NuGet package - Selenium WebDriver ChromeDriver

What's this?

This NuGet package installs Chrome Driver (Win32, macOS, macOS arm64, and Linux64) for Selenium WebDriver into your Unit Test Project.

"chromedriver(.exe)" does not appear in Solution Explorer, but it is copied to the output folder from the package source folder when the build process.

NuGet package restoring ready, and no need to commit "chromedriver(.exe)" binary into source code control repository.

Warning
Since Selenium WebDriver version 4.6 was released in November 2022 or later, it has contained "Selenium Manager", which will automatically download the most suitable version and platform WebDriver executable file. So now, you can run applications that use Selenium and manipulates web browsers without this package. However, due to compatibility and some offline scenarios, we intend to keep this package for the time being.

How to install?

For example, enter the following command in a terminal console where the current folder is the project folder.

If you are using Chrome version 139:

dotnet add package Selenium.WebDriver.ChromeDriver --version 139.0.7258.5200-beta

If you are using Chrome version 138:

dotnet add package Selenium.WebDriver.ChromeDriver --version 138.0.7204.16800

If you are using Chrome version 137:

dotnet add package Selenium.WebDriver.ChromeDriver --version 137.0.7151.11900

Cross-platform building and publishing

By default - it depends on the OS running the build process

By default, the platform type of the web driver file copied to the output folder depends on the OS running the build process.

• When you build the project which references the NuGet package of chromedriver on Windows OS, win32 version of chromedriver will be copied to the output folder.
• When you build it on macOS on Intel CPU hardware, macOS x64 version of chromedriver will be copied to the output folder.
• When you build it on macOS on Apple CPU hardware, macOS Arm64 version of chromedriver will be copied to the output folder.
• When you build it on any Linux distributions, Linux x64 version of chromedriver will be copied to the output folder.

Method 1 - Specify "Runtime Identifier"

When you specify the "Runtime Identifier (RID)" explicitly, the platform type of the driver file is the same to the RID which you specified. (it doesn't depends on the which OS to use for build process.)

You can specify RID as a MSBuild property in a project file,

<PropertyGroup>
  <RuntimeIdentifier>win-x64</RuntimeIdentifier>
</PropertyGroup>

or, as a command-line -r option for dotnet build command.

> dotnet build -r:osx-x64

• When the RID that starts with "win" is specified, win32 version of chromedriver will be copied to the output folder.
• When the RID that starts with "osx" and ends with "x64" is specified, macOS x64 version of chromedriver will be copied to the output folder.
• When the RID that starts with "osx" and ends with "arm64" is specified, macOS Arm64 version of chromedriver will be copied to the output folder.
• When the RID that starts with "linux" is specified, Linux x64 version of chromedriver will be copied to the output folder.

If you specify another pattern of RID like "linux-x64", the platform type of the web driver file which will be copied to the output folder depends on the OS running the build process. (default behavior.)

Method 2 - Specify "WebDriverPlatform" msbuild property

You can control which platform version of chromedriver will be copied by specifying "WebDriverPlatform" MSBuild property.

"WebDriverPlatform" MSBuild property can take one of the following values:

• "win32"
• "mac64"
• "mac64arm"
• "linux64"

You can specify "WebDriverPlatform" MSBuild property in a project file,

<PropertyGroup>
  <WebDriverPlatform>win32</WebDriverPlatform>
</PropertyGroup>

or, command-line -p option for dotnet build command.

> dotnet build -p:WebDriverPlatform=mac64

The specifying "WebDriverPlatform" MSBuild property is the highest priority method to control which platform version of the chromedriver will be copied.

If you run the following command on Windows OS,

> dotnet build -r:linux-x64 -p:WebDriverPlatform=mac64

The driver file of macOS x64 version will be copied to the output folder.

How to include the driver file into published files?

"chromedriver(.exe)" isn't included in published files on default configuration. This behavior is by design.

If you want to include "chromedriver(.exe)" into published files, please define _PUBLISH_CHROMEDRIVER compilation symbol.

Another way, you can define PublishChromeDriver property with value is "true" in MSBuild file (.csproj, .vbproj, etc...) to publish the driver file instead of define compilation symbol.

  <Project ...>
    ...
    <PropertyGroup>
      ...
      <PublishChromeDriver>true</PublishChromeDriver>
      ...
    </PropertyGroup>
...
</Project>

You can also define PublishChromeDriver property from the command line -p option for dotnet publish command.

> dotnet publish -p:PublishChromeDriver=true

Note

PublishChromeDriver MSBuild property always override the condition of define _PUBLISH_CHROMEDRIVER compilation symbol or not. If you define PublishChromeDriver MSBuild property with false, then the driver file isn't included in publish files whenever define _PUBLISH_CHROMEDRIVER compilation symbol or not.

Appendix

The numbering of the package version

The rule of the version number of this package is:

chromedriver version MAJOR.MINOR.BUILD.PATCH + package version (2 digit)

For example, 2nd package release for the chromedriver ver.1.2.3.4, the package version is 1.2.3.4 + 02 → 1.2.3.402.

Sometime multiple packages for the same chromedriver version may be released by following example reasons.

• Packaging miss. (the package included invalid version of the driver files)
• Fixing bug of the build script, or improving the build script.

Where is chromedriver.exe saved to?

chromedriver(.exe) exists at
" /packages/Selenium.WebDriver.ChromeDriver. /driver/ "
folder.

 {Solution folder}/
  +-- packages/
  |   +-- Selenium.WebDriver.ChromeDriver.{version}/
  |       +-- driver/
  |       |   +-- win32
  |       |       +-- chromedriver.exe
  |       |   +-- mac64
  |       |       +-- chromedriver
  |       |   +-- mac64arm
  |       |       +-- chromedriver
  |       |   +-- linux64
  |       |       +-- chromedriver
  |       +-- build/
  +-- {project folder}/
      +-- bin/
          +-- Debug/
          |   +-- chromedriver(.exe) (copy from above by build process)
          +-- Release/
              +-- chromedriver(.exe) (copy from above by build process)

And package installer configure MSBuild task such as .csproj to copy chromedriver(.exe) into the output folder during the build process.
