Question

Select an Object-Oriented software application, as well as a Sequential software application. Develop a testing template and create five meaningful test cases for each.

Answer 1

Testing Object Oriented Software Application:

Testing object-oriented software application usually done testing the underlying classes in the application. Class testing, testing the behaviour of the class and the methods that perform the logic, creation of objects by testing the constructors, state of the object by testing the variables etc. Object methods encapsulate the business logic in object-oriented application.

Consider Banking application which has the classes like

Bank class

Account - Abstract class.,

id , name , balance

getters and setters for variables.

methods like withdraw() , deposit() , viewBalance(), calculateInterest()

SavingAccount the child class of Account.

interestRate

overridden method - calculateInterest() methods

CheckingAccount the child class of Account.

interestRate

overridden method - calculateInterest() methods

Testcases:

Try to create an object of Account. Abstract class should not create any objects.

Creation of objects for SavingAccount , Checking Account.

Testing for methods setters and getters for the variables like balance.

Test business logic for calculate interest for

Saving account class

Checking account class.

Test for deposit and withdraw business logic.

Steps:

Create an object for Saving account.

Invoke calculateInterest() method.

Calculate the amount as per the business logic.

Assert for object returned value and as per business logic.

---------------------

Testing Sequential Software Application

Unlike object oriented applications,, sequential applications do not have classes and objects.

They perform all the business logic in a program with functions and modules.

Consider a console application written in C language that

ask user to choose from menu of options and performs the tasks as per the user selection.

TestCases.

Test for Program Features:

Test program features and function interactions.

Positive testcase

Test the individual functions business logic what the method is intended to perform.

Negative testcase:

Test the individual functions business logic what the method is NOT intended to perform.

Static testcase:

Test the readability of the sequential software program like code readability, comments,

code indentation etc.

Compatibility Test Case:

Test the program executable by building and running on different OS versions

for example, like Windows 7, Windows 10 etc.
