Web Application Testing: The Basics of Automated Web App Testing
Testing the functionality of web applications is becoming increasingly important as more traditional front- and back-office programmers migrate to web-based interfaces. As a result, knowing what to automate and how to automate is an important part of web app testing success.
As more apps and services are transferred to a single platform – web-based – IT landscapes across enterprises are becoming increasingly simpler. However, there are a few drawbacks:
Web apps and websites must work across many browsers, browser versions, operating systems, and devices, including mobile, to provide a fantastic end-user experience.
The number of usage scenarios to be examined skyrockets when all the conceivable combinations are considered.
Sauce Labs, a provider of hosted environments for automated web testing, has discovered over 2,000 devices and over 800 browser-OS combinations, and those are just the most popular.
What does it mean to test a web app?
Web testing, often known as web application testing, is a software activity that maintains quality by ensuring that a web application’s functionality is performing as planned or according to the requirements. Web testing enables you to uncover flaws at any moment, whether it’s before a release or on a daily basis.
Testing is an essential component of software development. Bugs can arise anywhere in the system whenever there is a change in the code, no matter how minor. Because the cost of addressing these vulnerabilities increases over time, having efficient web testing in place will help you save time and money when developing your app.
What is the best way to test web applications?
Developing a high-quality online application necessitates extensive testing, which may be laborious and time-consuming if done manually. As a result, many QA teams rely on automation to develop quick, efficient, and trustworthy test cases for their online applications.
These normal and repetitive testing duties are delegated to machines by test automation. Actual and anticipated outcomes are compared in the testing. This method can aid in the detection of problems in specific procedures and basic use cases (e.g., logging in, creating a new account, doing password resets).
Because automated tests can be run constantly or at intervals, testers can save time and effort on repetitive activities by automating web application tests. By relieving testers of these time-consuming chores, they may devote their attention to exploratory testing and other tests that require a human perspective.
Still, automation should not be viewed as a plug-and-play technology that eliminates the need for human participation. Effective automation necessitates a solid understanding of the programmer under test as well as an “automation first” approach on the part of testers.
What are the things you can automate?
Depending on your business goals, you can automate a variety of test cases.
More and more aspects of the life cycle are being automated these days, but you should pick the ones that best suit your testing team’s skills.
These are the types of web application tests that can be automated:
From the perspective of the end user, functional testing ensures that functionality described as part of the software requirements performs as intended. It is general knowledge that allowing the end-user to utilize the product is the test technique that discovers the most defects.
Even after unit, integration, and performance tests have passed, a single end-user can cause the entire system to crash in minutes. This frequently occurs when a user does something that the developers did not anticipate.
Automating tests in accordance with the requirements will guarantee that the web application functions properly. Functional test automation, on the other hand, cannot completely replace the human perspective. To offer a great user experience, you should constantly supplement your automated test cases with exploratory testing.
“Repeated functional testing” is how regression testing is defined. It’s used to ensure that a program’s functionality remains intact after sections of it have been changed with new code or configuration. Regression testing, for example, ensures that old software features continue to function as intended when new features are added.
To test software that has been altered or updated, automated regression testing use computer-based tools and methodologies. An automated process enables the creation of automated systems that execute all regression tests at predetermined intervals, such as daily or weekly, and report any failures.
When regression testing is automated, you can run through simple scenarios and evaluate a range of changes quickly and reliably to receive instant feedback. As a result, testers have more time to focus on product innovation or manual study of more rare scenarios that demand more care.
Cross-browser testing ensures that your online application works as intended across a variety of browsers, on both desktop and mobile devices.
This is critical because browsers are updated often, so your application may not perform as intended in your target browsers by the time you’re ready to launch it.
Furthermore, users may be using an ancient operating system while using the most recent browser version. As a result, automating crow-browser testing ensures that your online application remains compatible with the specified versions of operating systems, browsers, and devices.
Performance testing, such as stress and load testing, assures that a web application can withstand high user loads for lengthy periods of time. Because manually achieving the required stress conditions or load level would be impossible, automation is critical in demonstrating that your application can operate in any situation.
Best techniques for automating web app testing
Make sure you have a test automation strategy in place before you begin automating your web application tests. Before you begin automating, keep the following in mind:
* What are your web application’s special requirements?
* What processes do you want to automate?
* Which test automation technology is best for your needs and objectives?
* How much upkeep will automation necessitate?
Always start small and then scale up your automation efforts once you’re comfortable. Nobody wants to end up with hundreds of unmaintainable automated test cases.
Make sure you don’t get caught in the ‘test automation paradox,’ where test automation was expected to make software development more efficient and free up resources, but instead it introduces a slew of additional, expensive chores and never-ending maintenance.
Successful web application testing necessitates efficient test automation methods, clear team communication, a successful strategy, and an automation technology that does not hinder but rather empowers testers.
