stub/stub! will always be followed by '.and_return'

this function will aways be followed by ‘.and_return(…)’ because a stub is typically used for returning values. The required argument given to stub is a method name. When a message to this stubbed method name is received by a class or existing object of the class AND ‘.and_return’ is provided, the stub will return whatever was provided as argument to ‘.and_return’.

For example,

HomeLoan.stub!(interest_rate).and_return(‘5.5%’)

  • this will return 5.5% when a message for interest_rate in a HomeLoan class’s object is received.

HomeLoan.stub!(interest_rate).and_return(‘5.5%’, ‘3%’)

  • this will return 5.5% when a message for interest_rate in a HomeLoan class’s object is received FOR THE FIRST TIME but will return 3% for subsequent calls/messages.

Typical stub! usage

Typically you would call

my_object.stub!(:updated_at).and_return(time_object)

A stub with argument and return value

it “should use a dummy method with argument and return value” do

 dummy = mock("dummy").stub!(:emulate)
 dummy.should_receive(:emulate).with(:something).and_return("Done! sir!")
 dummy.emulate(:something).should == "Done! sir!"
end
