npm install selenium-webdriver -- save

This will download and install the Selenium WebDriver bundle into your project ’ s node_modules folder and add it as a dependency in your package.json file.

Step 5: Install Browser Driver

Depending on the browser you desire to automate, you & # 8217; ll need to install the respective WebDriver. For example, if you & # 8217; re using Chrome, you necessitate to download ChromeDriver.

After downloading the driver, ensure it ’ s accessible by adding the location to your system & # 8217; s PATH or specify its route now in your Selenium script.

Step 6: Verify the Installation

To ensure that everything is set up correctly, create a simple JavaScript file, for example, test.js, in your task pamphlet. Add the following code to open a browser apply Selenium:

const {Builder} = require ('selenium-webdriver '); const driver = new Builder () .forBrowser ('chrome ') .build (); driver.get ('http: //www.google.com ') .then (() = & gt; driver.quit ());

Save the file and run it in the depot with:

node test.js

If everything is set up right, this book will open Chrome, navigate to Google ’ s homepage, and so close the browser.

Setting up and Running the Selenium Script

Once you & # 8217; ve installed Selenium WebDriver and set up your project, you can start compose and pass Selenium automation scripts. Here ’ s how to set up and execute your first Selenium script.

Step 1: Create a New JavaScript File

In your project folder, make a new JavaScript file, such as automation.js. This file will contain the code that automatize the browser interaction.

Step 2: Import the Required Selenium Modules

To interact with Selenium WebDriver, you foremost need to import the necessary module. At the top of your JavaScript file, add the undermentioned code:

const {Builder, By, Key, until} = require ('selenium-webdriver ');

• Builder:Helps create a new WebDriver instance.
• By:Allows you to place web elements on the page (e.g., by ID, gens, or class).
• Key:Used for simulating keyboard inputs.
• until:Helps you define weather that the script should look for (e.g., until an factor is visible).

Step 3: Set Up the WebDriver

Next, you need to make a new instance of the WebDriver to control the browser. In this example, use Chrome, but you can use early browsers by modifying the browser parameter. Here & # 8217; s how you set up the WebDriver for Chrome:

let driver = new Builder () .forBrowser ('chrome ') .build ();

Step 4: Navigate to a Website

After setting up the WebDriver, the next step is to navigate to a website.

driver.get ('http: //www.google.com ');

This command will open Google in the browser you specified (Chrome in this case).

Selenium WebDriver allows you to interact with assorted elements on a web page. You can observe component by their ID, name, class, and more. Let ’ s say you require to search for a term on Google. You can locate the search box by its name (q) and type in a query:

driver.findElement (By.name (' q ')) .sendKeys ('Selenium WebDriver ');

This line finds the search box on Google and types the search term & # 8220;Selenium WebDriver& # 8221; into it.

Step 6: Submit the Search

To submit the lookup query, you can simulate pressing the & # 8216;Enter& # 8216; key using Selenium & # 8217; s Key faculty. Here & # 8217; s how you do that:

driver.findElement (By.name (' q ')) .sendKeys (Key.RETURN);

Step 7: Wait for an Element to Appear (Optional)

Selenium allows you to wait for elements to go available before execute actions. For example, if you want to wait for the Google event to load, you can use until to wait for a specific condition. Here ’ s how to look until the search result appear:

driver.wait (until.elementLocated (By.id ('search ')), 10000);

This waits for the element with the ID search (the results container) to appear, with a timeout of 10 seconds.

Step 8: Close the Browser

Once the automation project are dispatch, you should close the browser to free up resources. You can do this by calling the quit () method on the driver:

driver.quit ();

Step 9: Run the Script

Now that you ’ ve set up your script, you can run it. Open your terminal and navigate to your project leaflet. Run the script with the next command:

node automation.js

If everything is set up correctly, the handwriting will open Google in Chrome, type & # 8220;Selenium WebDriver& # 8221; in the search box, state the search, wait for the results, and then close the browser.
