# Runs ngx_pagespeed system tests.
#
# Exits with status 0 if all tests pass.
# Exits with status 1 immediately if any test fails.
# Exits with status 2 if command line args are wrong.
#
# Usage:
#   ./run_tests.sh primary_port secondary_port mod_pagespeed_dir ngx_binary
#   pagespeed_test_host
# Example:
#   ./run_tests.sh 8050 8051 /path/to/mod_pagespeed /path/to/nginx/binary
#   selfsigned.modpagespeed.com
#

# Normally we test only with the native fetcher off.  Set
# TEST_NATIVE_FETCHER=true to also test the native fetcher, set
# TEST_SERF_FETCHER=false to skip the serf fetcher.
TEST_NATIVE_FETCHER=${TEST_NATIVE_FETCHER:-false}

# Normally we actually run the tests, but you might only want us to set up nginx
# for you so you can do manual testing.  If so, set RUN_TESTS=false and this
# will exit after configuring and starting nginx.
RUN_TESTS=${RUN_TESTS:-true}

# To run tests with valgrind, set the environment variable USE_VALGRIND to
# true.
