1 # Shell library to run an HTTP server for use in tests.
2 # Ends the test early if httpd tests should not be run,
3 # for example because the user has not enabled them.
4 #
5 # Usage:
6 #
7 # . ./test-lib.sh
8 # . "$TEST_DIRECTORY"/lib-httpd.sh
9 # start_httpd
10 #
11 # test_expect_success '...' '
12 # ...
13 # '
14 #
15 # test_expect_success ...
16 #
17 # stop_httpd
18 # test_done
19 #
20 # Can be configured using the following variables.
21 #
22 # GIT_TEST_HTTPD enable HTTPD tests
23 # LIB_HTTPD_PATH web server path
24 # LIB_HTTPD_MODULE_PATH web server modules path
25 # LIB_HTTPD_PORT listening port
26 # LIB_HTTPD_DAV enable DAV
27 # LIB_HTTPD_SVN enable SVN at given location (e.g. "svn")
28 # LIB_HTTPD_SSL enable SSL
