MockingComponents

This section covers the specifics of setting up an application using the sinatra_more generators and each mocking component.

Mocha

To use mocha, you must first install the gem:

$ sudo gem install mocha --source http://gemcutter.org

Now, you can invoke the generator:

$ sinatra_gen demo_app . -m mocha

You are now able to use mocha to mock and stub within your tests. To mock simply use:

SomeClass.expects(:some_class_method).times(2).returns(true)
SomeClass.any_instance.expects(:some_method).times(2).returns(true)

and to stub an object:

SomeClass.stubs(:some_class_method).returns(false)

or create a stub from scratch:

object = stub(:hello => "demo")
object.hello # => "demo"

RR

To use rr, you must first install the gem:

$ sudo gem install rr --source http://gemcutter.org

Now, you can invoke the generator:

$ sinatra_gen demo_app . -m rr

You are now able to use rr to mock and stub within your tests. To mock simply use:

mock(SomeClass).some_class_method { true }
mock.instance_of(SomeClass).some_method {false}

and to stub an object:

stub(SomeClass).some_class_method { false }

or create a stub from scratch:

object = Object.new
stub(object).hello { "demo" }
object.hello # => "demo"
