title: Selenium WebDriver.ChromeDriver Nuget package installed, but not working for MSTest
body: <p>I have added the <a href="http://www.nuget.org/packages/WebDriver.ChromeDriver/" rel="noreferrer" title="WebDriver.ChromeDriver">WebDriver.ChromeDriver</a> nuget package to my solution, which contains the ChromeDriver.exe file, required for Selenium WebDriver to run automated tests using Chrome. Looking at the package contents, it just contains the file following file:</p>
  
  <p><code>tools\chromedriver.exe</code></p>
  
  <p>What this is <em>supposed</em> to do is add this folder to the PATH environment variable so that <em>chromedriver.exe</em> is accessible via the following code (this is in a UnitTest project using MSTest):</p>
  
  <pre><code>[TestMethod]
  public void LaunchWebsite_Chrome()
  {
       // create ChromeDriver - this should work if chromedriver.exe 
       // is known to the environment PATH variable
       IWebDriver driver = new ChromeDriver();
  
       driver.Navigate().GoToUrl("http://localhost/");
  }
  </code></pre>
  
  <p>However, I am still getting the following exception:</p>
  
  <blockquote>
    <p>The chromedriver.exe file does not exist in the current directory or in a directory on the PATH environment variable. The driver can be downloaded at <a href="http://code.google.com/p/chromium/downloads/list" rel="noreferrer">http://code.google.com/p/chromium/downloads/list</a>.</p>
  </blockquote>
  
  <p>Looking at the nuget documentation, it suggests that anything in the <em>tools</em> folder of the nuget package will get added to the PATH environment variable automatically:</p>
  
  <blockquote>
    <p><a href="http://docs.nuget.org/docs/creating-packages/creating-and-publishing-a-package" rel="noreferrer">http://docs.nuget.org/docs/creating-packages/creating-and-publishing-a-package</a>: The tools folder of a package is for powershell scripts and programs accessible from the Package Manager Console. After the folder is copied to the target project, it is added to the `$env:Path (PATH) environment variable. </p>
  </blockquote>
  
  <p>However, this doesn't seem to be working.  I have even run <code>echo %PATH%</code> on the command line and it doesn't show my tools folder as registered.</p>
  
  <p>What am I doing wrong?</p>
