Its purpose is to simplify the developer experience: if you create a driver object like this:</p> <div class="highlight"><pre tabindex="0" style="background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-text-size-adjust:none;"><code class="language-java" data-lang="java"><span style="display:flex;"><span><span style="color:#000">WebDriver</span><span style="color:#f8f8f8"> </span><span style="color:#000">driver</span><span style="color:#f8f8f8"> </span><span style="color:#ce5c00;font-weight:bold">=</span><span style="color:#f8f8f8"> </span><span style="color:#204a87;font-weight:bold">new</span><span style="color:#f8f8f8"> </span><span style="color:#000">ChromeDriver</span><span style="color:#000;font-weight:bold">();</span><span style="color:#f8f8f8"> </span></span></span></code></pre></div><p>Selenium Manager takes care of detecting whether Chrome is installed, downloading the required driver, and even provisioning a copy of <a href="https://googlechromelabs.github.io/chrome-for-testing/">Chrome for Testing (CfT)</a> if Chrome is not present on the system. This also works for Firefox and Edge, on Windows, Linux, and macOS.</p>
