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.
