If the tests don't work, make sure +that you have up to date versions of each of these perl modules: +- HTTP::DAV (DAV tests) +- DateTime (mod_include tests) +- Time::HiRes +- Protocol::HTTP2::Client and AnyEvent (mod_http2 tests) +- Test +- Test::Harness +- Crypt::SSLeay +- Net::SSLeay +- IO::Socket::SSL +- IO::Socket::IP +- IO::Select +- LWP::Protocol::https + +Quick Start +----------- + +If you don't care how it works and just want to run the tests, here's +how you go about doing that. + +1. You need an installation of Apache. (1.3.x thru trunk) +2. Any DSOs you wish to use should be configured in that Apache's + httpd.conf (the test harness will pick this configuration up) +3. Setup: + perl Makefile.PL -apxs /path/to/apache/bin/apxs +4. Run the tests: + t/TEST +5. Evaluate test output. + +Getting a little deeper +----------------------- + +The test harness will run every .t file under the t/ directory. So +let's say you only want to run the tests for PHP. Do this: + t/TEST -httpd /path/to/apache/bin/httpd t/php + +That will start the test server, run the .t tests under t/php and shut +down the test server. You can also control each of these steps. + +This will start the test server: + t/TEST -httpd /path/to/apache/bin/httpd -start + +This will run the PHP tests in the test environment: + t/TEST t/php + +This will stop the test server: + t/TEST -stop + +This will run the server under gdb (using -X): + t/TEST -d gdb + +Note: At this point, you have a working test environment. You can +look in t/conf for the test server configuration files. These are +generated by the test harness. Once you have a working test +environment, you do not need to specify 'httpd' on the t/TEST command +line. For instance, to start the server up again, the command + t/TEST -start +would be sufficient. + +Running Regression Tests +------------------------ +For a full regression test, you should have all modules loaded. Build the server +with + configure --enable-modules=reallyall --enable-load-all-modules ... +among other things. Edit the generated httpd.conf and comment all mpm modules +that you do not want. Run "t/TEST -clean" again. + +You will see some + skipped: cannot find module 'XXX' +as not all modules are in every apache release (but the tests run for all). + +All in all, some >4k tests will run and the result needs to be: PASS + +Trouble Shooting +---------------- +If you have a "PASS" at the end of "t/TEST", congratulations! If not, this +sections gives some advise in order to find the cause. Feel free to expand +this to make life easier for others. + +0. If your test startup hangs forever in "waiting for server to warm up", but + the test server is reachable under port 8529, you might be the victim of + ipv4/6 confusion. The default servername configured is "localhost" and + some operating systems define 127.0.0.1 *as well as* ::1 in /etc/hosts. + If the test server listens only on 0.0.0.0 it might not answer requests to + ::1 and that causes the test startup to hang. + Solution: comment the ::1 line in /etc/hosts and see if that improves matters. +1. Run "t/TEST -clean" every time you change something in your Apache + configuration. The test suite picks up certain things from your installed + httpd.conf (such as LoadModule statements) and will not see your changes + unless you clean it. +2. Failures in proxy.t may originate from the fact that the test script cannot + open the specified port. This happens on some machines if you abort a test + run and the socket is not properly shut down. Check if the error goes + away after a reboot. (proxy.t tests are slow, so chances you interrupt tests + at that point are good.) +3. Failures in access.t may result from reverse lookups not working or giving + other answers than expected. In the cause 0 above, if the test client + connects via 127.0.0.1, a "Grant for localhost" might resolve to "::1" + and therefore will not match the access rules of the tests. + Solution: check that your servername is 'localhost' (which is + the default) and that it *always* resolves to 127.0.0.1. +4. If some ssl test cases fail, especially when t/ssl/proxy.t fails, the + reason can be mismatches between your installed SSL library and the one + httpd uses. The "openssl" binary found in your $PATH is used to create + binary setup files by t/TEST. If another version of openssl then tries + to read these from your Apache server process, it might fail. + Try the following: + > t/TEST -clean + > PATH=<bin dir of correct openssl>:$PATH