How do I test any open source tool (say autoconf) after I build from source on a new architecture. I want to validate the binaries before packaging them for the new platform. All sources do not come with the test cases. So is it correct to assume I have to either write my own test cases or contact the maintainer? If I start writing test cases, I have a lot to worry about coverage of these tests.. Is there a testcase repository or something for all open source software?
