Anything is possible while deploying a website: broken links, web security, difficult navigation, and other issues. Thus, a thorough testing strategy is critical for mitigating these risks and maintaining website quality.
This guide will address all questions about web testing, providing you with the information necessary to approach web app automation testing strategically and effectively.
What is Web Application Testing?
Web app testing is a software testing practice that ensures the application's functionality and quality as per the requirements. Before delivery, web testing must identify all underlying issues, such as security breaches, integration issues, functional inconsistencies, environmental challenges, or traffic load.
Why is Web Testing essential?
- Website testing is essential and required following the development of a feature since we cannot ensure to the customer the delivery of bug-free software without a proper web testing phase.
- Website testing enables the detection and reporting of product defects. If testers do not perform thorough testing, there is a high probability that end users may report issues. If customers are dissatisfied with the end product, they will hesitate to delegate any new feature to the team.
- If testers do not run rigorous web application tests, the risk of defects and the probability of losing customers is high. By compromising on the software's quality, there is a negative impact on the organization's reputation.
- Website testing is critical for delivering high-quality software. It is only by performing web page testing that developers can ensure that the product does not have critical flaws.
- Providing bug-free software in the market attracts new customers that eventually drive revenue generation.
Website Testing vs. Desktop Applications
- Website testing is URL-based testing and runs across many web browsers. On the other hand, testers carry out desktop application testing on a single computer or system.
- Desktop app testing requires an understanding of user interaction with the application. Furthermore, web app testing necessitates familiarity with the operating system and database.
- Testing desktop applications entails evaluating elements such as the graphical user interface (GUI), load, and backend. Memory leaks and unhandled exceptions must be evaluated during the desktop application testing process. Multiple users can access web apps concurrently through the internet. Web applications run on two or more systems; they are complex, necessitating extensive testing.
- In order to test a web application, the tester must be familiar with the application's functionality for interacting with the end-user. Website testing verifies the application's static page testing, browser compatibility, and overall feature functionality.
- Cross-browser testing is essential for web app automation testing, while it is not applicable for desktop application testing.
- Website application testing does not require Installation/uninstallation testing, while the same is required for desktop applications.
- Security/authentication testing is critical for website testing due to the application being accessed by several users. On the other hand, authentication testing might not be extensively performed on the desktop application as it is accessed mostly by a single user.
- Testers perform load testing to evaluate websites by simultaneously accessing the app with multiple users. On the contrary, desktop apps are used by a single user; hence, the app behavior is not analyzed when various users access them simultaneously.
Benefits of Web App Testing
- Web app testing ensures the delivery of high-quality websites.
- It enables a highly efficient product in the market with a high customer satisfaction index.
- Web testing assures that the software is fully functional.
- A sound web testing strategy helps in the early detection of bugs. It gradually increases tester velocity, as they can release new features more efficiently and quickly.
- Website testing helps in increasing customers' confidence in the application.
- Since QA testers run rigorous tests on the web application at the end of each iteration and sprint, there are fewer chances of risk and failure in the future.
- Testing a website via an automated website testing tool saves time and ensures a positive return on investment.
Web Application Testing Techniques
Here are some of the fundamental web application testing techniques:
1. Functionality Testing
The primary objective of functional testing is to ensure that all of the functionalities of a web application function smoothly without issues. Functional testing in a web application may include verifying whether all links are operating correctly, testing cookies, reviewing forms on all webpages, evaluating database security, and validating CSS or HTML.
Additionally, developers and testers should ensure that test cases cover necessary boundary conditions. Furthermore, invalid inputs should be backed by an appropriate error notification.
2. Web UI Testing
Critical components of a web app are the webserver interface, database server interface, and application server interface. Web UI testing validates that all components of the web application are well-connected. Testers should use this testing method to determine whether the interaction between these servers is carried out effectively.
3. Usability Testing
The application's user interface should adhere to industry standards regarding effectiveness and user-friendliness. It is also critical to adhere to global conventions and web standards while developing a web application. Usability testing is appropriate for apps that aim to automate manual processes.
