The Secret | Of Web Testing

Nowadays, the majority of people cannot spend even a day without the Internet. They use various applications for different purposes. And all web software products should be reliable and safe. Only apps with proper functioning will be popular among users.

That is why web testing services are very wide-spread. This checking type has a set of specifics which every software tester should know. One of such peculiarities is that web services can be tested in isolation. It simplifies the QA specialist's work.

What Are the Advantages of Testing Isolated Web Services?

• A browser is not engaged in the testing process. A test engineer is able to interact with a web server directly.
• The speed of server response is faster, as a set of various pictures, JavaScript, and CSS elements should not be loaded. As a result, the testing procedure takes less time.
• The isolation of web server helps to fix the found bugs quicker and easier. And of course, the issue debugging will require less time if its location can be easily defined.
• The total control over the tester's interaction with the web server is available. The specialist makes the particular requests that will be submitted to the web server. As a consequence, the execution of negative testing is as easy as ABC.

During this software testing type, the specialists may use SoapUI, an open source cross-platform tool. Besides that, some plugins may be also used to check web servers. It may be, for example, REST Clint for Firefox.

An inevitable part of web product testing is the check of the HTTP traffic. With its help, the specialists can analyze every request and response in details. But it is handier to review the traffic if it is visualized. For this purpose, the testers use several tools.

What Are the Tools For HTTP Traffic Analysis?

• Fiddler (to monitor traffic)
• Wireshark (to review everything in the network)
• Live HTTP Headers (to see only headers)
• FireBug (can be used to monitor AJAX transactions)

But these tools have their own peculiarities. For instance, Live HTTP Headers is a plugin for Firefox.

Web application testing has a rather complicated procedure, as a lot of various aspects of the product should be checked. Cross-browser testing plays an important part here, as different users may use various browsers. The specialists pay much attention to performance testing, as the number of users can be really large and the product should function properly in such a situation. In most cases, the test automation helps to conduct the checking process faster.

But nevertheless, there is a huge number of important elements that should be checked during web application testing. Among them, there are cookies, security, refreshing of a browser, dead-links, HTML validity, etc.

To perform mobile testing, desktop testing or web site testing efficiently these methods should be adjusted for each company and each project.
