Software Testing Methodology Question:
Explain Black Box testing for web-based application Part 1:
Answer:
1. Browser functionality:
* Is the browser compatible with the application design?
* There are many different types of browsers available.
# GUI design components
* Are the scroll bars, buttons, and frames compatible with the browser and functional?
* To check the functionality of the scroll bars on the interface of the Web page to make sure the the user can scroll through items and make the correct selection from a list of items.
* The button on the interface need to be functional and the correct hyperlink should go to the correct page.
* If frames are used on the interface, they should be checked for the correct size and whether all of the components fit within the viewing screen of the monitor.
2. User Interface
One of the reasons the web browser is being used as the front end to applications is the ease of use. Users who have been on the web before will probably know how to navigate a well-built web site. While you are concentrating on this portion of testing it is important to verify that the application is easy to use. Many will believe that this is the least important area to test, but if you want to be successful, the site better be easy to use.
3.Instructions
You want to make sure there are instructions. Even if you think the web site is simple, there will always be someone who needs some clarification. Additionally, you need to test the documentation to verify that the instructions are correct. If you follow each instruction does the expected result occur?
4. Site map or navigational bar
Does the site have a map? Sometimes power users know exactly where they want to go and don't want to wade through lengthy introductions. Or new users get lost easily. Either way a site map and/or an ever-present navigational bar can help guide the user. You need to verify that the site map is correct. Does each link on the map actually exist? Are there links on the site that are not represented on the map? Is the navigational bar present on every screen? Is it consistent? Does each link work on each page? Is it organized in an intuitive manner?
5. Content
To a developer, functionality comes before wording. Anyone can slap together some fancy mission statement later, but while they are developing, they just need some filler to verify alignment and layout. Unfortunately, text produced like this may sneak through the cracks. It is important to check with the public relations department on the exact wording of the content.
You also want to make sure the site looks professional. Overuse of bold text, big fonts and blinking (ugh) can turn away a customer quickly. It might be a good idea to consult a graphic designer to look over the site during User Acceptance Testing. You wouldn't slap together a brochure with bold text everywhere, so you want to handle the web site with the same level of professionalism.
Finally, you want to make sure that any time a web reference is given that it is hyperlinked. Plenty of sites ask you to email them at a specific address or to download a browser from an address. But if the user can't click on it, they are going to be annoyed.
6. Colors/backgrounds
Ever since the web became popular, everyone thinks they are graphic designers. Unfortunately, some developers are more interested in their new backgrounds, than ease of use. Sites will have yellow text on a purple picture of a fractal pattern. (If you've never seen this, try most sites at GeoCities or AOL.) This may seem "pretty neat", but it's not easy to use.
Usually, the best idea is to use little or no background. If you have a background, it might be a single color on the left side of the page, containing the navigational bar. But, patterns and pictures distract the user.
