9. How can we launch different browsers in the selenium web driver?

•  By creating an instance of the driver of a particular browser

 WebDriver driver = new ChromeDriver();

10.What is the use of driver.get("url") and driver.navigate().to("url")command?

•  Both driver. get("url") and driver.navigate().to("URL") commands are used to navigate to a URL passed as a parameter.

11. How can we type text in a textbox element using selenium?

•  using the sendKeys() method we can type text in a textbox.

JavaScriptExecutor in Selenium WebDriver

 JavaScript:

•  JavaScript is a programming language that interacts with HTML DOM within the browser.

JavaScriptExecutor:

•  JavaScript executor is an interface provided by Selenium that gives a mechanism to execute JavaScript through Selenium WebDriver.
•  It provides two methods such as “executeScript” & “executeAsyncScript” to run JavaScript on the currently selected frame, window, or page.

Uses of JavaScriptExecutor:

•  There are locators in Selenium WebDriver like ID, Class, XPath, etc., to work with elements on a web page.
•  Sometimes these default Selenium locators may not work.
•  JavaScriptExecutor is used to perform operations on a web page.
•  JavascriptExecutor in Selenium enables the WebDriver to interact with HTML DOM within the browser.

1. Type Text in a Text Box

 JavascriptExecutor js = (JavascriptExecutor) driver;

 js.executeScript("document.getElementById('Email').value='suriya@gmail.com';");

2. To Click on a Button

 js.executeScript("document.getElementById('enter your element id').click();");

3. To refresh browser window using Javascript

 js.executeScript("history.go(0)");

4. To get the inner text of the entire webpage in Selenium

 String Text =  js.executeScript("return document.documentElement.innerText;").toString();

 System.out.println(Text);

5. To get the Title of our webpage

 String Text =  js.executeScript("return document.title;").toString();

 System.out.println(Text);

6. To get the URL of a webpage

 String Text =  js.executeScript("return document.URL;").toString();

 System.out.println(Text);

7. To perform Scroll on an application

 js.executeScript("window.scrollBy(0,500)");

Types of Software Testing

 Software Testing:

•  The process of finding errors in the developed product.
•  Testing the software whether it is working according to the requirement.

Two ways of Testing:

 1. Manual Testing

 2. Automation Testing

Manual Testing:

•  Manual testing is verifying the software manually and finding errors without the intervention of any tools.
•  The tester has to execute each test case one by one.
•  They give input and manually verify the output.

Automation Testing:

•  Automation Testing is testing the software with the help of some automation tools like Selenium.
•  The code is run for automating tests and the input data is given to the tool.
•  The output data is compared with the expected results.
•  Automation testing is generally performed for repeated tasks so that time can be saved.

Levels of Testing:

 1. Unit Testing

 2. System Testing

 3. Integration Testing

 4. Acceptance Testing

1. Unit Testing:

•  Unit testing is the first level of testing usually performed by the developers.

Advantage: Error can be detected at an early stage saving time and money to fix it.

2. System Testing:

•  Complete application testing.
•  Done by Testers.
•  Black Box Testing Techniques.
•  FRS and test case document.

System Testing Categories:

•  Usability Testing
•  Functional Testing
•  Performance Testing
•  Security Testing

3. Integration Testing:

•  Combining/merging modules.
•  Done by Developers.
•  White box testing technique.

4. Acceptance Testing:

•  Getting approval from the client.
•  Done by the client.
•  Satisfying client requirements.

Types of Testing:

 1. Functional Testing

 2. Non-Functional Testing

1. Functional Testing:

•  Testing the behaviour of the application.
•  Based on how well the system is working.

Alpha Testing:

•  The application is tested for the first time.
•  Done under the supervision of developers.

Beta Testing:

•  The application is tested a second time.
•  Before the final release of the software is released to users for testing.

Smoke Testing:

•  Testing the primary functionality of the application.

Sanity Testing:

•  Testing the minor functionality of the application.

Regression Testing:

•  Testing the whole application to check whether new requirement changes affect previous functionality.

Retesting:

•  Testing only the bugs fixed by the developers.

2. Non-Functional Testing:

•  Based on how well the system is performed.
•  Testing the performed to verify the non-functional requirements of the application.

Usability Testing:

•  User Friendly
•  Look and Feel
•  Ease of use
•  Speed in Interface
•  Context Sensitiveness

Performance Testing:

•  Load Testing
•  Stress Testing
•  Data/Volume Testing

Security Testing:

•  Protecting from unauthorized access.

Compatibility Testing:

•  OS Compatability - Testing in multiple OS.
•  Browser Compatability - Testing in multiple Browsers.

Software Testing Interview Questions and Answers:

1. STLC - stands for Software Testing Life Cycle.

  Requirements and analysis, test planning, test design, test execution, error report, solving the error, re-test, test close.

2. Software Quality:

•   Quality is ensured by two sets of activities. verification and validation.

  Verification - It involves activities like document review, test case review, walk-throughs, and inspections.

  Validation - It involves activities like functional testing and automation testing.

3. Workflow of Functional Testing:

•   Create input values.
•   Execute test cases.
•   Compare actual and expected output.

4. Client Expectation:

  Completeness, correctness, quality.

5. Tester Responsibility: (Zero bugs and 100% quality)

•   Execute test cases
•   Positive and Negative Conditions.
•   Manual or Automation tools.

 6. Error - Done by the developer in code

   Bug - Tester identifies the errors.

7. Quality - Meeting client requirements.

   Customer needs or expectations.

8. How to measure Quality:

  Functionality, Usability, Reliability, Performance, and Scalability.

9. Bug - unexpected or incorrect result.

10. Main Goal of Testing:

  Expected Result = Actual Result (Test Pass)

  Expected Result != Actual Result (Test Fail)

11. Severity - the impact of a bug on the software.

   Priority - is how soon a bug needs to be fixed.

Java Programming Examples

 1. Java Syntax:
package selenium;
public class Java_Examples {
  public static void main(String[] args) {
System.out.println("suriya parithy");
}
}

2. Data types and variables:
package selenium;
public class Java_Examples {
  public static void main(String[] args) {
  // type variableName = value;
  String name = "suriya";
  int myNum = 15;
  float myFloatNum = 5.99f;
  char myLetter = 'S';
  boolean myBool = true;
  
  System.out.println(name);
  System.out.println(myNum);
  System.out.println(myFloatNum);
  System.out.println(myLetter);
  System.out.println(myBool);
  }
}

3. Java Operators:
package selenium;
public class Java_Examples {
  public static void main(String[] args) {
  int sum1 =100 + 200;
  int sum2 = sum1 + 300;
  int x = 4;
  int y = 6;
  System.out.println(sum1);
  System.out.println(sum2);
  System.out.println(x-y);
  System.out.println(x == y); // returns false because 4 is not equal to 6
  System.out.println(x != y); // returns true because 4 is not equal to 6
  System.out.println(x > y); 
  System.out.println(x < y);
  System.out.println(x > 3 && x < 10); // returns true because 4 is greater than 3 AND 4 is less than 10
  System.out.println(x > 3 || x < 5); // returns true because one of the conditions are true(4 is greater than 3)
  }
}

4. Java Strings:
package selenium;
public class Java_Examples {
  public static void main(String[] args) {
  String name = "suriya parithy";
  System.out.println("The length of the name string is:" + name.length());
  System.out.println(name.toUpperCase()); // Outputs "SURIYA PARITHY"
  System.out.println(name.toLowerCase()); // Outputs "suriya parithy"
  }
}
