The modern day Internet offers new challenges to web application developers.  Online networking, e-learning and e-commerce have gained immense popularity thanks to Rich Internet Applications. RIAs have completely changed the way people use the net today. Businesses have also embraced online marketing to tap the global customer base through interactive and attractive online presentation. The changing tastes of the end users have pushed the web application developers to adopt the latest technology and tools to rapidly create more responsive and intelligent RIAs. The Flex developers use latest offering from the Adobe Flex- Flex4 in the Flex development process to create more interactive RIAs.

Flex 4 empowers developer to add more life into the RIAs by supporting 3D features. The new charting library allows the developer to create intelligent applications that interact with the clients and convey the useful business information at a click of button. The online business enjoys a greater online expression by displaying rich graphics that quickly get crucial business message or information across the board. Flex 4 uses the Spark architecture that makes it possible for the Flex developer to work side by side a designer in the Flex development process. This saves RIA development time. Moreover automated testing takes off the human interference in the code testing and ensures quicker completion of the de-bugging process so that RIA can be deployed easily, free of any flaws.

The Flex developer uses another great testing tool, know as Flex Monkey. This tool can be used by both Flex developer and QA tester. It is vital for Flex development because it prevents regression, i.e., breaking of previously working code, to set in. Since coding a complex RIA consumes time, any overlooked coding error causes the predecessor code to malfunction. This creates flaws in the RIA development and seriously affects the functionality of the application. RIAs are user-centric hence Flex Monkey checks the coding from top to bottom for any regression and ensures that all the re-factored codes are working normally. The Flex Monkey equips the Flex developers with a combination of recorder, code generator and API so that they can create automated user interface tests to check how the application will behave or perform after its deployment.

Thus Flex 4 and Flex Monkey help the developer  create and deploy more intelligent RIAs in a seamless manner so that multitude of users can access applications  and have a delightful user experience.
