Errors are good!
  • If you create a system and tell me that you
    tested it and found no problems I simply wont
    believe you
  • In documenting your testing I expect you to state
    clearly what errors you found and what you did
    about them in your test logs

4
When to Test
  • Formative testing
  • Testing during development
  • Summative testing
  • Testing after development
  • Imagine a chef making soup
  • The formative stage is the chef tasting the soup
    as they make it
  • The summative phase is when the customer tastes
    it

5
Why do we test?
  • To find faults or errors with the code
  • Establish accessibility
  • Understand the level of usability
  • We need to have our designs viewed through fresh
    eyes to see the things that are hard to see
    ourselves

6
What do we test?
  • For the sake of this lecture I shall split
    testing into three types
  • System testing
  • Accessibility testing
  • Usability testing

7
System Testing
  • You will need to consider issues such as the
    following
  • Is your code correct? Validation broken links
  • Does your design work on different browsers?
  • Does your design work at different screen
    resolutions?
  • How does your design behave on different computer
    platforms?

8
Is your code correct?
  • Tools in DreamWeaver
  • Validate your XHTML by pressing Shift F6
  • Link checker shift F8 (ctrl F8 for the site)
  • Test your links on a friends machine!
  • Clean up XHTML
  • Site Reports
  • Spell Check (Set to British not American)

9
Platform Tests
  • Different browsers. (Internet Explorer, Firefox,
    Opera)
  • Different Screen Resolutions (Design for liquid
    layout, use percentage values in positioning)
  • Different operating systems? (PC, MAC, Unix)

10
Browsers
  • Browser usage for the faculty dated 19th Oct 2008

11
Browser Wars
  • Early 1990s and following
  • Netscape
  • Internet Explorer (Given away for free)
  • The marquee tag Microsoft only tag
  • Need for CSS XHTML not good for layout
  • World Wide Web Consortium http//www.w3.org

12
Resolution Testing
  • At least change the browser window size
  • Change the resolution on your machine

13
Accessibility
  • Some questions
  • Do all of your images have an alt tag?
  • Does your site work without the colours? (Rename
    your style sheet to test this.)
  • Can you still navigate your site if flash doesnt
    work?

14
Usability Testing
  • Usability may be defined by the following
    questions
  • How easy is the site to learn?
  • How quickly are tasks performed?
  • How easy is it to remember how to use the site?
  • How many errors does a user make?
  • Is the user satisfied with the experience?

15
Usability Testing
  • Who to use?
  • How many test subjects?

16
Approaches to Testing
  • Focus Groups
  • Testing the Paper Based Design
  • Card Sorting
  • Design an Experiment
  • Planning Test Scenarios
  • Give the subjects a specific task
  • Avoid Polluting the Test
