Testing A-Level

Question 1 of 10

1. Question

Which statement best describes the purpose of testing?

To ensure that the program created will produce a profit for the company.
To ensure that the software will run as quickly as possible (as quickly as the computer hardware will allow)
To ensure that a developed program functions as it was designed and meets the needs of the end user.
To ensure that the code is written ‘as directed’ by the manager of the programming team.

2. Question

What is iterative testing?

Testing that is carried out on the whole program, at the end of development, to ensure that it meets the client/end-user requirements
Testing that is ongoing throughout development, testing the workings of sections of code, before developing the program further.
Testing that is carried out on a ‘near complete’ version of the program, which is distributed to large numbers of people, where ‘real’ users get to use the software under realistic conditions and report back to the developers any bugs / short-comings that they find.
Testing that only deals with the algorithms to make sure that they function correctly, often by tracing the change in value of variables during the execution of an algorithm, seeing if they produce expected results.
Testing that only focuses on inputs and outputs – checking that inputs are validated and result in expected outputs.
