Best Practices in Web Application Testing

weWith more and more users accessing websites on their smartphones, tablets and phablets, it has become essential for businesses to optimize their web applications for mobile devices. At the same time, each business needs to test the web application thoroughly to ensure that it delivers richer user experience across many browsers and under various conditions. While testing modern web applications, QA professionals have to address challenges related to integration, interoperability, performance, usability and security. So the QA professionals must follow simple best practices to test the web applications more effectively.

7 Best Practices for Web Application Testing

1) Focus on Cross-Browser Compatibility Testing

Nowadays most businesses opt for responsive web design to make their web applications deliver richer user experience on each device. The new approach requires programmers to make websites responsive by using open web technologies like HTML5, CSS3, and JavaScript. At present, older versions of certain web browsers do not support HTML5 fully. So the testers need to check how the app performs on both older and current versions of major web browsers. They can even use specialized automation tools to test the application across many browsers quickly and efficiently.

2) Test Each Important Element of a Web Application

While testing a web application, QA professionals often focus on its features, functionality and performance. But a business must ask the testers to assess each important element of the website in addition to its functionality and performance. For instance, the QA professionals must assess key elements of the web application including cookies, CSS, JavaScript, HTML validity, dead-links, browser refresh, windows resizing, and security. The comprehensive testing will make the website deliver richer user experience over a longer period of time.

3) Assess the Application’s Performance under Various Conditions

In addition to assessing the stability of the website’s functionality, the testers also need to ensure that it does not crash under heavy load. Sometimes minor flaws in its design or code also affect the website’s performance negatively. So the testers must assess the performance of the application under a variety of loads to check how it caters to a large number of visitors. They can even use open source load testing tools to assess the performance of the application under varying load on the server effectively. Likewise, they must perform load testing repeatedly to ensure that the performance of the website is not impacted by the changes made to the code.

4) Scale the Load Tests Incrementally

In addition to assessing the performance of the website under varying loads, it is also important for the QA professionals to scale the load tests incrementally. In the initial stages, they should replicate a comparatively smaller number of distribute user, and increase the number of users gradually. When the number of users increases gradually, it becomes easier for software testers to identify the exact point where the application crashes. However, the QA professional must perform load tests in cycles and analyze the load testing result of each cycle to assess the performance of the website accurately.

5) Don’t Forget to Check HTTP Traffic

While testing a web application, businesses often forget the significance of analyzing the web traffic. When the testers check the HTTP traffic thoroughly from the browsers to the server, it becomes easier for them to assess each request and response precisely. At the same time, the HTTP traffic analysis helps them to test Google Analytics tags and similar third-party tracking tags used by the web page. The testers can further use specialized tools to ensure that each tracking tag includes correct values, and the third-party systems respond to the user requests quickly and properly.

6) Test the Web Services Independently

Nowadays most web applications use a variety of web services. But the business needs to ensure that the web services used by the application are tested independently, and as isolated components. The testers must test the web services before they are integrated with the application. The option will enable them to test the web services more quickly, while exercising better control over their functionality. Also, the testers can send a variety of request to the web browser directly and assess its performance without using a web browser.

7) Pick the Right Parameters for Usability Testing

The business must focus on both usability and user-experience of the web applications to keep the visitors engaged and convert them into customers. However, it is also important for the testers to assess the usability of the applications based on the most appropriate parameters. The business must clearly define the key criterions for performing usability testing. At the same time, the business also needs to pick a number of key criterions like user interface design, speed, performance, readability of content, accessibility and navigability. Likewise, it must ask the testers to determine the amount of time required by a user to perform specific tasks.

A business can always automate its testing efforts to quickly check the look, feel, usability and performance of the web application across many web browsers. However, it also needs to focus on development, maintenance and reusability of automated tests to test the frequently changing front-end of the web application more effectively.

 

Easiest Way to Learn Computer Programming

prIf you are really interested to learn Java then you are at the right place because here in this article you will find an overview of Java basics over here. So here it is a provision for you for as a self guided version. There would be plenty of code examples as you move ahead with this article.

This first article presents the Java system and describes the distinction between its three editions: Java SE, Java EE, and Java ME. You’ll also learn about the part of the Java Virtual Machine (JVM) in implementing Java applications.

A general purpose and an object oriented language that looks a lot like C and C++ but is easier to use and allows you to create more programs.

A network-savvy language: TCP/IP network protocols like HTTP and FTP and it can be easily coped up with extensive network library of Java. And they can access the URLs in an easy way as if its is a normal file.

Java is a robust language: Java programs must work because they are used in both client and mission-critical programs, different from Blu-ray players to vehicle-navigation or air-control techniques. Language functions that help make Java effective statements, duplicate type confirming at compile time and play-back, real arrays with computerized extensive variety confirming, and the omission of pointers.

Java is a convenient language: Structure neutrality leads to mobility. However, there is more to Java’s mobility than platform-independent bytecode guidelines. Consider that integer type sizes must not differ. For example, the 32-bit integer type must always be finalized and take up 32 bits, regardless of where the 32-bit integer is prepared (e.g., a system with 16-bit signs up, a system with 32-bit signs up, or a system with 64-bit registers). Java’s collections also play a role to portability.

Java is a multithreaded language: To improve the efficiency of programs that must achieve several projects at once, it facilitates the idea of threaded efficiency. For example, a program that controls a Graphical User Interface (GUI) while patiently awaiting feedback from a system relationship uses another line to perform the delay instead of using the standard GUI line for both projects. This keeps the GUI responsive.

Java is a secure terminology: Java applications are used in networked/distributed surroundings. Because Java applications can move to and perform on a network’s various systems, it’s important to protect these systems from harmful code that might spread malware, grab bank card information, or perform other harmful functions. Java terminology functions that support sturdiness (like the omission of pointers) work with protection measures such as the Java sandbox protection model and public-key security.

Java is a high-performance language: Presentation results in a level of efficiency that is usually more than adequate. For very high-performance application circumstances Java uses just-in-time collection, which examines considered bytecode training series and gathers frequently considered training series to platform-specific guidelines. Following efforts to understand these bytecode training series result in the performance of equivalent platform- specific guidelines, leading to an efficiency boost.

Java is an object-oriented Programming (OOP’s): Java’s object-oriented concentrate allows developers work on adjusting it to resolve an issue, rather than pushing us to control the issue to meet terminology constraints. This is different from an organized language like C. For example, whereas it allows you concentrate on bank consideration objects, C requires you to think independently about bank consideration state (such a balance) and actions (such as deposit and withdrawal).

Sun fixed the submission issue by considering Java into three main versions. These gradually became known as Java SE, Java EE, and Java ME:

Java System, Standard Edition (Java SE) is the Java platform for creating client-side applications, which run on desktop computers, and applets, which run in Internet Explorer.

Java System, Enterprise Edition (Java EE) is the Java platform designed on top of Java SE, which is used specifically to build up enterprise-oriented server applications. Server-side applications include servlets, which are Java applications that are similar to applets but run on a server rather than a customer. Servlets adjust to the Java EE Servlet API.
