7.3 Development and testing Part 2

What is the purpose of testing a system?

• To create the system

• To develop the system

• To ensure it is functioning correctly

• To design the system

What is the difference between unit testing and whole-system testing?

• Unit testing tests individual parts, while whole-system testing tests the entire system

• Unit testing is for hardware, while whole-system testing is for software

• Unit testing is for small systems, while whole-system testing is for large systems

• Unit testing is for software, while whole-system testing is for hardware

What should a good test plan include for every system module?

• The expected outcome of the test

• The name of the programmer

• The cost of the system

• The date of system delivery

What type of data should a test plan always use?

• Normal, extreme, abnormal, and live data

• Abnormal data only

• Extreme data only

• Normal data only

What is the purpose of using extreme data in testing?

• To test data that should be rejected

• To test data on the border of what the system will accept

• To test data that should be accepted without any problems

• To test the system before delivery

What should be tested to make sure that tables hold data correctly?

• Output screens

• Data structures

• Validation rules

• Input screens

What should be tested to make sure that system errors are rejected?

• Input screens

• Validation rules

• Data structures

• Output screens

What should be tested to make sure that data can be entered correctly?

• Validation rules

• Output screens

• Data structures

• Input screens

What should be tested to make sure that results are correct?

• Validation rules

• Data structures

• Input screens

• Output screens

What is the purpose of integrated systems testing?

• To test data that should be accepted without any problems

• To test the system before delivery

• To test the system as a whole, across the entire organisation

• To test individual parts of the system
