title: Robotframework: How to use Chromium in Selenium Library with Open Browser?
body: <p>I want to automate tests for a website using Robotframework and Selenium. My test works well with Firefox. However, I would like to use Chromium instead. According to the <a href="http://robotframework.org/SeleniumLibrary/SeleniumLibrary.html#Open%20Browser" rel="nofollow noreferrer">documentation for "Open Browser"</a>, it should work for Chrome. But on my Ubuntu machine I can't use that browser out of the box. </p>
  
  <p>Here is a minimal example:</p>
  
  <pre><code>*** Settings ***
  Library  SeleniumLibrary
  
  *** Test Cases ***
  Open Browser And Check Title
      Open Browser  about:blank  chromium
      Title Should Be  ${EMPTY}
  </code></pre>
  
  <p>It fails with the following error:</p>
  
  <pre><code>ValueError: chromium is not a supported browser.
  </code></pre>
  
  <p>Is there a way to set up chromium for use with Selenium in Robotframework?</p>
  
  <p><strong>EDIT:</strong> This was originally asked for Selenium2Library. When moving to version 3, they dropped the version number from the name. The question has been updated accordingly.</p>
