Powershell: Use latest selenium version

Leave a comment

Hi,

the selenium module from the powershell gallery outdated is outdated.

Here is my method to use the latest selenium nuget version for a script with Chrome.

First load requiered assemblies

1
PS D:\> [System.Reflection.Assembly]::LoadWithPartialName("System.IO.Compression.FileSystem")

Create a project directory

PS D:\> mkdir D:\MyProject
PS D:\> cd D:\MyProject
PS D:\> $PWD="D:\MyProject"

Define URLs for Selenium.WebDriver, Newtonsoft.Json,Chromedriver, Edgedriver and Firefox. URLs are the link to nuget packages which are zip conpressed files.
