Web Applications have reached to a level that all kinds of Organizations are implementing them for a variety of purposes and those applications are accessible to several categories of Users. The vulnerability of the application increases with the huge number of users and with the value contained within the Application. This blog provides a highlevel list of testing activities that need to be carried on Web Applications before moving them to production environment.

By default testing team does a functional testing for all web application to make sure that all intended actions are properly carried out by the application. This includes checking various modules,links, forms and validations. Negative test cases verification also takes place to prevent the application from acting against the purpose.

Usability Testing:
Usability testing has gained traction recently to make sure that the user receives the best possible user experience while using the application. This includes checking menus,buttons,check boxes, user controls and navigation between modules. Legibility, readability, understandability, colors, images, fonts are other important aspects that get tested in this process.

Compatibility Testing:
The Web Application should be compatible with several environments in terms of display, usage and actions. This includes Browser compatibility, OS Compatibility and Mobile Compatibility. The application has to be tested across different browsers to ensure consistency in performance in them. Also the application should be working different operating systems with the same usability and interface. Then comes the most important aspect of compatibility in mobile devices such as Smart Phones, Tablets and Laptops.

Integration Testing:
The integration of the web application between databases, user interfaces, server, third party integrations are very important and testing of the same becomes crucial for a web application to function properly. Connectivity between various above mentioned items and exchange of data between them has to be tested exhaustively.

Performance Testing:
The performance of a Web Application has to be consistent even during heavy load with huge number of users doing resource intensive actions within the application. The database should be tested for handling number of transactions and the application load time and response for user actions need to be thoroughly tested.

Security Testing:
Security forms the most important testing category as Web applications are vulnerable because of their exposure to Internet. The URL, database, files and any sensitive data should be protected from attacks and that need to be tested properly. User session testing, unauthorized usage prevention,encryption of data are few items that need a mention during the Security testing of the application.

Only when all of the above testing functions are carried out properly can we ensure the production migration of the web application for public use.
