  2. 2. How to use this presentation This presentation will quiz you on SOME of the key topics that in this unit. Questions will be shown. Think of the answer or write it down. Advance the slide to reveal the answers. Note that the slides are numbered. Note down the number of any slide that you got wrong and repeat these questions until you can answer all questions confidently. Remember that while this quiz is helpful, it is no substitute for working through SQA past papers which is the BEST way to prepare for exams and to practice more of the types of questions that will appear on the exam.. 2

  79. 79. Once a multimedia application hasbeen completed, it must be tested before it is released. Name and explain the two types of testing. Screen testing: Compares screen layout to design to check that all required elements are there (text, images, links). It checks that images, movies, etc work properly. It does not check that links work! Navigation testing: Tests that there are no “dead” links and that all links work correctly. 79
