Add Command Line Interface (CLI) Args on PhantomJS

To add a command-line interface (CLI) and command-line arguments (args) to PhantomJS when using Selenium WebDriver in Node.js, you can modify your existing code as follows. I’ll provide you with a step-by-step guide and also explain the changes made:

const webdriver = require('selenium-webdriver');
const { Builder } = webdriver;
const phantomjs = require('phantomjs-prebuilt');

// Define your PhantomJS command-line arguments here
const phantomjsArgs = [
  '--load-images=false',
  // Add any other arguments you need here
];

// Set up capabilities with the CLI arguments
const capabilities = webdriver.Capabilities.phantomjs();
capabilities.set('phantomjs.cli.args', phantomjsArgs);

// Set the path to the PhantomJS executable
const phantomjsPath = phantomjs.path;
capabilities.set('phantomjs.binary.path', phantomjsPath);

// Create a WebDriver instance with the configured capabilities
const driver = new Builder()
  .withCapabilities(capabilities)
  .build();

// Example usage: navigate to a webpage
driver.get('https://example.com')
  .then(() => {
    console.log('Page title:', driver.getTitle());
  })
  .catch(error => {
    console.error('Error:', error);
  });

// Don't forget to quit the driver when done
driver.quit();

Here are the changes made to your original code:

1. Import the necessary modules: We import the required modules and classes using destructuring for cleaner code.

2. Define PhantomJS command-line arguments: You can define your PhantomJS command-line arguments in the phantomjsArgs array. In this example, we have set --load-images=false as one argument. You can add any other arguments you need to this array.

3. Set capabilities for PhantomJS: We create a capabilities object for PhantomJS using webdriver.Capabilities.phantomjs() and set the CLI arguments using capabilities.set('phantomjs.cli.args', phantomjsArgs).

4. Specify the path to the PhantomJS executable: We set the path to the PhantomJS executable using capabilities.set('phantomjs.binary.path', phantomjsPath), where phantomjsPath is obtained from the phantomjs-prebuilt package.

5. Create a WebDriver instance: We create a new WebDriver instance using the configured capabilities.

6. Example usage: You can see an example of using the WebDriver to navigate to a webpage and print the page title. You can replace this with your actual automation tasks.

7. Quit the WebDriver: It’s important to call driver.quit() when you are done with the WebDriver to ensure resources are properly released.

Make sure you have the selenium-webdriver and phantomjs-prebuilt packages installed in your Node.js project. You can install them using npm:

1

npm install selenium-webdriver phantomjs-prebuilt

With these modifications, your PhantomJS WebDriver setup will include the specified CLI arguments.
