[gnurl] 206/264: tests: introduce preprocessed test cases


From: gnunet
Subject: [gnurl] 206/264: tests: introduce preprocessed test cases
Date: Thu, 30 Apr 2020 16:08:29 +0200

This is an automated email from the git hooks/post-receive script.

nikita pushed a commit to branch master
in repository gnurl.

commit d009bc2e565844db030d7098624b39b2903a808d
Author: Daniel Stenberg <address@hidden>
AuthorDate: Fri Apr 17 09:58:42 2020 +0200

    tests: introduce preprocessed test cases
    
    The runtests script now always performs variable replacement on the
    entire test source file before the test gets executed, and saves the
    updated version in a temporary file (log/test[num]) so that all test
    case readers/servers can use that version (if present) and thus enjoy
    the powers of test case variable substitution.
    
    This is necessary to allow complete port number freedom.
    
    Test 309 is updated to work with a non-fixed port number thanks to this.
