Factors affecting Testing of Web Applications

Edit Article |

Posted: Sep 13, 2010 |Comments: 0


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.
