## QUE 1 : Explain difference between Selenium IDE, Selenium WebDriver and Selenium grid

**Selenium IDE:**

- Selenium IDE is a record-and-playback tool primarily used for creating and executing Selenium tests without writing code.
- It's a browser extension available for Chrome and Firefox, allowing users to record interactions with the browser and generate automated test scripts in various programming languages like Java, Python, Ruby and Selenese (Selenium’s own scripting language).
- Selenium IDE is suitable for quick test case creation and prototyping but may lack the robustness and flexibility of WebDriver for complex testing scenarios.

**Selenium WebDriver:**

- Selenium WebDriver is the most powerful component of the Selenium suite, providing a programming interface for creating and executing test scripts.
- It allows testers to write code in programming languages like Java, Python, C#, etc., to interact with web elements and automate browser actions.
- WebDriver directly communicates with the browser using its native automation support, providing more control and flexibility over browser interactions compared to Selenium IDE.
- WebDriver supports various browsers such as Chrome, Firefox, Safari, Edge, etc., and enables testing across different operating systems.

**Selenium Grid:**

- Selenium Grid is a tool used for parallel execution of Selenium tests across multiple machines and browsers simultaneously.
- It consists of a hub and multiple nodes. The hub acts as a central point where test requests are sent, and nodes are remote machines (physical or virtual) where tests are executed.
- Selenium Grid enables testers to distribute test execution, reducing the overall test execution time and increasing test coverage.

## QUE 3 : What is Selenium and how it is useful in automation testing

Selenium is an open-source automation testing framework primarily used for automating web applications. It provides a suite of tools that facilitate the automation of web browsers for testing purposes. Selenium allows testers to automate interactions with web elements, such as clicking buttons, entering text, submitting forms, and verifying expected behavior

**Here's how Selenium is useful in automation testing:**

_<u>Cross-browser Testing:</u>_ Selenium supports multiple web browsers such as Chrome, Firefox, Safari, Edge, and Opera. Test scripts written with Selenium can be executed across different browsers, ensuring that web applications function correctly regardless of the browser being used.

_<u>Cross-platform Testing:</u>_ Selenium enables testing across various operating systems like Windows, macOS, and Linux. This ensures that web applications behave consistently across different platforms.

_<u>Automation of Repetitive Tasks:</u>_ Selenium automates repetitive testing tasks, such as regression testing, where testers need to repeatedly validate the functionality of an application after code changes. By automating these tasks, testers can save time and effort, allowing them to focus on more complex testing scenarios.

_<u>Improved Test Coverage:</u>_ Automated tests created with Selenium can cover a wide range of test scenarios, including positive and negative cases, edge cases, and user interactions. This helps in achieving comprehensive test coverage, identifying bugs early in the development cycle, and improving the overall quality of the software.

<u>_Integration with Continuous Integration (CI) Systems:_</u> Selenium can be integrated with CI systems like Jenkins, Bamboo, or Travis CI, enabling the execution of automated tests as part of the continuous integration and continuous deployment (CI/CD) pipeline. This ensures that new code changes are thoroughly tested before being deployed to production, reducing the risk of introducing bugs into the application.

<u>_Support for Multiple Programming Languages:_</u> Selenium WebDriver, the core component of Selenium, supports multiple programming languages such as Java, Python, C#, Ruby, and JavaScript. This allows testers to write test scripts in their preferred programming language, making it accessible to a wide range of users with different skill sets.

## QUE 4 : What are all browser driver used in selenium

Selenium WebDriver supports various browser drivers, each corresponding to a specific web browser. Here are the commonly used browser drivers in Selenium
1. ChromeDriver
2. GeckoDriver (FirefoxDriver)
3. InternetExplorerDriver
4. EdgeDriver
5. SafariDriver
6. OperaDriver
7. ChromiumDriver

## QUE 5 : What are the steps to create a simple WebDriver script. Explained with code.

STEP 1 ->
Import the necessary Selenium WebDriver classes and any other required libraries.

_**import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;**_

STEP 2 ->
Setup WebDriver using WebDriverManager for chrome

_**WebDriverManager.chromedriver().setup();**_

STEP 3 ->
Initialize WebDriver instance

_**WebDriver driver = new ChromeDriver();**_

STEP 4 ->
Use the driver instance to navigate to a specific URL.

_**driver.get(""https://www.google.com/"");**_

STEP 5 ->
Perform Actions, Interact with the web elements on the page using various WebDriver methods like findElement(), sendKeys(), click(), etc.
Here I have found the web element of search text field using findElement method and by using sendKeys method I have entered value "Selenium Browser Driver" to it. Then I used keys.Enter function to perform enter option in keyboard

_**driver.findElement(By.name("q")).sendKeys("Selenium Browser Driver", Keys.ENTER);**_

STEP 6 ->
Close the WebDriver instance after the test execution is complete.

_**driver.quit();**_
