SDD 9.2.4-5 Testing, Evaluating and Maintaining

What is the purpose of a post implementation review?

• To develop a maintenance plan

• To review user training schedules

• To discuss plans for future projects

• To evaluate the software with the client before sign-off

At which level of testing would a software developer use a driver?

• Acceptance

• Module

• Program

• System

Which of the following best describes load testing?

• Testing every function of a system

• Testing a system with large amounts of data

• Testing a system with every transaction type

• Testing of a system by different types of users

What is the purpose of a post-implementation review?

• To check that the overall system functions correctly

• To discuss the results of the acceptance testing process

• To help evaluate the new system based on client feedback

• To demonstrate the features of the new system to the client

A student designed an algorithm to determine entry costs into a show.

She correctly designed the following set of concise, thorough
and appropriate test data to test the algorithm: 2, 4, 10, 12, 20.

Which of the following algorithms is she testing?

• 
• 
• 
• 

An algorithm has been developed to check temperature.

‘Too cold’ is displayed if the temperature is below 40 degrees and

‘Too hot’ is displayed if it is 60 degrees or more.

Otherwise, the display is ‘Just right’.

The algorithm has been tested with the values 30, 50, 60 and 70.

Which other value should definitely be tested?

• 0

• 20

• 40

• 80

During which stages of the software development cycle is benchmarking relevant?

• Implementing, testing and evaluating

• Planning and designing, testing and evaluating

• Defining and understanding the problem, implementing

• Defining and understanding the problem, planning and designing

At what level of the testing process does acceptance testing occur?

• Live

• Module

• Program

• System

Why is it necessary to develop a set of criteria to evaluate a software project?

• To allow selection of an appropriate development process

• To ensure that the end users know what the software can do

• To check that the software is suitable for the intended purpose

• To enable the project managers to develop a time management schedule

Diff(a, b, result) is a subroutine that accepts two numbers as input.

It returns “yes” in result if the difference between the numbers is less than 10.

Otherwise it returns “no”.

Which of the following code fragments would be most useful

for testing the subroutine with a range of values?

• 
• 
• 
•
