Web Application Testing

With all the impending issues, web app testing holds more importance than ever. However, testing a web application is not just an ordinary task, and depends on several factors such as compatibility across various browsers, application performance, user experience, ensuring proper security, etc.

The enterprises must deploy skilled testers to assess all aspects of the website across platforms, browsers, and devices. The testers must always implement web application testing best practices in order to produce accurate and reliable test results without increasing testing times.

Web application testing Practices:

1. Emphasis on Cross-Browser Compatibility Testing

With more and more users accessing websites on their mobile phones and tablets, enterprises are exploring more ways to make their websites mobile-friendly. Responsive web design makes the web applications deliver a rich user experience on every device. To ensure that the web application is able to work well on all browsers and devices, developers build responsive websites by using open web technologies like HTML5, CSS3, and JavaScript. Hence, it becomes important to perform cross-browser compatibility testing to ensure that the website is accessible on every available version of individual web browsers.

2. Evaluate the Application’s Performance Under Various Conditions

In addition to assessing the proper working of the application on all devices and browsers, it is also equally important to ensure that it does not crash under heavy loads. Sometimes minor flaws in the coding or design can affect the website’s performance adversely. Therefore, it is important to perform load testing and evaluate how the application performs under varying loads. There are various automation load testing tools available to accelerate load testing.

3. Choose the Right Parameters for Usability Testing

Usability and the user-experience of the web applications are of the utmost importance to keep the visitors engaged and convert them into customers. Hence, it is important to evaluate the usability of the applications based on most appropriate parameters. Performing usability testing on the application before its release is a best practice. Usability testing involves several parameters such as UI design, speed, navigability, content readability, and accessibility.

4. Validate all Security Issues with Security Testing

Underestimating the significance of web application security is a ticking time bomb. Even a single vulnerability can lead to a massive data breach that can shake even the largest of companies down to its grounds, causing a negative impact, substantial financial consequences, and the loss of public trust. It is therefore imperative to ensure that the web application is thoroughly tested on the security front. A number of strategies that should be incorporated into the web application security testing are as follows:
• Defining coding standards and quality controls
• Creating strategies based on both internal and external challenges
• Using industry standards as a benchmark
• Implementing a cross-functional approach to policy building

5. Integrate Exploratory Testing in the Software Development Lifecycle

Exploratory testing reduces testing time and discovers more defects. As a regular practice in the software testing approach, testers write and execute test cases simultaneously. When failing to understand the shortcomings of exploratory testing, they are surrounded by more defects. By integrating exploratory testing with other black-hat and white-hat software testing techniques, the limitations of web app testing can be easily overcome. The integration can help in producing more reliable test results while reducing the testing time significantly.

What are the benefits of web application testing?

Compatibility across browsers:

 The practice of web application testing helps the applications to be compatible across all web browsers. Every user uses different browsers while surfing websites. The practice of web application testing effectively helps the apps to function the same for every user using different browsers. 

Improves website performance:

The methodology of web application testing successfully helps to overcome the slow app performance. Applications with slow performance are not the choice for any user and Google even. Web app testing helps to resolve the load time delays caused due to the graphics, code, etc. and maintains a quality application.

Secures App from vulnerabilities:

Security is one of the important concerns for every application. Day-by-day the rate of website hacks is excessively increasing, so there is an immediate need for every small and large enterprises to practice the web app testing to ensure that the applications are free from the different kinds of threats.

Ensures high quality of the application:

The end-to-end testing practice effectively helps in enhancing the performance and functionality of the app. And, this way of testing helps to find and resolve the bugs at earliest. Thus, a high-quality app will be achieved before the release.

Reduces the Time and Cost Consumption:

The end-to-end testing practice through automation tools reduces the occurrence of errors and the performance of repetitive test cases. This will help the enterprises to achieve quality results with reduced time and cost.

What are the challenges faced in web application testing?

Challenge in interacting with Firewalls:

There are several instances where a firewall or a port can block a web application due to the issues of security certificates. Therefore, to avoid these scenarios, it is mandatory to test the application across various firewalls.

Challenge for validating Web Services:

The modern web applications are prominently depending on the web service layers such as JSON/REST or XML/SOAP to exchange data between systems or applications. So, the need for testing these web services has become huge, but the web automating testing tools are not the ones to tackle the services. Hence, testing web services is one of the important challenges faced by the teams.

Challenge to maintain consistency across browsers:

 Interactive and Scalable web applications are always the preference of any user. If any inconsistency is experienced by the user while surfing on different browsers, then this can become a huge negative affecting the enterprise brand and growth. Hence, while performing usability testing, the developers need to monitor the interactivity and scalability of the app across different browsers by using different hardware.

Challenge to overcome performance issues:

An application with slow loading time is not a choice for any user and this drive affects the enterprise’s brand and app future. Hence, to overcome this challenge, developers should find the reasons influencing performance testing such as extending application features, interoperability, and integration issues, etc.

Challenge to secure app from data breaches:

Cyber threats are exceptionally increasing in number and affecting the user’s sensitive data which is available in the apps. In order to avoid data breaches and loss of information, it is important to regulate security testing practices. This will help to avoid the issues related to DDoS attacks and other cyber attacks and if there are any found, they can be resolved at the earliest. 

What are the tools for Web Application testing?

Selenium: 

Selenium is one of the leading open-source web automation tools. It helps to perform automation across different devices and browsers. Also, there are several options to choose the language for writing test scripts such as C#, Python, Java, PHP, JavaScript, etc.

TestComplete:

This is an easy-to-use functional test automation tool. It allows in creating and maintaining automated regression tests on various devices. This tool is efficient to run 1,500 tests in parallel across remote test environments.

Qase:

 This is a modern cloud-based test automation tool that is designed for helping QA and development teams. This tool doesn’t limit to run test cases or projects. 

Zephyr:

Zephyr is also a top tool providing end-to-end solutions for many small and big enterprises. A one-click can enable to integrate with Jenkins, JIRA, Bamboo, etc. Also, it provides a good number of deployment choices for the user.

Robot Framework:

This is an open-source tool with an test automation framework. It helps to drive a keyword-driven approach for acceptance test-driven development and acceptance testing.
