Automatic contract verification for your RSpec suite

• Rspec 3.0.0.beta2

Install the rspec-contracts gem alongside rspec in your gemfile.

group :development, :test do
  gem "rspec", "3.0.0.beta2"
  gem "rspec-contracts"
end

Then update your bundle.

$ bundle

Define doubles using contract_double, providing the contract name as the first argument.

user = contract_double(:user, email: "me@example.com")

Running the specs will then show a summary of unverified contracts.

$ rspec
