require "./num_usage"
puts Example.new.increase(7)
"""
When I run `ruby accepts_integers.rb`
Then output should contain:
"""

"""
Scenario: Accepts floats
Given a file named "accepts_floats.rb" with:
"""ruby
require "./num_usage"
puts Example.new.increase(7.5)
"""
When I run `ruby accepts_floats.rb`
Then output should contain:
"""

"""
Scenario: Rejects other values
Given a file named "rejects_others.rb" with:
"""ruby
require "./num_usage"
puts Example.new.increase("foo")
"""
When I run `ruby rejects_others.rb`
Then output should contain:
"""
: Contract violation for argument 1 of 1: (ParamContractError)
Expected: Num,
Actual: "foo"
Value guarded in: Example::increase
With Contract: Num => Num
"""
And output should contain "num_usage.rb:8"
