TSI6223 System Testing Assignment MMU : Applying Basis Path & Testing Principles in IT Security Login Design

TSI6223: Assignment (20%)

This assignment is to be done by the students individually.

• The report should be single-spaced and use Calibri font sized 11.
• The report must have the front cover as per the appendix.
• The report should be neatly formatted.
• Due in the 10th week 10.

Part 1

Assume you are planning to set up a company that specialises in testing IT systems. As the founder of the company, from the SIX (6) testing principles covered in TS16223, which testing principle should be the focus of your company? Explain your choice thoroughly. (5m)

Part 2

Given the below pseudocode, if you are to use basis path testing (a type of white box method)...

• Isolate the user's head region.
• Get the user's face.
• Extract facial features.
• Compare features with the stored library for a match.
• If a match is > 90%, then identify the user.
• Else, display error message. Restart the process.
• Once the user is identified, ask the user for a password.
• Encrypt the keyed in password.
• Compare the encrypted password with the stored password.
• If it matches, then authenticate the user.
• Else, display error message. Restart the process.

Note: Whenever there's an error message, the login process will restart. Each user can re-try the login process a total of 3 times. If all 3 times result in failure, then the user will be prevented from logging in for 10 minutes.

• Number the pseudocode and draw the flow graph. (2m)
• Determine the cyclomatic complexity. (1m)
• Determine the basis set of linearly independent paths. (2m)
• Detail the test cases. (5m)

Part 3

Since you already used one of the white box testing methods, is it necessary to implement black box testing as well? Explain your answer in detail. (5m)
