Design patterns can speed up the development process by providing tested, proven development paradigms. Effective software design requires considering issues that may not become visible until later in the implementation. Reusing design patterns helps to prevent subtle issues that can cause major problems, and it also improves code readability for coders and architects who are familiar with the patterns.

Design patterns were introduced to the software community in Design Patterns, by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides (colloquially known as the “gang of four”). The core concept behind design patterns, presented in the introduction, was simple. Over their years of developing software, Gamma et al found certain patterns of solid design emerging, just as architects designing houses and buildings can develop templates for where a bathroom should be located or how a kitchen should be configured. Having those templates, or design patterns, means they can design better [...] Continue Reading…

Testing tools often saves time and helps cutting testing time as web applications often suffers from bugs, inconsistent behaviors, usability issues, incorrect functionality, security issues and even the believed expectations of the customer. Its imperatively hard to determine bugs and fixes while development phase is in progress, keeping records drafting a bug sheet determining priority and severity will be a pain. Why not use automated test tools to test your web application. Following is a list of 10 web functional/regression testing tools for web applications in terms of Functional and Regression testing.
