Sept. 23, 2010 - PRLog -- Web Applications can have a lot of variables affecting them such as:
 - Numerous Application Usage (Entry – Exit) Paths are possible
   Due to the design and nature of the web applications it is possible that  different users follow different application usage paths.
 For example in an online banking application a user may directly go to “Bill  Pay” page and other users may check account balances, view previous  transactions and then “Pay the Bills”.
 Generally a large number of usage paths are possible and all are supposed to  work well.
 All these Permutations and Combinations need to be tested thoroughly
 - People with varying backgrounds and technical skills may use the  application
 Not all applications are self explanatory to all people. People have  varying backgrounds and may find the application hard to use. For instance a  Business Intelligence application with “Drill-Down-Reports” may work out for  certain users but not for others.
 Although this affects the design of the applications, but these factors  should be tested in usability testing of the applications
 - Intranet versus Internet based Applications
 Intranet based applications generally cater to a controlled audience. The  developers and architects can make accurate assumptions about the people  accessing the apps and the hardware/software/technical specifications of the  client machines.
 While it may be difficult to make similar assumptions for Internet Based  Applications
 Also the intranet users can generally access the app from ‘trusted’ sources  whereas for internet applications the users may need to be authenticated and  the security measures may have to be much more stringent.
 Test Cases need to be designed to test the various scenarios and risks involved.
 - The end users may use different types of browsers to access the  app
 Typically for Internet based applications users may have different Browsers  when accessing the apps. This aspect also needs to be tested. If we test the  app only on IE then we cannot ensure if works well on Netscape or Fire-Fox.  Because these browsers may not only render pages differently but also have  varying levels of support for client side scripting languages such as  java-script.
 - Even on similar browsers application may be rendered differently  based on the Screen resolution/Hardware/Software Configuration
 - Network speeds:
 Slow Network speeds may cause the various components of a Webpage to be  downloaded with a time lag. This may cause errors to be thrown up.
 The testing process needs to consider this as important factor specially for  Internet based Applications
 - ADA ( Americans with Disabilities  Act)
 It may be required that the applications be compliant with ADA. Due certain disabilities, some of the  users may have difficulty in accessing the Web Applications unless the  applications are ADA  compliant. The Application may need to be tested for compliance and usability
 - Other Regulatory Compliance/Standards:
 Depending on the nature of the application and sensitivity of the data captured  the applications may have to be tested for relevant Compliance Standards. This  is more crucial for Web Based Applications because of their possible exposure  to a wide audience.
 - Firewalls:
 As mentioned earlier Applications may behave differently across firewalls.  Applications may have certain web services or may operate on different ports  that may have been blocked. So the apps need to be tested for these aspects as  well.
 - Security Aspects:
If the Application captures certain personal or sensitive information, it  may be crucial to test the security strength of the application. Sufficient  care need to be taken that the security of the data is not compromised.
