Javascript Testing Tools
JavaScript has long been an important term in the overarching fields of software development and software testing, also known as software quality assurance testing. Basically, JavaScript is a scripting language designed to cater to the needs of client-side web development. Although it is more known as JavaScript, in computer terminology, it is also called in its standardized name, ECMAScript. At present, JavaScript is Mozilla Foundations, originally under Netscape Communications Corporation, implementation of the ECMAScript Standard. Under Mozilla, JavaScript has developed into a prototype-based, weakly typed, dynamic language. Influenced by many languages, it was likewise designed to be user-friendly for non-programmers. Its best use is seen in websites, as client-side JavaScript, though it is also used for access into other applications. As a registered trademark of Sun Microsystems, Inc., JavaScript was used for Netscape's and Mozilla's technology, invention, and implementation.
JavaScript occupies an important place in website design and management. It is the language used for functions included or embedded in HTML pages. It is also the same language to interconnect with the Document Object Model or DOM of a webpage. Thus, in a website written in JavaScript, one use would be the popping up of a new window with control on its size or position. It also serves the purpose of approving web forms to ensure that they are accepted before reaching the survey. JavaScript also includes features where images change with the movement of the mouse. This is a common feature of retail or promotion websites. Its aim is to draw a visitor's attention to other parts of the site.
Because of its wide use, it is important that tools of assessment be used to make sure it performs well. For a software engineer, learning the ins and outs of the JavaScript language is a necessary skill. There are many JavaScript Testing Tools available, depending on the type of software you are using. One of these is JKool, which is a lightweight measurement on performance. It is an effective monitoring tool for Web as well as Web service-based applications. It proves to be effective in giving timing information as well as Java method calls, JMS, and JDBC. Another measurement tool is the StrutsTestCase for JUnit. An open source extension for standard JUnit TestCase class, it also has in-built validation systems, making easy and quick for writing unit test cases. Another JavaScript testing tool is the JavaNCSS, a source management suite for Java. It comes with various code metrics.
There are also testing tools for JavaScript that run directly in browsers. Some could even work in different types of Internet environment such as Firefox, Linux, Mozilla, and Macintosh. These tools specialize in browsing compatibility tests and system functional tests, both testing tools to assure that applications work correctly according to its product specifications. Like all other software testing tools, JavaScript testing tools aim to detect errors in the system for excellent system performance. The domain of the Internet is a good place to transact and interact with people and build stronger relationships with clients. However, with errant websites, an organization can lose that all. JavaScript testing tools becomes necessary.
