webdriver-manager

What is webdriver-manager?

The webdriver-manager npm package is a tool for managing WebDriver binaries. It is commonly used to download, update, and start WebDriver binaries for Selenium WebDriver, making it easier to set up and manage the necessary components for running automated browser tests.

What are webdriver-manager's main functionalities?

Download WebDriver binaries

This feature allows you to download the necessary WebDriver binaries for your browser. The `update` method fetches the latest versions of the binaries and stores them locally.

const webdriverManager = require('webdriver-manager');
webdriverManager.update();

Start WebDriver server

This feature starts the WebDriver server, which is necessary for running Selenium WebDriver tests. The `start` method launches the server and makes it ready to accept WebDriver commands.

const webdriverManager = require('webdriver-manager');
webdriverManager.start();

Stop WebDriver server

This feature stops the WebDriver server. The `shutdown` method gracefully stops the server, ensuring that all resources are properly released.

const webdriverManager = require('webdriver-manager');
webdriverManager.shutdown();

Other packages similar to webdriver-manager

selenium-standalone

The selenium-standalone package is similar to webdriver-manager in that it helps manage Selenium WebDriver binaries. It provides commands to install, start, and stop the Selenium server. Compared to webdriver-manager, selenium-standalone offers more flexibility in configuring the Selenium server and supports a wider range of browsers and versions.

chromedriver

The chromedriver package is specifically designed to manage the ChromeDriver binary. It allows you to download, update, and start the ChromeDriver server. While it is more limited in scope compared to webdriver-manager, it is a good choice if you only need to work with Chrome.

geckodriver

The geckodriver package is similar to chromedriver but is focused on managing the GeckoDriver binary for Firefox. It provides functionality to download, update, and start the GeckoDriver server. Like chromedriver, it is more specialized and limited in scope compared to webdriver-manager.

By default, the selenium server will run on http://localhost:4444/wd/hub.

webdriver-manager start

Other useful commands

View different versions of server and driver files:

webdriver-manager status

Clear out the server and driver files. If webdriver-manager start does not work, try to clear out the saved files.

webdriver-manager clean

Running / stopping server in background process (stopping is not yet supported on standalone server 3.x.x):

webdriver-manager start --detach
webdriver-manager shutdown

Help commands

Wedriver-manager has a main help option: webdriver-manager help. There are also other built in help menus for each of the commands. So for example, if you would like to look up all the flag options you can set in update, you could run webdriver-manager update help.

Here are a list of all the commands with help:

webdriver-manager update help
webdriver-manager start help
webdriver-manager clean help
webdriver-manager status help
