The code imports necessary classes and functions from the selenium-webdriver module and defines a function closeAllWindows that closes all browser windows except the one specified by the keep argument. The function creates a new instance of WebDriver, gets an array of window handles, and iterates over them to close all windows except the one specified by keep.

Run example

npm run import -- "close all windows"

close all windows

const { WebDriver, Capabilities, Session } = require('selenium-webdriver')
const createExecutor = importer.import("selenium executor")

const LOCAL_URL = 'http://localhost:4444/wd/hub';

async function closeAllWindows(driver, sessionId, keep) {
  let driver2 = new WebDriver(
    new Session(sessionId, Capabilities.chrome()), createExecutor(Promise.resolve(LOCAL_URL)))

  try {
    let windows = await driver2.getAllWindowHandles()
    console.log('closing session ' + sessionId[1] + ' windows ' + windows)
    for(let i = 0; i < windows.length; i++) {
      if(windows[i] != keep) {
        await driver2.switchTo().window(windows[i])
        await driver2.close()
      }
    }
  } catch (e) {
    console.log(e)
  }
}

module.exports = closeAllWindows

const { Builder, Capabilities, until } = require('selenium-webdriver');
const createExecutor = require('selenium-executor').default;

const LOCAL_URL = 'http://localhost:4444/wd/hub';

/**

async function closeAllWindows(driver, sessionId, keep) {
  // Create a new WebDriver instance with the specified session ID and capabilities
  const driver2 = await new Builder()
   .usingServer(LOCAL_URL)
   .withCapabilities(Capabilities.chrome())
   .build();

  try {

    const windows = await driver2.getAllWindowHandles();

    console.log(`Closing session ${sessionId.slice(1)} windows ${windows}`);

    // Iterate over all window handles and close the ones that are not 'keep'
    for (let i = 0; i < windows.length; i++) {
      if (windows[i]!== keep) {
        // Switch to the current window and close it
        await driver2.switchTo().window(windows[i]);
        await driver2.close();
      }
    }

Code Breakdown

Imports

const { WebDriver, Capabilities, Session } = require('selenium-webdriver')
const createExecutor = importer.import('selenium executor')

• The code imports the WebDriver, Capabilities, and Session classes from the selenium-webdriver module.
• It also imports a function createExecutor from a module named selenium executor using the importer module.

Constants

const LOCAL_URL = 'http://localhost:4444/wd/hub';

• A constant LOCAL_URL is defined, which represents the URL of a Selenium WebDriver hub on localhost.

Function

async function closeAllWindows(driver, sessionId, keep) {
  //...
}

• A function closeAllWindows is defined, which takes three arguments:
  • driver: an instance of WebDriver
  • sessionId: a session ID string
  • keep: a value to keep open

Function Body

let driver2 = new WebDriver(
  new Session(sessionId, Capabilities.chrome()), createExecutor(Promise.resolve(LOCAL_URL)))

//...

• A new instance of WebDriver is created, using a Session instance with the provided sessionId and Capabilities.chrome().
• The createExecutor function is used to create an executor, which is passed to the WebDriver constructor.

try {
  let windows = await driver2.getAllWindowHandles()
  console.log('closing session'+ sessionId[1] +'windows'+ windows)
  for(let i = 0; i < windows.length; i++) {
    if(windows[i]!= keep) {
      await driver2.switchTo().window(windows[i])
      await driver2.close()
    }
  }
} catch (e) {
  console.log(e)
}

• The getAllWindowHandles method is used to get an array of window handles.
• A for loop is used to iterate over the window handles, and if a handle is not equal to the keep value, the corresponding window is closed.

Export

module.exports = closeAllWindows

• The closeAllWindows function is exported as a module.
