At different levels of industry as well as individual practices, different software apps are deployed and incorporated in the business model in order to perform technical tasks and operations in a more streamlined manner. Furthermore, several development technologies are tried and tested in the making of such software, in order to render them with maximum effectiveness and innovativeness. The scope of the application is expanded by putting different technologies at work.

Designing sites or web apps for the mobile web is not a task that most designers like, as it is rather difficult. The user interfaces are optimized for use with fingers and not with a traditional mouse cursor that most people are used to. Moreover, there are bandwidth limitations to contend with. Hence, for people who have been designing for desktops all this while, there is going to be a drastic change in the way they need to think. JavaScript frameworks come to your rescue and help make the task easier.

Error handling is a very important topic, not only in JavaScript but also in development in general. Let’s face it. Even if you write the most perfect code, once you put your code outside of the local environment to users to use, chances are, your code will fail eventually. Your code can fail due to numerous reasons, for example, user can enter some erroneous data or they can have networking issues. When this happens, it is important to show the user informative and appropriate error message. Otherwise, you may cause frustration on the user end, which is something that either the programmer nor the user want. So let’s take a look at the example of how we can handle errors in JavaScript.

Testing is a crucial step in the app development cycle. The app needs to be tested before the final deployment to ensure that it has the load management capabilities and can perform the task under extreme working conditions and workload.

There is the number of open source testing tools available in java language, which are used by test engineers and Quality Assurance teams to validate and verify the developed applications before the final deployment. Let’s look at famous four java testing tools, that are widely used by test engineers and quality assurance teams.
