$ gem build sift.gemspec
$ gem push sift-<current version>.gem

$ bundle
$ rake -T
$ rake build
$ rake install
$ rake release

Testing

To run the various tests use the rake command as follows:

$ rake spec

Integration testing app

For testing the app with real calls it is possible to run the integration testing app, it makes calls to almost all our public endpoints to make sure the library integrates well. At the moment, the app is run on every merge to master

How to run it locally

  1. Add env variable ACCOUNT_ID with the valid account id
  2. Add env variable API_KEY with the valid Api Key associated from the account
  3. Run the following under the project root folder
# Install the budle locally
bundle check || bundle install
# Run the app
bundle exec ruby test_integration_app/main.rb
