Headless w/ Xvfbhttp://elementalselenium.com/tips/38-headless
Why use it?
Ideal for running small test suites on a headless machine e.g., a Continuous Integration (CI) Server
Headless w/ GhostDriverhttp://elementalselenium.com/tips/46-headless-ghostdriver
Step 2 - Start PhantomJS w/ WebDriver flag
Step 1 - Download PhantomJShttp://phantomjs.org/download.html
Step 3 - Connect Your Test to PhantomJS using Selenium Remote
NOTEYou can also connect PhantomJS to a Selenium Grid http://bit.ly/ghost-driver-grid
A Visual Testing Primer• check that an application’s UI appears correctly to its users
• goal: find visual bugs before the user does
• e.g., font, layout, rendering issues
• can also be used to verify content
• e.g., charts, dashboards, etc.
• hundreds of assertions for a few lines of code
• at least 16 open source solutions available to choose from
Visual Testing Challenges
• Managing complexity
• False positives
• e.g., shifting content, dynamic content, typos

HTTP Status Codeshttp://elementalselenium.com/tips/17-retrieve-http-status-codes
Configuration
• Use a proxy server to capture the traffic from your Selenium test(s)
• Find the status code for the action you’re interested in (e.g., visiting a URL)
• Assert that the status code is what you expect
Blacklistinghttp://elementalselenium.com/tips/66-blacklist
Configuration
• Use a proxy server to manipulate the traffic from your Selenium test(s)
• Identify third-party resources that are slow to load (which could negatively impact your tests)
• Blacklist them (e.g., make it so they don’t load)
Load Testinghttp://elementalselenium.com/tips/68-load-testing-revisited
Configuration
• Use a proxy server to capture the traffic from your Selenium test(s)
• Convert the HTTP Archive into a JMeter JMX file
• Run the new JMX file with JMeter to enact load on your application (modify as needed)

Broken Image Checkinghttp://elementalselenium.com/tips/67-broken-images
Forgot Passwordhttp://elementalselenium.com/tips/43-forgot-password
Configuration• Use Selenium to trigger a forgot password workflow
(to a Gmail account) and keep the browser session active
• Retrieve the e-mail and the password information via the Gmail API
• Use the password information in the active Selenium session (if applicable)
A/B Testinghttp://elementalselenium.com/tips/12-opt-out-of-ab-tests
• 3 page states available
• You can identify which state you’re in because there is different header text for each
• When you’re in the control: A/B Test Control
• For the variation: A/B Test Variation 1
• When you’re not in a test: No A/B Test
http://the-internet.herokuapp.com/abtest
Configuration
• You can easily opt-out of A/B tests by
• forging a cookie
• appending a query to the URL
• This way you get a known state of the page which isn’t likely to change without your knowledge
Workaround
• Rather than use something like AutoIt (which is a bad idea)
• You can send the file path you want to upload into the form input field (side-stepping the system dialog entirely)
Downloading a Filehttp://elementalselenium.com/tips/2-download-a-file http://elementalselenium.com/tips/8-download-a-file-revisited http://elementalselenium.com/tips/15-download-secure-files
Two approaches• Configure Selenium to download to local disk, and
delete the file when done
• Use an HTTP library, perform a HEAD request, and check the headers for the correct content type & length.
Why? • An order of magnitude faster using Selenium • No need to download the file
