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
28# LIB_HTTPD_SSL enable SSL
