Contract String => C::Bool
```
Background:
Given a file named "bool_usage.rb" with:
"""ruby
require "contracts"
C = Contracts
class Example
include Contracts::Core
Contract String => C::Bool
def self.strong?(password)
return if password == ""
password.length > 22
end
end
"""
Scenario: Accepts `true`
Given a file named "true.rb" with:
"""ruby
require "./bool_usage"
puts Example.strong?("verystrongandLon774gPassword!ForYouHere")
"""
When I run `ruby true.rb`
Then output should contain:
"""
true
"""
Scenario: Accepts `false`
Given a file named "false.rb" with:
"""ruby
require "./bool_usage"
puts Example.strong?("welcome")
"""
When I run `ruby false.rb`
Then output should contain:
"""
false
"""
Scenario: Rejects everything else
Given a file named "nil.rb" with:
"""ruby
require "./bool_usage"
puts Example.strong?("")
"""
When I run `ruby nil.rb`
Then output should contain:
"""
: Contract violation for return value: (ReturnContractError)
Expected: Bool,
Actual: nil
Value guarded in: Example::strong?
With Contract: String => Bool
