Powershell: Use latest selenium version

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the selenium module from the powershell gallery outdated is outdated.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

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.

PS D:\MyProject> $sNewtonSoftURL='https://www.nuget.org/api/v2/package/Newtonsoft.Json' 
PS D:\MyProject> $sSeleniumWebdriverURL='https://www.nuget.org/api/v2/package/Selenium.WebDriver'
PS D:\MyProject> $sChromWebdriverURL='https://www.nuget.org/api/v2/package/Selenium.WebDriver.ChromeDriver'
PS D:\MyProject> $sEdgeWebdriverURL='https://www.nuget.org/api/v2/package/Selenium.WebDriver.MSEdgeDriver'
PS D:\MyProject> $sFireFoxWebdriverURL='https://www.nuget.org/api/v2/package/Selenium.WebDriver.GeckoDriver'
PS D:\MyProject> $sNewtonSoftDLL=[System.IO.Path]::Combine($PWD,"Newtonsoft.Json.dll")
PS D:\MyProject> $sSeleniumWebdriverDLL=[System.IO.Path]::Combine($PWD,"WebDriver.dll")
PS D:\MyProject> $sChromeWebdriverEXE=[System.IO.Path]::Combine($PWD,"chromedriver.exe")
PS D:\MyProject> $sEdgeWebdriverEXE=[System.IO.Path]::Combine($PWD,"msedgedriver.exe")
PS D:\MyProject> $sFirefoxWebdriverEXE=[System.IO.Path]::Combine($PWD,"geckodriver.exe")

Download the files

PS D:\MyProject> $sTempNewtonSoftNUGETPackage=[System.IO.Path]::GetTempFileName()
PS D:\MyProject> Invoke-WebRequest -Uri $sNewtonSoftURL -OutFile $sTempNewtonSoftNUGETPackage
PS D:\MyProject> $sNewtonSoftNUGETPackage = [System.IO.Compression.ZipFile]::OpenRead($sTempNewtonSoftNUGETPackage)
PS D:\MyProject> $sNewtonSoftNUGETPackage.Entries | ?{$_.FullName -eq "lib/net45/Newtonsoft.Json.dll" } | %{
    [System.IO.Compression.ZipFileExtensions]::ExtractToFile($_,$sNewtonSoftDLL)
}
PS D:\MyProject> $sTempSeleniumWebdriverNUGETPackage=[System.IO.Path]::GetTempFileName()
PS D:\MyProject> Invoke-WebRequest -Uri $sSeleniumWebdriverURL -OutFile $sTempSeleniumWebdriverNUGETPackage
PS D:\MyProject> $sSeleniumWebdriverNUGETPackage = [System.IO.Compression.ZipFile]::OpenRead($sTempSeleniumWebdriverNUGETPackage)
PS D:\MyProject> $sSeleniumWebdriverNUGETPackage.Entries | ?{$_.FullName -eq "lib/netstandard2.0/WebDriver.dll" } | %{
    [System.IO.Compression.ZipFileExtensions]::ExtractToFile($_,$sSeleniumWebdriverDLL)
}

PS D:\MyProject> $sTempChromeWebdriverNUGETPackage=[System.IO.Path]::GetTempFileName()
PS D:\MyProject> Invoke-WebRequest -Uri $sChromWebdriverURL -OutFile $sTempChromeWebdriverNUGETPackage
PS D:\MyProject> $sChromeWebdriverNUGETPackage = [System.IO.Compression.ZipFile]::OpenRead($sTempChromeWebdriverNUGETPackage)
PS D:\MyProject> $sChromeWebdriverNUGETPackage.Entries | ?{$_.FullName -eq "driver/win32/chromedriver.exe" } | %{
    [System.IO.Compression.ZipFileExtensions]::ExtractToFile($_,$sChromeWebdriverEXE)
}

Download and load assembly and start the browser with 2 functions

    }
    return $driver
}

Some examples. Load the functions (i.e. copy & paste to the powershell window) then

PS D:\> mkdir MySeleniumProject
PS D:\> cd D:\MySeleniumProject
PS D:\MySeleniumProject> $WebDriver = Start-Browser Chrome
PS D:\MySeleniumProject> $WebDriver.Url = "https://www.ebay.de"

Page reload

$WebDriver.navigate().refresh()

Get EBay price

$WebDriver.FindElements([OpenQA.Selenium.By]::ClassName("x-price-primary")).FindElements([OpenQA.Selenium.By]::TagName("span")).Text

Bit button

$WebDriver.FindElements([OpenQA.Selenium.By]::XPath("//button[@data-elementid='MaxBidId']"))
$WebDriver.FindElements([OpenQA.Selenium.By]::XPath("//button[@data-elementid='MaxBidId']")).Click()

Get price input span element

$WebDriver.FindElements([OpenQA.Selenium.By]::XPath("//span[contains(@class,'textbox app-input-price__input textbox__empty')]"))

Get the input tag (child of span)

$InputTag=($WebDriver.FindElements([OpenQA.Selenium.By]::XPath("//span[contains(@class,'textbox app-input-price__input textbox__empty')]"))).findelements([OpenQA.Selenium.By]::TagName("input"))

Send backspaces to delete input

for($i=12;$i -ge 0;$i--)
{
$InputTag.SendKeys([OpenQA.Selenium.Keys]::Backspace)
}

Send price

$InputTag.SendKeys("10,00")