However, testers must consider specific critical issues such as correct navigation, a site map, and avoiding over-crowded content while performing usability testing.
4. Performance Testing
Performance testing enables you to determine a web application's performance in various scenarios. It includes stress testing, load testing, and scalability testing. Typically, this testing method evaluates a website's functionality across different hardware platforms, operating systems, and more.
5. Compatibility Testing
Compatibility is a critical factor to be considered while testing a web application. Compatibility testing determines the compatibility of a web app with operating systems, browsers, mobile browsing, and other printing options.
6. Security Testing
Security testing is a critical web app automation testing method as it determines whether data modifications or leaks are tolerable. It primarily includes various activities such as verifying SSL, checking the CAPTCHA for automated script logins, and determining whether web files or directories can be accessed directly.
Challenges faced in web application testing
Interaction with Firewalls:
Challenges in connecting with firewalls arise because a port or a firewall can block a web app due to issues with security certificate compliance. Thus, it is critical to test the application across multiple firewalls to avoid such scenarios.
Validation of web services:
Modern web applications rely heavily on web service layers such as XML/SOAP or JSON/REST for exchanging data between applications or systems. Hence, the need for verifying these web services has increased significantly. However, web testing platforms are not equipped to handle them. As a result, testing web services is a significant problem for the QA teams.
Consistency across browsers:
Customers always prefer scalable and highly interactive web applications. If a customer encounters inconsistencies while browsing across browsers, it can adversely impact the enterprise's brand image and growth. Thus, developers and QA testers must track the app's scalability and interactivity across browsers and hardware configurations while conducting usability testing.
Addressing performance issues:
Users abandon any slow-loading web app, which eventually affects the company brand and revenue. Thus, to overcome this obstacle, developers should identify the factors affecting performance testing, such as scalability of the app's features, compatibility, and integration limitations.
Securing web app against data breaches:
There has been a constant rise in the number of cyber threats that can leak users' sensitive data. It is essential to monitor security testing processes to avoid loss of information and data breaches. It will help prevent DDoS attacks and other cyber threats. In case of any issue detection, testers can fix those at the earliest.
What is Automated Web App Testing?
Web application automated testing, or automated web app testing, evaluates a website's performance using varied types of automation website testing tools. It is a process in which various software tools are used to analyze a website's performance. The automated web app testing approach simplifies and standardizes web testing parameters in response to configuration changes during the development phase, conserving resources and providing consistent results to site administrators and owners.
Additionally, developers may perform relevant tests and compare results to predicted results by deploying efficient automated website testing tools. Consumers may occasionally encounter several bugs or error warnings while browsing certain websites, impairing the website's usability and readability. As a result, end-users abandon such web apps. These kinds of bugs and defects have a significant impact on businesses, as they can result in the loss of valuable customers. It indicates a lack of proper and effective web application automation testing on such websites. Thus, modern enterprises should leverage automated web app testing tools to ensure their websites perform seamlessly and deliver end-users with an uninterrupted experience. Different types of automated website testing include evaluating the functionality and usability of the web app, cross-browser compatibility, the performance of web apps under stress and load, and the accessibility and security of websites.

Website Testing Life Cycle
Testers use a web testing approach to evaluate apps launched using a web browser on the internet. In web page testing, QA testers carry out a set of processes before the actual testing.
Requirement gathering
In this phase, testers collect all requirements related to the feature and refine them and identify the gaps.
*Test Planning *
In this phase, testers update the test plan document with a definition of the test scope and objectives, strategy, the entry and exit criteria for web testing, and an evaluation of the test estimate.
Test case preparation
QA testers generate test scenarios and scripts using the most appropriate automation technique considering the test strategy as a guide.
Test Execution
At this stage, testers run the defined test cases and document any deviations from the intended result.
Bugs Reporting
If a test case fails during execution and a bug is detected, testers raise and report it using a defect tracking tool like Jira and HP ALM QC.
*Defect Retesting *
Once the developer has fixed the defect, testers retest it and re-execute the failed test case.
Test Closure
The test cycle is closed once all defects are fixed and the web application is functioning as expected. If not, QA testers repeat the process.
