Info
Built-in manager was released by Selenium "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.

Build status NuGet

WebDriverManager.Net

Table of contents

Info

This small library aimed to automate the Selenium WebDriver binaries management inside a .Net project.

If you have ever used Selenium WebDriver, you probably know that in order to use some browsers (for example Chrome) you need to download a binary which allows WebDriver to handle the browser. In addition, the absolute path to this binary must be set as part of the PATH environment variable or manually copied to build output folder (working directory).

This is quite annoying since it forces you to link directly this binary in your source code. In addition, you have to check manually when new versions of the binaries are released. This library comes to the rescue, performing in an automated way all this dirty job for you.

WebDriverManager is open source, released under the terms of MIT license.

Installation

WebDriverManager.Net can be downloaded from NuGet. Use the GUI or the following command in the Package Manager Console:

PM> Install-Package WebDriverManager

Usage

Target is netstandard2.0.

After installation you can let WebDriverManager.Net to do manage WebDriver binaries for your application/test. Take a look to this NUnit example which uses Chrome with Selenium WebDriver:

using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using WebDriverManager;
using WebDriverManager.DriverConfigs.Impl;

namespace Test
{
    [TestFixture]
    public class Tests
    {
        private IWebDriver _webDriver;

        [SetUp]
        public void SetUp()
        {
            new DriverManager().SetUpDriver(new ChromeConfig());
            _webDriver = new ChromeDriver();
        }

        [TearDown]
        public void TearDown()
        {
            _webDriver.Quit();
        }

        [Test]
        public void Test()
        {
            _webDriver.Navigate().GoToUrl("https://www.google.com");
            Assert.True(_webDriver.Title.Contains("Google"));
        }
    }
}

Notice that simply adding new DriverManager().SetUpDriver(<config>) does magic for you:

  1. It checks the latest version of the WebDriver binary file
  2. It downloads the binary WebDriver if it is not present in your system

So far, WebDriverManager supports Chrome, Microsoft Edge, Firefox(Marionette), Internet Explorer, Opera or PhantomJS configs (just change to preferred config):

new ChromeConfig();
new EdgeConfig();
new FirefoxConfig();
new InternetExplorerConfig();
new OperaConfig();
new PhantomConfig();

Advanced

You can use WebDriverManager in two ways:

  1. Automatic
  2. Manual

Automatic way:

new DriverManager().SetUpDriver(new <Driver>Config());

You can also specify version:
new DriverManager().SetUpDriver(new ChromeConfig(), "2.25")

Or architecture:
new DriverManager().SetUpDriver(new ChromeConfig(), "Latest", Architecture.X32)

Or version and architecture:
new DriverManager().SetUpDriver(new ChromeConfig(), "2.25", Architecture.X64)

Or you can specify to automatically download a driver matching the version of the browser that is installed in your machine (only for Chrome, Edge, Firefox and Internet Explorer):
new DriverManager().SetUpDriver(new ChromeConfig(), VersionResolveStrategy.MatchingBrowser);

Manual way:

new DriverManager().SetUpDriver(
    "https://chromedriver.storage.googleapis.com/2.25/chromedriver_win32.zip",
    Path.Combine(Directory.GetCurrentDirectory(), "chromedriver.exe")
);

If you want use your own implementation you need to create driver config and use it for set up(ex get, setup and work with phantomjs driver from taobao mirror):

public class TaobaoPhantomConfig : IDriverConfig
{
    public string GetName()
    {
        return "TaobaoPhantom";
    }

    public string GetUrl32()
    {
        return "https://npm.taobao.org/mirrors/phantomjs/phantomjs-<version>-windows.zip";
    }

    public string GetUrl64()
    {
        return GetUrl32();
    }

    public string GetBinaryName()
    {
        return "phantomjs.exe";
    }

    public string GetLatestVersion()
    {
        using (var client = new WebClient())
        {
            var doc = new HtmlDocument();
            var htmlCode = client.DownloadString("https://bitbucket.org/ariya/phantomjs/downloads");
            doc.LoadHtml(htmlCode);
            var itemList =
                doc.DocumentNode.SelectNodes("//tr[@class='iterable-item']/td[@class='name']/a")
                    .Select(p => p.InnerText)
                    .ToList();
            var version = itemList.FirstOrDefault()?.Split('-')[1];
            return version;
        }
    }
}

...

new DriverManager().SetUpDriver(new TaobaoPhantomConfig());

Also you can implement your own services for download binaries and manage variables:

public class CustomBinaryService : IBinaryService
{
    public string SetupBinary(string url, string zipDestination, string binDestination, string binaryName)
    {
        ...
        // your implementation
        ...
    }
}

public class CustomVariableService : IVariableService
{
    public void SetupVariable(string path)
    {
        ...
        // your implementation
        ...
    }
}

...

new DriverManager(new CustomBinaryService(), new CustomVariableService()).SetUpDriver(new FirefoxConfig());

Or you can modify existed drivers and change only necessary fields(same example):

public class TaobaoPhantomConfig : PhantomConfig
{
    public override string GetName()
    {
        return "TaobaoPhantom";
    }

    public override string GetUrl32()
    {
        return "https://npm.taobao.org/mirrors/phantomjs/phantomjs-<version>-windows.zip";
    }
}

...

new DriverManager().SetUpDriver(new TaobaoPhantomConfig());

Using with proxy:

new DriverManager().WithProxy(previouslyInitializedProxy).SetUpDriver(new ChromeConfig());

You can also set the environment variables HTTP_PROXY and/or HTTPS_PROXY to use a proxy when retrieving the drivers. This does not require any changes in the setup of DriverManager in C#.
