Black box testing Dbc Design by contract

Price: $5 USD

Question description

Imagine an operation is specified as follows:

context: Customer::compareDetails(otherName : String, otherAddressDetails : AddressDetails)


-- otherName and otherAddressDetails are not null


-- if the name of this object matches otherName and the addressDetails of this object matches otherAddressDetails

-- return true

-- otherwise return false

Suppose you are asked to design black-box tests for this operation and are allowed to use only six different tests. Say what tests you would choose. For each test provide the inputs, the expected result, and a brief rationale for the test. Assume design by contract.