t/TEST + If a lot of ssl tests fail, check in the error log for the presence of + a certificate validation error. If you find it, check the expiration date + of the TLS/SSL certificates used by the tests, they might be expired. + Running TEST -clean should delete the old ssl certificates, so they'll be + regenerated during the next run. +5. If you see failures in the modules/h2.t test cases, please notify the dev + mailing list with a description of your setup. These tests are quite young, + currently only valid in 2.4.x and later and interact with quite some other + modules as well as Openssl versions installed. Some tests require mod_ssl + so make sure to load it in the httpd conf. +6. Segmentation faults and core dumps occurring while executing the test suite + might indicate a real problem but always run again the tests after + a clean make install to avoid inconsistencies from old objects. +7. If you see error messages like "Parse errors: Bad plan. + You planned X tests but ran Y." it usually means that you are missing + a perl module or the tested httpd module depends on another one + not loaded in the httpd config. +8. If you see SSL certificate errors, remove t/conf/ssl/ca prior to + t/TEST -clean +9. perl 5.28 in MacOS homebrew seems to hang the test suite. Invoking + /usr/bin/perl Makefile.PL -apxs ... will cause an older perl to be used. + +Smoking Tests +------------- + +Sometimes it's possible that the test is passing properly for the +first time, when it's run for the first time in the thread. But when +you run it again, the test might fail. It's important to run the +repetition smoke testing. For example to repeat the tests 5 times you +can run: + + t/SMOKE -times=5 + +It's also possible that a test will pass when it's run after a +particular test, but if moved to run after a different state it may +fail. For this reason by default the tests run in random order. + +Since it's important to be able to reproduce the problem with the +random testing, whenever -order=random is used, the used seed is +printed to STDERR. Which can be then fed into the future tests with: +via APACHE_TEST_SEED environment variable. + +By adding the option -order=repeat, the tests will be run in +alphabetical order. + +Combining these two important smoke testing techniques, one can run +tests with: + + t/SMOKE -times=N -order=(repeat|random) + +For example, to run the mod_rewrite tests 5 times, one would: + + t/SMOKE -times=5 -verbose t/modules/rewrite.t + +So the tests can be repeated N times, and run in the following three +modes: + +- randomize all tests +- repeat the whole tests suite N times + +For configuration options and default settings run: + + t/SMOKE -help + +For more information refer to the Apache::TestSmoke manpage. + + +Test Environment Configuration +------------------------------ + +The test server is configured with conf files like any normal Apache +server. The tricky part is those conf files are generated by the +harness just prior to starting the server. t/conf/httpd.conf is +generated by t/conf/httpd.conf.in. If that does not exist, the +harness will generate a working configuration and will include +LoadModule (and AddModule for Apache 1.3) directives from the +httpd.conf associated with the httpd binary you are using for testing. +If t/conf/extra.conf.in exists, t/conf/extra.conf will be generated +from that, and an Include directive for that file will be put in the +generated t/conf/httpd.conf. t/conf/apache_test_config.pm is +generated from the test configuration. It contains all the +information about the configuration of your test server. You can +access this information in test scripts by: + my $env = Apache::TestConfig->thaw; +Apache::TestConfig access apache_test_config.pm and returns a hash +reference with all the information. Look through +apache_test_config.pm, it's a lot of stuff. Once these conf files are +generated, you have a working test environment, and they must be +'cleaned' if you wish to make changes to them. To clean the +environment: + t/TEST -clean +(Now you will have to specify your httpd binary when starting back up +again.) + + +More Information +---------------- + +For more information on using the test harness and writing tests, see +the README in Apache-Test and the examples in Apache-Test/t. + +The test harness was originally written by Doug MacEachern and is +discussed on the httpd dev mailing list (dev@httpd.apache.org). + +It is also included in modperl-2.0 source along with tests for +modperl-2.0. |
