Web Application Testing: Best Practices for Faster, Smarter QA

Web application testing: slow, inefficient, fiddly? It doesn't have to be.

Sure, web apps have some unique properties to consider from a QA point of view.Once, this might have been something you just needed to put up with - a givenfact of testing this type of software which meant there were always going tobe some slowdowns.

That's not the case anymore. With the right approach, and a little help fromslick, AI-enabled modern web testing tools, web application testingdoesn't have to be an obstacle. In fact, do it right andit might just become a key strategic differentiator for your team.

Ready to say goodbye to hours of manually running browser and UI tests, orconstantly maintaining test scripts for evolving UI features? Here's how theright approach to QA testing for web apps turns traditional QA into your secretdeployment accelerant.

Why Web Applications Are Trickier To Test

From a top level perspective, web app testing strategies aren't that differentto testing other types of software. No matter how you run your QA processes andwhat you're testing, the overall goals of your QA won't change.

However, what you need to remember is that web apps have requirements,behaviors, and dependencies that other software doesn't. This throws up a fewunique concerns that add time and complexity to web application testing.

Unique considerations for web app testingWhatWhyBrowser compatibilityWeb apps need to work consistently across different browsers, on both desktop and mobile devices.Network connectionWeb apps depend on the internet, so you should test across stable/unstable connections, and (where relevant) cache and offline scenarios.Responsive designWeb apps need to display correctly on a wide range of screens and devices, across both portrait and landscape orientations,SecurityWeb apps are innately susceptible to online cyber threats, so need in-depth security testing for XSS, CSRF, SQL injection, and HTTPS enforcement.Client/server communicationThe need to test client-side frontend and backend, and how they interact with each other, adds an extra layer of complexity.

�But With Challenge Comes Potential

It's not all bad news! Consider that:

• Once your code is ready to deploy, updating web apps can be much quicker than native apps. You can push updates instantly with no user input and there's no external approval process (e.g., via the App Store) - deployments take minutes, not hours or days.
• Every single organization that releases web apps has these issues. Your competitors' QA teams also need to test their products across different browsers and navigate exactly the same issues as you do.

Web apps have real potential for fast, adaptable code deployment. If you canimplement a set of processes and best practices that allow you to navigate thesechallenges and release better code, quicker, you're at a major advantage to yourcompetitors.

AI: The Essential Tool For Modern Web Application Testing

Previously, engineering teams havefaced a tough choice: settle for slow,manual QA processes or commit upfront resources to automating tests of variouscomplexity for long-term efficiency benefits.

Either way, slowdowns and bottlenecks are guaranteed, right?

Modern web testing tools remove this issue from the table altogether and replaceit with something far better: intelligent, automated QA that expands testcoverage whilst minimizing the time you spend on it.

Codeless test automation and a range of otherfeatures, like the ability to run parallel tests, offer an instant boost to thespeed at which you can test, and the coverage you can achieve - but the benefitsdon't stop there.

AI tools can fundamentally change how you structure your QA testing for webapps. To make the most of their potential, follow our five best practices forefficient, seamless automated QA that creates great products.

5 Best Practices For Web Application Testing With AI Tools

1. Expand Your Cross Browser/Cross Device Testing Capability

You want to make sure your web app runs as well on Chrome as on Firefox - andlooks just as good on a mobile browser as a desktop one.

AI-based UI testing tools combineautomated functional andvisual tests to understand how your app behaves across browsers and devices.Where previously you'd need to strictly allocate resources to testing the mostrelevant options for your user base, the speed AI brings means you can cast amuch wider net.

Look for solutions that:

• Validate browser compatibility in CI to avoid code breaking in untested browsers
• Run cross browser or device tests in parallel to speed up development cycles
• Automatically record and screenshot visual tests

Can AI Tools Simulate Touch Events?

We'd say that AI simulations work perfectly for most of what you want to test.This includes:

• Taps
• Long presses
• Swipes and scrolls
• Pinch/zoom

Currently, simulated environments sometimes struggle to recreate touch pressure,multi-touch points, or other nuanced gestures. Another issue is that mobileemulators simulate screen size and input type pretty well, but don't account forCPU/GPU performance, touch latency, or browser quirks.

Our recommendation: use AI tools to automate the bulk of your cross browser andcross device testing - but keep some resources for edge cases and real deviceperformance analysis.

2. Shift Everything Left, Especially Security Testing

'Early and often' offers many advantages for your test suite in general. If youtest earlier, potential bugs are easier to identify and cheaper (in developmenthours) to fix.

AI tools facilitate Shift Left testing by:

• Making it easier and quicker for engineers to test their own code, thanks to natural language processing powered no-code test editors.
• Generating test cases automatically based on the application's previous behavior patterns for hyper relevant testing.
• Removing the inefficiencies associated with separate engineering and QA teams
• an engineer presses a button, tests the code, and uses recommendations from an AI agent to fix issues - no lengthy meetings needed.

For web apps in particular, this is a great opportunity to introduce securitytesting earlier on in the development process. Traditionally, security testingis one of the last steps to be completed before shipping code. The pressure thiscreates can lead to:

• Delayed releases as key vulnerabilities are identified last minute, when they are most complicated to fix.
• Human error caused by pressure to meet release schedules - with missed or poorly-fixed vulnerabilities causing significant security issues further down the line.

Shifting security testing left removes this pressure, and promotes a proactiveapproach to web app security across the development process. Increasing yoursecurity team's visibility over early-stage development - for example by usingAPIs to integrate security into developer toolsets to identify problems from theget-go - resulting in better, more secure code, faster releases, and fewerpressure-driven human errors.

3. Automate Your Test Maintenance

Web app testing, UI testing for web applications in particular, can generate asignificant test maintenance workload. This is because test selectors can breakif the DOM structure shifts or CSS classes change. If you update your UIregularly, this can become a frustrating time drain.

Whether you're an engineer or a QA professional, you'll be pleased to know thatmodern web application testing tools can automate those tedious hours of testmaintenance using AI.

If you're using a tool like Momentic, the AI can dynamically locate elements atruntime while being flexible to UI and DOM changes. Plus,auto-healing featurescan automatically fix failed tests by suggesting step changes - so you saveyourself hours of work and drastically reduce the likelihood of unreliableresults due to flaky tests.

4. Focus Human Input Where It Really Matters

Follow the browser testing best practices above, and you'll find yourselfcompleting the bulk of your web application testing in record time.

Now that you're not constantly chasing deadlines or fighting bottlenecks, youcan deploy your human resources where they can really make a difference.Obviously, from an engineering point of view, it feels great to have more spaceto work on new code - but there's plenty you can do testing-wise too!

Human-led behavior, accessibility, and usability tests can add real value toyour product - and you can also dedicate more time to your most complex testcases, which may still need manual support.
