Instance Method Details

#as_null_object ⇒ 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.

    #should_not_receive  ⇒ Object

during this example.

    #should_receive  ⇒ Object 


  

  

    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

    #stub  ⇒ Object 


  

  

    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 }

      #stub_chain(method1, method2)  ⇒ Object 
      #stub_chain("method1.method2")  ⇒ Object 
      #stub_chain(method1, method_to_value_hash)  ⇒ Object

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] }

    #unstub  ⇒ Object 


  

  

    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.
