Feature: attribute of subject
Scenario: specify value of a nested attribute
Given a file named "example_spec.rb" with:
"""ruby
class Person
attr_reader :phone_numbers
def initialize
@phone_numbers = []
end
end
RSpec.describe Person do
context "with one phone number (555-1212)"do

person.phone_numbers << "555-1212"
person
end
its("phone_numbers.first") { is_expected.to eq("555-1212") }

"""
When I run rspec with the documentation option
Then the output should contain:
"""

phone_numbers.first
is expected to eq "555-1212"
"""
Scenario: specify value of an attribute of a hash
Given a file named "example_spec.rb" with:
"""ruby
RSpec.describe Hash do
context "with two items" do
subject do
{:one => 'one', :two => 'two'}
end
its(:size) { is_expected.to eq(2) }

When I run rspec
Then the examples should all pass
Scenario: specify value for key in a hash

When I run rspec

When I run rspec
Then the output should contain "Failure/Error: its(:size) { is_expected.to_not eq(0) }"
And the output should not match /#[^\n]*rspec[\x2f]its/
Scenario: examples can be specified by exact line number
Given a file named "example_spec.rb" with:
"""ruby
RSpec.describe Array do
context "when first created" do
its(:size) { is_expected.to eq(0) }
end

"""
When I run rspec specifying line number 3
Then the examples should all pass
Scenario: examples can be specified by line number within containing block

"""ruby

When I run rspec specifying line number 2

RSpec.describe Klass do
subject(:klass) { Klass.new }
its(:foo) { will_not raise_error }

"""ruby

And the output should contain "Failure/Error: its(:foo) { will_not raise_error }"
And the output should match /expected no Exception, got #<NoMethodError: undefined method [`']foo'/
Scenario: examples will warn when using non block expectations
Given a file named "example_spec.rb" with:
"""ruby
class Klass
def terminator
"back"

end
RSpec.describe Klass do
subject(:arnie) { Klass.new }

Then the example should fail
And the output should contain "ArgumentError:" and "`will` only supports block expectations"
