This project does not use GitHub issues for questions, investigations, discussions, and so on. Issues are appropriate for something specific enough for a maintainer or contributor to work on:
- There should be enough information to reproduce the behavior observed in a reasonable amount of time
- It should be reasonably clear why the behavior should be changed and why this cannot or should not be addressed in application code, a separate library and so on
All issues that do not satisfy the above properties belong to the Ruby RabbitMQ clients mailing list. Pull request that do not satisfy them have a high chance of being closed.
Please read the sections below to get an idea about how to run Bunny test suites first. Successfully
running all tests, at least with CI environment variable exported to true, is an important
first step for any contributor.
Once you have a passing test suite, create a branch and make your changes on it. When you are done with your changes and all tests pass, write a good, detailed commit message submit a pull request on GitHub.
The project uses Bundler for dependency management and requires RabbitMQ 3.5+ to be running
locally with the rabbitmq-management and rabbitmq_consistent_hash_exchange plugins enabled.
The specs require RabbitMQ to be running locally with a specific set of virtual hosts
and users. RabbitMQ can be provisioned and started any way that's convenient to you
as long as it has a suitable TLS keys configuration and management plugin enabled.
Make sure you have a recent version of RabbitMQ (> 3.7.10).
The test suite can either use a locally available RabbitMQ node (generic binary builds are an option that works well) or by running a RabbitMQ server in a Docker container.
It is possible to start a local RabbitMQ node from the repository root. It is not necessarily optimal but can be a good starting point but is a useful example:
RABBITMQ_NODENAME=bunny RABBITMQ_CONFIG_FILE=./spec/config/rabbitmq.conf RABBITMQ_ENABLED_PLUGINS_FILE=./spec/config/enabled_plugins rabbitmq-server
The specs need the RabbitMQ management plugin to be enabled and include TLS connectivity tests,
so the node must be configured to use a certificate and key pair.
The config and enabled plugin files in the spec/config directory take care of that
but certificates must be provisioned locally. By default there's a set of CA, server, and client certificates pre-generated at spec/tls.
The BUNNY_CERTIFICATE_DIR environment variable can be used to a directory containing a CA certificate
and a certificate/key pair to be used by the server. The directory can be generated using
tls-gen's basic profile. This option is recommended.
BUNNY_RABBITMQ_HOSTNAME can be used to override the expected server hostname for peer verification in the TLS test suite:
BUNNY_CERTIFICATE_DIR="/path/to/tls-gen/basic/result" BUNNY_RABBITMQ_HOSTNAME="mayflower" bundle exec rspec
Certificates can be generated with tls-gen's basic profile.
In that case they include a Subject Alternative Name of localhost for improved portability.
There is also a script that preconfigured the node for Bunny tests. It is sufficient to run it once but if RabbitMQ is reset it has to be executed again:
RABBITMQ_NODENAME=bunny ./bin/ci/before_build
The script uses rabbitmqctl and rabbitmq-plugins
to set up RabbitMQ in a way that Bunny test suites expect. Two environment variables,
RABBITMQCTL and RABBITMQ_PLUGINS, are available to control what rabbitmqctl and
rabbitmq-plugins commands will be used. By default they are taken from PATH
and prefixed with sudo.
And then run the core integration suite:
RABBITMQ_NODENAME=bunny CI=true rspec
First off you have to install Docker Compose (and by proxy Docker). Version >= 1.6.0+ is required for compose version 2 syntax.
After those have been installed (and the docker-compose command is available on your command line path), run
docker-compose build && docker-compose run --service-ports rabbitmq
The first time you do this, it will take some time, since it has to download everything it needs to build the Docker image.
The RabbitMQ server will run in the foreground in the terminal where you started it. You can stop
it by pressing CTRL+C. If you want to run it in the background, pass -d to docker-compose.
If Toxiproxy is running locally on standard ports or started via Docker:
docker-compose run --service-ports toxiproxy
then Bunny will run additional resiliency tests.
Prior to running the tests, configure the RabbitMQ permissions by running ./bin/ci/before_build
if you have RabbitMQ locally installed, if you are running RabbitMQ via Docker as above this step
is not required as the setup is baked in.
Make sure you have those two installed and then run integration tests:
bundle install
rake integration
It is possible to run all tests:
bundle exec rspec
It is possible to run only integration and regression tests but exclude unit and stress tests:
CI=true bundle exec rspec spec/higher_level_api/ spec/lower_level_api spec/issues spec/higher_level_api/integration/connection_recovery_spec.rb
