Various Areas Of AJAX Testing
One of the key aspects of software development is software testing. You can not deploy any software unless it has undergone serious testing effort.
Asynchronous Java script And XML (AJAX) is one of the primary building blocks of Web 2.0 applications. It is based on the XMLHttpRequest, an object developed by Microsoft. It runs both like any standard application and website. Like any code work, AJAX testing is very important because there are a number of things which you have to be sure about before the system goes live. Here is a look at some of the common areas where AJAX testing is done.
First thing to be tested is the browser compatibility. It is of utmost importance that your AJAX application must be able to run with complete features in every browser. Naturally the number of browsers makes it extremely difficult to make sure that it would run in every single browser in the world. It is a must that your AJAX code must be able to run properly in the big four browsers in the market namely Internet Explorer, Mozilla Firefox, Safari and Mac OS X.
The solution which is used to write AJAX code generally provides you inbuilt compatibility testing features. It is also a good idea to manually test all kinds of functionality of the AJAX code in all the browses as you would be able to take the latest browser version with all updates in account.
Second thing is standards compliance. The regulatory authorities of the world wide web have standardized the format in which code is written as well as the tags and code is written. These standards are officially optional but the main advantage if you adhere to these standards is that your AJAX code wold execute properly in every client browser that is standards compliant. Moreover being standards compliant means that you do not get into vendor or host lock ins. Hosting server can be easily changed.
The third thing is security testing. Security testing is done to ensure that any vulnerabilities of the code do not pass on the control of server to any malicious user. In such a case grave concerns related to client data would arise. Security testing is also to be done where the AJAX code makes use of the SSL or any other form of encrypted communications system. This is done to make sure that any Man In The Middle attacks for data or identity theft do not occur.
Finally you have to do is load testing which is done to make sure that the code and the hardware on which the website is to run is to run can take a huge amount of users. Since the performance is at stake, this is very important .It is also a way to see how long the AJAX application can stand up against a Denial of Service or Distributed Denial of Service attack.
