webdriver-manager update

npm install webdriver-manager -g

If you are following protractor or practicing, then you might have noticed that you do not install or point the driver servers and jar files in our conf file.

If you are from a Selenium background, then you might have used this parameter by setting the system property

The webdriver-manager folder, but as of now, you can only see webdriver-manager files, not a selenium folder. npm install webdriver-manager will not fetch the files, It just enables us to fetch those. webdriver-manager-bin-folder

webdriver-manager update

The Update command will fetch all the required files for the protractor execution. complete-files-webdriver-manager-update


I know the obvious question in your mind. Why are you showing the global installation when you have not used -g at all.?

webdriver-manager update

The above command will install globally because you are accessing the webdriver-manager and it is global, not local.

webdriver-manager update locally

Local installation of these drivers is not possible, so you got to depend on the global installation.

  • start : start up the selenium server

By default, the selenium server will run on http://localhost:4444/wd/hub. This command was used in very earlier versions, but now using this command has no use.
