I'm using a call to wget to download a large datafile (multiple

How can I spec the behaviour? Ideally I'd also like to not be hitting
the internet every time I test!
in my_object_spec.rb
describe ".get_data" do
before(:each) do
@my_obj = MyObject.create(@valid_attributes)
end
it "should download the file" do
# behaviour goes here
end
end
in my_object.rb:
def get_data
`wget --output-document=#{self.filename} #{self.file_uri}`
end
Use Kernel.stub!(:`, "wget..."), and use Kernel.send(:`, "wget")
instead of literal backticks.
