Project: RSpec Mocks 2.4

Publisher: RSpec

configure any test framework to use rspec-mocks

Test frameworks that want to use rspec-mocks can use
RSpec::Mocks::setup(self) to hook into rspec-mocks. Doing so adds the
following:

To the object passed to setup:

double # creates a test double
mock   # creates a test double
stub   # creates a test double

To every object in the system:

should_receive
should_not_receive
stub

In order to give control to the consuming framework, none of these facilities
are added until RSpec::Mocks::setup(self) is called. Simply requiring
'rspec/mocks' is not sufficient.

NOTICE: the stub() method that is added to the object passed to setup is not
the same stub() method that is added to every other object.

Scenarios

RSpec::Mocks::setup(object) adds double, mock, and stub methods to the submitted object
RSpec::Mocks::setup(anything) adds methods to Object
require "rspec/mocks" does not add methods to Object

RSpec::Mocks::setup(object) adds double, mock, and stub methods to the submitted object

Given

a file named "foo.rb" with:

require 'rspec/mocks'

class CodeExample
  def init
    RSpec::Mocks::setup(self)
  end
end

example = CodeExample.new
example.init

puts example.respond_to?(:double)
puts example.respond_to?(:mock)
puts example.respond_to?(:stub)

When

I run "ruby foo.rb"

Then

the output should contain "true"

But

the output should not contain "false"

RSpec::Mocks::setup(anything) adds methods to Object

Given

a file named "foo.rb" with:

require 'rspec/mocks'

RSpec::Mocks::setup(Object.new)

obj = Object.new

puts obj.respond_to?(:should_receive)
puts obj.respond_to?(:should_not_receive)
puts obj.respond_to?(:stub)

When

I run "ruby foo.rb"

Then

the output should contain "true"

But

the output should not contain "false"

require "rspec/mocks" does not add methods to Object

Given

a file named "foo.rb" with:

require 'rspec/mocks'

obj = Object.new

puts obj.respond_to?(:should_receive)
puts obj.respond_to?(:should_not_receive)
puts obj.respond_to?(:stub)

When

I run "ruby foo.rb"

Then

the output should contain "false"

But

the output should not contain "true"
