    Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 6
    § Independent – loosely coupled with one another
    § Negotiable – Stories are what and why , not how ( 99% ).
    § Valuable – for the customer!
    § Estimatable – Effort/Cost of design, build, and test.
    § Small (sized appropriately)
    § Testable – pass or fail
    INVEST in good requirements

    § Students and Staff members can request the Library to notify him/her when a Book becomes
    available.
    § Also, they can reserve the book. Before reserving a Book for someone the Library check, for
    students, with the Registrar, if the Student is currently enrolled, and for employees, with Human
    Resources if the employee has an active contract.

  20. jgs
    Javier Gonzalez-Sanchez | CSC 309 | Winter 2023 | 20
    Given a Date class with the following methods:
    opublic Date(int year, int month, int day)
    opublic Date() // today
    opublic int getDay(), getMonth(), getYear()
    opublic void addDays(int days) // advances by days
    opublic int daysInMonth()
    opublic String dayOfWeek() // e.g. "Sunday"
    opublic boolean equals(Object o)
    opublic boolean isLeapYear()
    opublic void nextDay() // advances by 1 day
    opublic String toString()
    § Come up with unit tests to check the following:
    oThat no Date object can ever get into an invalid state.
    oThat the addDays method works properly.
    • It should be efficient enough to add 1,000,000 days in a call.
