   1# Shell library to run git-daemon in tests.  Ends the test early if
   2# GIT_TEST_GIT_DAEMON is not set.
   3#
   4# Usage:
   5#
   6#       . ./test-lib.sh
   7#       . "$TEST_DIRECTORY"/lib-git-daemon.sh
   8#       start_git_daemon
   9#
  10#       test_expect_success '...' '
  11#               ...
  12#       '

  14#       test_expect_success ...
