Instance Method Summary

Instance Method Details

#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.

#null_object?

Note:

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

Returns true if this object has received #as_null_object

#should_not_receive

Sets and expectation that this object should not receive a message during this example.

#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

#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 }

#stub_chain(method1, method2) #stub_chain("method1.method2") #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] }

#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.
