Introduction to Lua-Land CPU Flame Graphs
We have uploaded Test::Nginx 0.27 to CPAN:
It will appear on the CPAN mirror near you in the next few hours or so. After that, you can install the module like below
sudo cpan Test::Nginx
or better, when you have the App::cpanminus module already installed:
sudo cpanm Test::Nginx
Special thanks go to all our contributors and developers!
Here's the complete change log for this release (compared to the last CPAN release, 0.26):
feature: added the --- reload_fails new section to skip checking config_version after HUP reload in the HUp reload testing mode.
feature: added a "--- gen_dgram_request" section.
feature: relaxed the Server response header parsing pattern for extracting the nginx core verison number.
bugfix: when --- reload_fails is specified, we did not assume --- no_chck_leak since it would always fail in the check leak testing mode.
feature: implemented the
--- shutdown_error_logsection for checking the error logs generated during nginx exit.
feature: added new test mode enabled by the env TEST_NGINX_USE_HTTP2=1 and new section "--- http2", for enabling the HTTP/2 protocol to send the test request.
bugfix: when TEST_NGINX_USE_STAP=1 env was specified, the master process would be turned off when for test blocks without actually using --- stap.
feature: be more patient to wait for the nginx to start up in profiling and "check leak" test mode.
optimize: use perl's own remove_tree() instead of the shell command 'rm -rf' since the latter may use too much memory.
feature: added support for the env TEST_NGINX_CHECK_LEAK_COUNT to control how many data points to sample in the "check leak" test mode.
feature: now we pass through the MOCKNOEAGAIN_VERBOSE and MOCKNOEAGAIN env to the nginx worker processes by default as well.
feature: added support for TEST_NGINX_WORKER_USER env for setting the user account (and user group) for nginx worker processes; defaults to root when the master is run by root.
bugfix: the value of env TEST_NGINX_WORKER_USER did not accept a single user name (without a user group name).
feature: added support for the --- access_log section for checking access log file content.
bugfix: valgrind test mode: we no longer disable nginx master process in this mode.
bugfix: we did not clean up nginx's *_cache directories under the server root directory.
feature: added support for environment variable TEST_NGINX_REUSE_PORT for enabling the reuseport parameter in the listen directive automatically generated in nginx.conf.
feature: we now check for the new "write guard" warning message to detect misuses of lua globals.
feature: added the use_hup() Perl utility function.
feature: when --- no_error_log fails, we output up to 9 lines of subsequent error log messages for better debuggability (for example, wen can have complete lua backtraces).
feature: expanded environment values in --- user_files section.
bugfix: when setting TEST_NGINX_USE_HUP=1, some directories could not be cleaned up correctly.
feature: implemented the TEST_NGINX_USE_RR=1 env for enabling Mozilla rr to record the nginx server execution.
bugfix: increased resiliency in HUP reload mode.
feature: added the '--- skip_openssl' section to skip tests depending on the OpenSSL version NGINX was built with.
bugfix: ensured we do not remove some files when using HUP mode.
bugfix: properly use a concat operator instead of a range.
bugfix: ensure servroot is cleaned up when starting NGINX for the first time.
This Perl module provides a test scaffold for automated testing in Nginx C module or OpenResty-based Lua library development.
This class inherits from
Test::Base, thus bringing all its declarative
power to the Nginx C module testing practices.
All of our OpenResty projects are using this test scaffold for automated regression testing.
Please check out the full documentation on CPAN:
as well as the official user guide in the book "Programming OpenResty":
All of our Nginx modules (as well as our lua-resty-* libraries) are using Test::Nginx to drive their test suites. And it is also driving my test cluster running on Amazon EC2:
Please note that this module is completely different from the Test::Nginx module originally created by Maxim Dounin.
