Class: BasicObject

Defined in:
lib/rspec/mocks/syntax.rb

Overview

The legacy :should syntax adds the following methods directly to BasicObject so that they are available off of any object. Note, however, that this syntax does not always play nice with delegate/proxy objects. We recommend you use the non-monkeypatching :expect syntax instead.

- (Object) as_null_object

Note:

This is only available when you have enabled the should syntax.

Tells the object to respond to all messages. If specific stub values are declared, they'll work as expected. If not, the receiver is returned.

    - (Object) should_receive 


  

  

    Note:
    
This is only available when you have enabled the should syntax.



  


Sets an expectation that this object should receive a message before
the end of the example.

  





  

    
Examples:

      
logger = double('logger')
thing_that_logs = ThingThatLogs.new(logger)
logger.should_receive(:log)
thing_that_logs.do_something_that_logs_a_message

    - (Object) stub 


  

  

    Note:
    
This is only available when you have enabled the should syntax.



  


Tells the object to respond to the message with the specified value.

  





  

    
Examples:

      
counter.stub(:count).and_return(37)
counter.stub(:count => 37)
counter.stub(:count) { 37 }

      - (Object) stub_chain(method1, method2) 
      - (Object) stub_chain("method1.method2") 
      - (Object) stub_chain(method1, method_to_value_hash) 


  

  

    Note:
    
This is only available when you have enabled the should syntax.



  


Stubs a chain of methods.


Warning:


Chains can be arbitrarily long, which makes it quite painless to
violate the Law of Demeter in violent ways, so you should consider any
use of stub_chain a code smell. Even though not all code smells
indicate real problems (think fluent interfaces), stub_chain still
results in brittle examples.  For example, if you write
foo.stub_chain(:bar, :baz => 37) in a spec and then the
implementation calls foo.baz.bar, the stub will not work.

  





  

    
Examples:

      
double.stub_chain("foo.bar") { :baz }
double.stub_chain(:foo, :bar => :baz)
double.stub_chain(:foo, :bar) { :baz }
  # Given any of ^^ these three forms ^^:
  double.foo.bar # => :baz

  # Common use in Rails/ActiveRecord:
  Article.stub_chain("recent.published") { [Article.new] }

    - (Object) unstub 


  

  

    Note:
    
This is only available when you have enabled the should syntax.



  


Removes a stub. On a double, the object will no longer respond to
message. On a real object, the original method (if it exists) is
restored.


This is rarely used, but can be useful when a stub is set up during a
shared before hook for the common case, but you want to replace it
for a special case.
