05 - Practice Test

 1. A test plan only needs to take the user down one possible path of the program and use 'normal' data.

  FALSE

  TRUE

 2. Final testing is generally a much quicker process than iterative testing.

  True

  False

 3. Erroneous test data contains values that the program should not accept, e.g.

  '#' in an 'age' field

  none of these options

  'John' entered in a name field

  the number '4' in an age field

 4. In _________ testing the program goes through several development cycles in which the program is tested and requirements adjusted.

  iterative

  alpha

  conductive

  final

 5. A disadvantage of black box testing is that:

  if the code fails, the entire project will be contained in a metaphorical black box and put on hold

  none of these options

  if the code fails the tester will not know why it failed

  if the code fails, it will cause additional errors (hence the name black box)

 6. White box testing involves looking into the details of the algorithm. One method is:

  none of these options

  using a white piece of paper to write down the outputs based on random inputs

  using random input values and comparing the output against expected output

  using a trace table

 7. Iterative testing is when a programmer writes code, tests it and returns to it if there are errors, before moving on and doing the same for the next stage.

  FALSE

  TRUE

 8. Final Testing or User Acceptance testing is also called the ...

  none of these options

  final requirements check - done at the start of the final implementation stage

  project sign off (done when the project is complete)

  final acceptance strategy - where the end user pays the bill

 9. Final testing is broken down into two stages: Alpha and Beta

  FALSE

  TRUE

 10. Alpha testing is carried out by a group of volunteers unconnected to the development process and Beta testing is carried out by the developers.

  TRUE

  FALSE

 11. With the ___________ method, the project is split up into a number of stages. Read the excerpt to decide what method it is.
Each stage has a specific purpose. The end of each stage is called a milestone. The method is sequential so it looks like a cascade or waterfall.

  waterfall

  spiral

  None of the above

  systems life cycle

 12. In the 'pure' waterfall method there is no iteration - once a stage is completed you cannot go back.

  TRUE

  FALSE

 13. The reality is that most projects would employ the 'pure' waterfall method as they never have the need to go back to an earlier stage
Note: The waterfall method that allows for iteration and going back to previous stages is called the modified waterfall method

  FALSE

  TRUE

 14. In the waterfall method each step affects or influences the next (e.g. analysis stage influences the design stage)

  TRUE

  FALSE

 15. From the diagram, it is obvious that a late change to a project could have a….

  a negative effect as the project would be completed sooner than necessary

  big imapct on delivery time and costs

  wonderful effect in that it could speed up delivery time

  a positive effect because the proejct would then be cheap

 16. The waterfall method is suited for projects that are …

  high risk and unstable

  high risk and high cost

  well understood in terms of technology risk and have clear and stable requirements

  low risk and unstable in terms of requirements and objectives

 17. The disadvantages of the waterfall method include:

  requires extensive documentation and tight discipline that can stifle creativity

  Not suitable when the requirements are vague or for companies that prefer a more informal approach

  All of the above are valid disadvantages

  Clients do not always know what they want at the beginning of any project

 18. With the ______ model, if everything goes as expected, the project cascades through the systems life cycle, one after the other.

  Cartoon

  Spiral

  None of the above

  Waterfall

 19. The ___________ model is preferred over the waterfall model if the system is brand new and has a large number of unknowns or uncertainties.

  cartoon

  none of these options

  spiral

  concentric

 20. A test plan is a formal document that details the tests to be performed on software when complete.
A test plan details: the scope of testing, tests to be performed, 
reason for each test,data used in each test and the expected 
outcome of each test.

  False

  True
