Chapter 2 Testing throughout the software life cycle

What are the good practices for testing within the development life cycle?

• Early test analysis and design.

• Different test levels are defined with specific objectives.

• Testers will start to get involved as soon as coding is done.

• A and B above.

Which option best describes objectives for test levels with a life cycle model?

• Objectives should be generic for any test level.

• Objectives are the same for each test level.

• The objectives of a test level don't need to be defined in advance.

• Each level has objectives specific to that level.

Which of the following is a test type?

• Component testing

• Functional testing

• System testing

• Acceptance testing

Which of the following is a non-functional quality characteristic?

• Feasibility

• Usability

• Maintenance

• Regression

Which of these is a functional test?

• Measuring response time on an on-line booking system.

• Checking the effect of high volumes of traffic in a call-center system.

• Checking the on-line bookings screen information and the database contents against the information on the letter to the customers.

• Checking how easy the system is to use.

A regression test:

• Is only run once.

• Will always be automated.

• Will check unchanged areas of the software to see if they have been affected.

• Will check changed areas of the software to see if they have been affected.

Non-functional testing includes:

• Testing to see where the system does not function correctly.

• Testing the quality attributes of the system including reliability and usability.

• Gaining user approval for the system.

• Testing a system feature using only the software required for that function.

Beta testing is:

• Performed by customers at their own site

• Performed by customers at their software developer's site

• Performed by an independent test team

• Useful to test bespoke software or Useful to test software developed for a specific customer or user.
