The tests have been created in Windows. To run them under Linux, you need to search&replace all \r\n with \n.
This is also an issue, which makes it hard to run our tests on multiple platforms.
As we have only Windows version of AUT, let us just investigate where \r\n is mentioned in the script and how we can avoid this. As far as I remember we were performing some line endings normalizing, so there should not be any mention of \r ideally
