Ruby code for configuring Selenium to access JavaScript console

Question

What is the correct Ruby code for configuring Selenium to access the JavaScript console (i.e., messages writing using console.log, console.error, console.info, etc.)?

I've found several articles with Java, Python, and C# code; but, I'm having trouble getting everything just right for Ruby.

Here is my best guess for Firefox:

  caps = Selenium::WebDriver::Remote::Capabilities.chrome
  caps[:loggingPref] = {:browser => :all}
  return Selenium::WebDriver.for :firefox, :desired_capabilities => caps

This code doesn't appear to affect anything (I get some logging messages, but not those generated by console.log, console.error, etc.). Therefore, I suspect I just have something spelled wrong, or a symbol where I need a string.

Chrome to provide access to console.info, console.error, and console.warn messages by default. It does not show console.log messages. I assume there is a similar technique for configuring the Chrome driver to return all messages; but, again, I can't find just the right combination of keys, values, symbols, and strings to make it work.

The capability is called :logging_prefs in ruby and the :browser parameter is a string value.

Here's the code (you were quite close!):

caps = Selenium::WebDriver::Remote::Capabilities.firefox
caps[:logging_prefs] = {:browser => "ALL"}
return Selenium::WebDriver.for :firefox, :desired_capabilities => caps

Then you can get the log messages with driver.manage.logs.get(:browser)
