Taking Screenshots In Selenium Using Ruby

13 Oct 2010

I LOVE being able to take screenshots of my Selenium tests as they are running!

Here’s how I take screenshots of my selenium tests running, written in Ruby:

Find the variable referencing the selenium driver. Might look something like this: <pre lang="ruby">@selenium_driver = Selenium::Client::Driver.new(…..</pre>
Wait for condition to take screenshot. Example: <pre lang="ruby">page.wait_for_element(“//h1”, {:timeout_in_seconds => 10})</pre>
Take screenshot. Example: <pre lang="ruby">@selenium_driver.capture_entire_page_screenshot(File.expand_path(File.dirname(FILE)) + ‘screenshot1.png’, ‘’)</pre>

or something simpler like:
```
@selenium_driver.capture_entire_page_screenshot('~/Desktop/screenshot1.png', '')
```

Selenium documentation for using the capture screenshot function.
