Application Development

Risk

Just as with a traditional desktop application, web applications have varying levels of risk. A personal home page is much less risky than, for example, a stock trading web site. For some projects security, software bugs, etc. are major issues. If time to market, or technical complexity is a concern, documentation, test planning, change control, requirements analysis, architectural description and formal design and construction practices can mitigate risk.

[edit] Lifecycle Model

Time to market, company-growth and requirements churn, three things that are emphasized in web-based business, coincide with the principles of the Agile practices. Some agile lifecycle models are:

* Extreme Programming
* Scrum
* Timebox development
* Feature Driven Development

[edit] Testing

Web applications undergo the same unit, integration and system testing as traditional desktop applications. But because web application clients vary so greatly, teams might perform some additional testing, such as:

* Security
* Performance, Load, and Stress
* HTML/CSS validation
* Accessibility
* Usability
* Cross-browser

Many types of tests are automatable. At the component level, one of the xUnit packages can be a helpful tool. Or an organization can create its own unit testing framework. At the GUI level, Watir or iMacros are useful.
[edit] Tools

In the case of ASP.NET, a developer can use Microsoft Visual Studio to write code. But, as with most other programming languages, he/she can also use a text editor. Notepad++ is an example.

For ColdFusion and the related open source CFML engines, there are several tools available for writing code. These include Adobe Dreamweaver CS4, the CFEclipse plugin for Eclipse (software) and Adobe CF Builder. You can also use any text editor such as Notepad++ or TextEdit.

For PHP, the Zend Development Environment provides numerous debugging tools and provides a rich feature set to make a PHP developer's life easier.

Several code generation tools such as dbQwikSite or M-Power are available to automate the development of code. Using such tools, non-technical users can produce working code, and experienced coders can accelerate the development cycle.

Other tools include various browsers, FTP clients, etc. See Category:Web development software.
