?

Maven:

It is the most important tool in the development, it provides developers a complete build lifecycle framework. It is used to check the compilation issues between framework components whenever multiple test engineer integrates their files into the same framework

Git is a Distributed Version Control System for tracking versions of files. Git allows you to track versions of your code in your local machine. However, if you want a remote backup of your code or want to publish your code to a community then you’ve to push it to Github

Jenkins:

Jenkins can be configured to email the content of the status of the build. Jenkins can be configured to distribute the build on multiple machines.

Project build: Jenkins documents the details of jar, version of jar and mapping of build and jar numbers.

Round 2:

15. Limitations of Selenium.

We cannot test mobile apps
Limited reporting
Handling dynamic Elements
Handling page load

16. Write a code for taking screenshot.

import org.apache.commons.io.FileUtils; import org.openqa.selenium.OutputType; import org.openqa.selenium.TakesScreenshot; import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; import java.io.File; import java.io.IOException; public class ScreenshotDemo { public static void main(String[] args) { //set the location of chrome browser System.setProperty(webdriver.chrome.driver, C:\\chromedriver.exe); // Initialize browser WebDriver driver = new ChromeDriver(); //navigate to url driver.get(https://demoqa.com); //Take the screenshot File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE); //Copy the file to a location and use try catch block to handle exception try { FileUtils.copyFile(screenshot, new File(C:\\projectScreenshots\\homePageScreenshot.png)); } catch (IOException e) { System.out.println(e.getMessage()); } //closing the webdriver driver.close(); } }

17. How to handle Alert?

Alert alt = driver.switchTo().alert(); // to move control to alert popup alt.accept(); // to click on ok. alt.dismiss(); // to click on cancel. //Then move the control back to main web page- driver.switchTo().window(mainPage); → to switch back to main page.

18. How to handle multiple windows?

import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; public class childWindow { public static void main(String[] args) throws InterruptedException { System.setProperty(webdriver.chrome.driver,./src/resources/chromedriver); WebDriver driver = new ChromeDriver(); driver.manage().window().maximize(); driver.get(https://demoqa.com/browser-windows); // Open new window by clicking the button driver.findElement(By.id(windowButton)).click(); // Click on the new window element and read the text displayed on the window WebElement text = driver.findElement(By.id(sampleHeading)); // Fetching the text using method and printing it System.out.println(Element found using text: ” + text.getText()); driver.quit(); } }

19. Annotations in TestNg.

20. Hierarchy of TestNg.

TestNG hierarchy package for classes. TestNg Annotations are,style =”color:white;”

@Beforesuite
@Aftersuite
@BeforeClass
@AfterClass

21. Difference between ‘Defect Retesting’ and ‘Regression Testing’.

Defect Retesting	Regression Testing
Involves testing a specific feature of the software.	Involves testing a general area of the software.
To ensure that the defects which were found and posted in the earlier build were fixed or not in the current build.	Repeated testing of an already tested program, after modification, to discover any defects introduced or uncovered as a result of the changes in the software being tested.

22. Do u know Database testing?

The Java Database Connectivity (JDBC) API provides universal data access from the Java programming language. Using the JDBC API, you can access virtually any data source, from relational databases to spreadsheets and flat files.
