Usability and software test for web application

Navigation

Navigation describes the way users navigate within a page, between different user interface controls (buttons, boxes, lists, windows etc.), or between pages via e.g. links. To determine whether or not your page is easy to navigate through consider the following. Is the application’s navigation intuitive? Are the main features of the site accessible from the main page?

Do the site need a site map, search engine, or other navigational help. Be careful though that you don’t over do your site. They rarely take the time to learn about the sites structure, and it is therefore important to keep the navigational help as concise as possible.

Another important aspect of navigation is if the site is consistent in its conventions regarding page layout, navigation bars, menus, links etc. Make sure that users intuitively know that they are still within the site by keeping the page design uniform throughout the site.

As soon as the hierarchy of the site is determined, testing of how users navigate can commence.

Summary:

  1. Intuitive navigation
  2. Main features accessible from main page
  3. Site map or other navigational help
  4. Consistent conventions (navigation bars, menus, links etc.)
  1. Graphics

The graphics of a web site include images, animations, borders, colours, movie clips, fonts, backgrounds, buttons etc. Issues to check are:

  1. Make sure that the graphics serve a definite purpose and that images or animations don’t just clutter up the visual design and waste bandwidth
  2. Verify that fonts are consistent in style
  3. Suitable background colours combined with font- and foreground colour. Remember that a computer display exceptionally well presents contrasts apposed to printed paper
  4. Three-dimensional effects on buttons often gives useful cues
  5. When displaying large amount of images, consider using thumbnails. Check that the original picture appears when a thumbnail is clicked
  6. Size – quality of pictures, usage of compressed formats (JPG or GIF)
  7. Mouse-over effects
  1. Content

Content testing is done to verify the correctness, accuracy and relevancy of information presented on the site, or in a database, in forms of text, images or animations.

Correctness is whether the information is truthful or contains misinformation. For example wrong prices in a price list may cause financial problems or even induce legal issues.

The accuracy of the information is whether it is without grammatical or spelling errors. These kinds of verifications are often done in e.g. Word or other word processors.

Content testing should be done as early as possible, i.e. when the information is posted.
