Passing multiple files to input node with Watir (using Ruby)

Question

So I have hit a bit of a snag. I am trying to automate a test case where I need to pass multiple files to an input node and I cannot figure out how to do so. I can use either

Answer 1

Currently there doesn't seem to be a workaround for Firefox. If anybody knows of one, please post the answer as I couldn't find a solution anywhere. I figured I'd post the solution for Chrome here because resources are scarce on this.

If you need to test for multiple file uploads, have that particular instance load the Chrome driver with:

@browser = Watir::Browser.new :chrome, :prefs => profile

Then you're going to want to pass it a string that looks something like this:

paths = "path/to/first/file.json\npath/to/second/file.json\n...etc
file_field.send_keys paths
