Web design, Development and Testing

Many organizations are interested in Web applications for their business, but are not aware of the various steps that are required to have to create a compelling web application. In this article I will try to collect different pieces of the puzzle. The development of applications includes several different efforts to come together to build a compelling final product need. A final product is the compelling combination of design, architecture, development, implementation of development, regression and automated functional testing and performance and load testing.

Design: People often confuse the web design and development. In addition, also in design, user interface design is often confused with graphic design. Web design includes user interface design Site flow and presentation of certain web pages within the site. The Web User Interface Designer is focused on the usability of the application. The user interface designers typically develop “wire” by using tools like Adobe Photoshop, to bring the design to express. They are often initially developed as prototypes and usability tests, conducted with groups of users to ensure that the web application intuitive and easy to use. The graphic design on the other hand refers to the aesthetics of the page. The designer is responsible for the aesthetic design of the pages and create various graphical objects in pages such as images and Flash objects. The developer of graphics typically use a combination of tools such as Adobe Photoshop, Adobe Illustrator and Adobe Captivate to create the actual graphics objects. A designer will ensure closely with other groups in order to not compromise the design process, the demand by ensuring that the small graphic objects are thus ensured that the various web performance metrics are not affected.

Development: This is the transformation of the design in a real application. The development phase usually consists of an architecture in which the underlying modules, which excluded the application are included. If symptoms persist data storage is required, a database schema should be to meet the needs of data storage. The choice of operating system (Windows, Linux or Solaris), where the Web application is running, the Web server (eg Microsoft IIS Apache, or Tomcat), the Web application, and opens to the back-end data base ( such as Microsoft SQL Server, Oracle, MySQL or Postgres) that stores the data should be made. Various development framework for creating Web applications. The most common are ASP and ASP.NET Microsoft, Java Servlets and JSP Sun, PHP and Perl that are open source. The choice of application framework is usually dictated by the forces of the members of the development team. The architecture phase is followed by the phase of implementation. This is usually the longest part of the project and during this phase, the code is written, developed using the specifications of design and graphic objects by the design team. The programming is usually done with a combination of frameworks mentioned above with HTML, JavaScript and CSS.

Quality Assurance and Testing: A surprising number think of people that quality assurance and testing is desirable but not really necessary. Unfortunately, this theory has its roots in complete ignorance of the process required to produce a finished good. Regardless of how pretty tablecloth or we ask if it does not work as expected, users will reject it. Quality assurance and testing involve two types of tasks. Functional testing and regression testing is used to ensure that the developed application does what it should do. This is achieved through test automation tool for functional tests. Load and performance testing is used to ensure that the application works as expected when the load exposed to a typical production environment. Load test is virtually impossible to achieve without the help of an automated load testing, as is the simulation of a large number of concurrent virtual users. This effect can not be carried out manually and really needs the help of an application that is specified for the intended application of the fee, and then measure the performance when this stress. Quality assurance teams will follow the bugs or errors in the application with the bug-tracking tools. These tools allow interference from all members of the team followed.

The above three categories tend to be specialized for their skills. For example, people often make the mistake of the developers use as a tester for quality assurance. This is not a sensible strategy, since most developers are good at writing software unfortunate enough to find errors or mistakes in their software.

Writing good and compelling Web applications, it must include all phases of the process, design, development and quality assurance. Skipping phases or cut corners will mean a low quality software, which are generally more expensive long term.
