All the previous answers are correct. Following is the little deep dive into the problem and solution.
The driver constructor in Selenium for example
<pre><code>WebDriver driver = new ChromeDriver();
</code></pre>
searches for the driver executable, in this case the Google Chrome driver searches for a Chrome driver executable. In case the service is unable to find the executable, the exception is thrown.
This is where the exception comes from (note the check state method)
<pre><code> /**
 *
 * @param exeName Name of the executable file to look for in PATH
 * @param exeProperty Name of a system property that specifies the path to the executable file
 * @param exeDocs The link to the driver documentation page
 * @param exeDownload The link to the driver download page
 *
 * @return The driver executable as a {@link File} object
 * @throws IllegalStateException If the executable not found or cannot be executed
 */
 protected static File findExecutable(
 String exeName,
 String exeProperty,
 String exeDocs,
 String exeDownload) {
 String defaultPath = new ExecutableFinder().find(exeName);
 String exePath = System.getProperty(exeProperty, defaultPath);
 checkState(exePath != null,
 &quot;The path to the driver executable must be set by the %s system property;&quot;
 + &quot; for more information, see %s. &quot;
 + &quot;The latest version can be downloaded from %s&quot;,
 exeProperty, exeDocs, exeDownload);

 File exe = new File(exePath);
 checkExecutable(exe);
 return exe;
 }
</code></pre>
The following is the check state method which throws the exception:
<pre><code> /**
 * Ensures the truth of an expression involving the state of the calling instance, but not
 * involving any parameters to the calling method.
 *
 * &lt;p&gt;See {@link #checkState(boolean, String, Object...)} for details.
 */
 public static void checkState(
 boolean b,
 @Nullable String errorMessageTemplate,
 @Nullable Object p1,
 @Nullable Object p2,
 @Nullable Object p3) {
 if (!b) {
 throw new IllegalStateException(format(errorMessageTemplate, p1, p2, p3));
 }
 }
</code></pre>
SOLUTION: set the system property before creating driver object as follows.
<pre><code>System.setProperty(&quot;webdriver.gecko.driver&quot;, &quot;path/to/chromedriver.exe&quot;);
WebDriver driver = new ChromeDriver();
</code></pre>
The following is the code snippet (for Chrome and Firefox) where the driver service searches for the driver executable:
Chrome:
<pre><code> @Override
 protected File findDefaultExecutable() {
 return findExecutable(&quot;chromedriver&quot;, CHROME_DRIVER_EXE_PROPERTY,
 &quot;https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver&quot;,
 &quot;http://chromedriver.storage.googleapis.com/index.html&quot;);
 }
</code></pre>
Firefox:
<pre><code>@Override
 protected File findDefaultExecutable() {
 return findExecutable(
 &quot;geckodriver&quot;, GECKO_DRIVER_EXE_PROPERTY,
 &quot;https://github.com/mozilla/geckodriver&quot;,
 &quot;https://github.com/mozilla/geckodriver/releases&quot;);
 }
</code></pre>
where CHROME_DRIVER_EXE_PROPERTY = &quot;webdriver.chrome.driver&quot;
and GECKO_DRIVER_EXE_PROPERTY = &quot;webdriver.gecko.driver&quot;
Similar is the case for other browsers, and the following is the snapshot of the list of the available browser implementation:

To run Selenium WebDriver test cases in Chrome, follow these steps:
<ol>
<li>First of all, set the property and Chrome driver path:
<pre><code>System.setProperty(&quot;webdriver.chrome.driver&quot;, &quot;/path/to/chromedriver&quot;);
</code></pre>
</li>
<li>Initialize the Chrome Driver's object:
<pre><code>WebDriver driver = new ChromeDriver();
</code></pre>
</li>
<li>Pass the URL into the <code>get</code> method of WebDriver:
<pre><code>driver.get(&quot;http://www.google.com&quot;);
</code></pre>
</li>
</ol>

I included the binary into my projects resources directory like so:
<pre><code>src\main\resources\chrome\chromedriver_win32.zip
src\main\resources\chrome\chromedriver_mac64.zip
src\main\resources\chrome\chromedriver_linux64.zip
</code></pre>
Code:
<pre><code>import org.apache.commons.io.IOUtils;

import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public WebDriver getWebDriver() throws IOException {
 File tempDir = Files.createTempDirectory(&quot;chromedriver&quot;).toFile();
 tempDir.deleteOnExit();
 File chromeDriverExecutable;

 final String zipResource;
 if (SystemUtils.IS_OS_WINDOWS) {

 try (InputStream is = getClass().getResourceAsStream(&quot;/chrome/&quot; + zipResource)) {

I tried this
<pre class="lang-java prettyprint-override"><code>WebDriver driver = new ChromeDriver();
</code></pre>
But I'm getting the error as
<blockquote>
Failed tests: setUp(com.TEST): The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see <a href="http://code.google.com/p/selenium/wiki/ChromeDriver" rel="nofollow noreferrer">code here</a> .

How can I make Chrome test the Selenium WebDriver test cases?
