Help: File Size defining with Cucumber Watir.


I am working for automation with Cucumber and watir in a software company.

I have a problem while working windows component for uploading I need to do the following:

Given /^I have selected a logo “([^”]*)" of size (\d+) MB$/ do |arg1, arg2|

** browser.file_field(:name, “file”).set(arg1)**


But, I am having problem to get to the file size to pass this test. I need to compare the file size with the given size.

Anybody, please help me as soon as possible.
