Question

Part 1: Software Testing (6 marks):

Assume that you are building a web-based grocery shopping system (similar to the ones that

Woolworths and Coles provide). The system allows customers to add grocery items to a (virtual)

shopping cart and pay online. They will then be notified when the order is ready for pick-up in the

selected store.

1. Identify one functional and one non-functional requirement related to that system (2 marks).

2. Describe how you would test those two requirements (2 marks).

3. For the item counts in the shopping cart, describe what equivalence classes and boundary values

you would choose when creating the corresponding unit tests (2 marks).

Part 2: Project Management (Risk Management) (6 marks):

Consider the scenario outlined in Part 1.

1. Identify two risks associated with the development of that system (2 marks).

2. Assess their probability and severity (2 marks).

3. Provide strategies to manage the risks (2 marks).

Part 3: Project Planning (3 marks):

Image you were the project manager for the system outlined in Part 1 in an early stage of the project.

1. Identify a possible milestone together with a related deliverable (1 mark).

2. Describe how you would break down the milestone into at least two different tasks (see table on

slide 75 of the Project Management and Planning lecture for an example) (2 marks).

Answer 1

Part 1:

1. The functional requirement is as follows-

The user should be able to search the products available currently in the nearby stores and should be able to order the specified amount of quantity from the product catalog.

The nonfunctional requirements is as follows-

The website should be able to able to handle more than 10000 users without affecting it's performance.

2. For the functional requirement-

a)Search based on the item name, brand name or something more broadly.

b)Check different sort options.

c) Search results have to be relevant.

d) How many results to display per page, test the page navigation and mechanism.

For the nonfunctional requirement-

We will perform load testing to check the performance of the website under real life situations-

a) Check the response time for each transaction.

b) Performance of system components under various loads.

c) Performance of database components under various loads.

d) Latency between client and server.

3. Boundary values for the shopping cart item count can be defined as follows-

0 - Invalid

1 -Valid

Maximum number of items in the cart- Valid

Maximum number of items in the cart+1 - Invalid

For equivalence class testing-

We have three classes-

Integers<1 -Invalid Input

Integers>=1 and <=Max Items - Valid Input

Integers>Max items allowed - Invalid Input

Part 3-

The milestone for the project can be "Scoping Complete" which implies that all the stakeholders have been properly consulted and initial requirement gathering phase is over. The deliverable associated with this milestone can be an SRS(Software Requirement Specification) document.

The milestone can be broken down into two tasks-

1. Define context and Model requirements- To define the boundaries and interfaces of the proposed system with the external world, define the entities which interact with our proposed system and then represent the requirements in an acceptable format which may help us remove inconsistency and wrong requirements.

2. Finalize the requirements- After the first step, we have a better understanding of the system, the inconsistency has been removed, now we analyzed the finalized requirements and final step is to document this properly.
