# Shell library to run an HTTP server for use in tests.
# Ends the test early if httpd tests should not be run,
# for example because the user has not enabled them.

# Usage:
#
#	. ./test-lib.sh
#	. "$TEST_DIRECTORY"/lib-httpd.sh
#	start_httpd
#
#	test_expect_success '...' '
#		...
#	'
#

# Can be configured using the following variables.
#
#    GIT_TEST_HTTPD              enable HTTPD tests
#    LIB_HTTPD_PATH              web server path
