Using Selenium to capture screen-shots and save them to dropbox

I am going to share a small piece of code I use for screenshot capture in Selenium RC in Ruby.
First I wanted to set this up on my machine and on a mac mini that I use at work so I had to figure out a way to detect the os since the file path is different on a mac vs pc.

def is_mac?
   RUBY_PLATFORM.downcase.include?("darwin")
 end

 def is_windows?
    RUBY_PLATFORM.downcase.include?("mingw32")
 end

Code:

file_path="C:\\Users\\Leo\\Dropbox\\QA scripts\\Screenshots\\" if is_windows?
file_path="/Users/administrator/Dropbox/QA\ scripts/Screenshots/" if is_mac?

After that I wanted to make sure that the files are saved will consisst the name of the
test-case + date and time so I will know later which one is which. Here is how the magic happens.

@selenium.capture_entire_page_screenshot("#{file_path}NameOfTestCase#{Time.now.strftime("%Y-%m-%d_%H%M")}.png", '');
