I'm trying to stub(!) the Kernel.` (backquote) method and I'm having
confusing (to me) results. Here's the method I'm spec'ing:
class Barcode
...
def raw_barcodes
self.make_temporary_copy
`OcrBarcode #{self.temp_file_path}`
end
...
end
And this is my (newbish) attempt at the spec:
describe "Calling @barcode.raw_barcodes" do
before(:each) do
File.stub!(:exist?).and_return(true)
@barcode = Barcode.new('path/to/valid.pdf')
Kernel.stub!('`'.to_sym)
end
it "should make a copy of the file" do
@barcode.should_receive(:make_temporary_copy)
@barcode.raw_barcodes
end
it "should make a system call to OcrBarcode"
it "should make the system call to OcrBarcode passing in the
temporary copy of the file"
it "should create foo.pdf.barcode"
end
When I run this (using cmd-d in the TM bundle), the test passes, but I
get this line injected about the green "should make a copy of the
file":
/Users/george/work/simplify_md/vendor/plugins/rspec/lib/spec/mocks/proxy.rb:129:
command not found: OcrBarcode
/Users/george/work/simplify_md/tmp/valid_2007_10_24_111354_EDT.pdf
(all one line)
Significantly, if I remove the stub (Kernel.stub!('`'.to_sym)), I get
the same result: passing with the same "command not found" message.
Is there an accepted way to stub subshell calls?
Thanks,
/g
