Traditional mock object.
Methods return an Expectation which can be further modified by methods on Expectation.
Adds an expectation that a method identified by method_name Symbol/String must be called exactly once with any parameters. Returns the new expectation which can be further modified by methods on Expectation.
object = mock() object.expects(:method1) object.method1 # no error raised object = mock() object.expects(:method1) # error raised, because method1 not called exactly once
If method_names_vs_return_values is a Hash, an expectation will be set up for each entry using the key as method_name and value as return_value.
object = mock() object.expects(:method1 => :result1, :method2 => :result2) # exactly equivalent to object = mock() object.expects(:method1).returns(:result1) object.expects(:method2).returns(:result2)

Constrains the mock so that it can only expect or stub methods to which responder responds. The constraint is only applied at method invocation time.
A NoMethodError will be raised if the responder does not respond_to? a method invocation (even if the method has been expected or stubbed).
The mock will delegate its respond_to? method to the responder.
class Sheep def chew(grass); end def self.number_of_legs; end end sheep = mock('sheep') sheep.expects(:chew) sheep.expects(:foo) sheep.respond_to?(:chew) # => true sheep.respond_to?(:foo) # => true sheep.chew sheep.foo # no error raised sheep = mock('sheep') sheep.responds_like(Sheep.new) sheep.expects(:chew) sheep.expects(:foo) sheep.respond_to?(:chew) # => true sheep.respond_to?(:foo) # => false sheep.chew sheep.foo # => raises NoMethodError exception sheep_class = mock('sheep_class') sheep_class.responds_like(Sheep) sheep_class.stubs(:number_of_legs).returns(4) sheep_class.expects(:foo) sheep_class.respond_to?(:number_of_legs) # => true sheep_class.respond_to?(:foo) # => false assert_equal 4, sheep_class.number_of_legs sheep_class.foo # => raises NoMethodError exception

Adds an expectation that a method identified by method_name Symbol/String may be called any number of times with any parameters. Returns the new expectation which can be further modified by methods on Expectation.
object = mock() object.stubs(:method1) object.method1 object.method1 # no error raised
If method_names_vs_return_values is a Hash, an expectation will be set up for each entry using the key as method_name and value as return_value.
object = mock() object.stubs(:method1 => :result1, :method2 => :result2) # exactly equivalent to object = mock() object.stubs(:method1).returns(:result1) object.stubs(:method2).returns(:result2)
