Pact Ruby End to End Example

Code base to use for demonstrating features or recreating issues in the ruby implementation of pact. Please fork it and modify to demonstrate or recreate your own code.

This code base is not intended as an example of a best practice pact implementation. Its purpose is to create a running example with the simplest code possible. If you want to see an example of how you would use pact in a Ruby consumer or provider project, see the example dir in the pact repository.

Usage

Fork and clone the codebase

# Fork the repository using the 'Fork' button on the repository home page, then:
git clone [email protected]:YOUR_USERNAME/pact-ruby-e2e-example.git
cd pact-ruby-e2e-example

Set the gem versions you are using

• Open up the Gemfile and set the exact gem versions you are using. eg gem "pact", "1.12.1"

• Run bundle update

Set up consumer expectations and generate the pact

• Modify the code in consumer/spec/bar_spec.rb to recreate your consumer expectations.

• Run bundle exec rake spec to run the spec, and generate the pact file.

• You will find the pact file in consumer/spec/pacts/foo-bar.json

Verify the pact against the provider

• Modify the code in provider/bar_app.rb to recreate the response that your provider will return.

• Run bundle exec rake pact:verify:foobar to verify the pact.

To recreate issues with a local pact broker

• Set the exact gem versions in pact_broker/Gemfile and run bundle update.

• In another terminal, cd into the pact_broker directory and run bundle exec rackup.

• Follow the above instructions for setting up the consumer and provider code.

• In the root directory of this project, run bundle exec rake pact:verify:foobar_using_local_broker

To recreate issues with a remote pact broker

• In the Rakefile set the REMOTE_PACT_BROKER_BASE_URL to the value of your pact broker.

• Follow the above instructions for setting up the consumer and provider code.

• Set the PACT_BROKER_USERNAME and PACT_BROKER_PASSWORD environment variables if you are using a broker with basic auth.

  export PACT_BROKER_USERNAME=your_username
  export PACT_BROKER_PASSWORD=your_password
  

• In the root directory of this project, run bundle exec rake pact:verify:foobar_using_remote_broker

Reporting an issue

• Commit your code on a branch (so you can reuse it for other issues cleanly) and push it to your fork

  git checkout -b "foo-issue"
  git add .
  git commit -m "Modifying code to recreate my issue"
  git push --set-upstream origin foo-issue
  

• Open an issue in the appropriate codebase (see pact-foundation for most of the repositories) and include a link to your branch.
