I'd like to export Testopia test cases in CSV or XML format but the builtin export doesn't allow to have the full test case with steps and results. I have to export for someone who will do tests without an Internet connection.
You should be able to locate the cgi file, tr_show_case.cgi in the testopia patch bugzilla directory. You could probably export the related format using the link below. With the last link, you should be able to export out a printable format including full test case with steps and expected results.
