12 Bug Exterminating Techniques for Your Toolbelt
1. Physical Devices Uncover What Emulators Miss
Emulators only emulate hardware and software environments. So they miss many mobile bugs that only surface on real smartphones and tablets.
For the most accurate and extensive testing, leverage real iOS, Android and Windows Phone devices – across various makes like Samsung, Apple, HTC and more. Cover multiple models, OS versions, screen sizes and browsers.
Services like BrowserStack and LambdaTest give instant virtual access to thousands of real mobile devices in the cloud. So even the smallest dev teams can test like the big enterprises!
According to research from SciTechnol, real devices catch 19% more defects than emulators on average. Don‘t let device fragmentation bugs slip through the cracks.
2. Ensure Pixel Perfect Responsiveness
Sites with elements that overlap, stack weirdly or get cut off frustrate users. So rigorously resizing windows and simulating smartphones, tablets and more is critical.
Elements should rearrange and resize appropriately as screens contract or expand. Testing responsiveness across multiple viewports catches bugs in advance.
3. Cross-Browser Testing Hits Browser Peculiarities
Different browsers interpret code differently thanks to discrepancies with JavaScript, CSS and HTML5 handling. So thoroughly test across browsers manually and via automated tools.
Common culprits for cross-browser issues include style rendering, video playback, and input widgets. Hit various browser edge cases to catch this tricky category of bugs.
4. Crushing Site Speed Defects
Here‘s an alarming stat for you – according to Akamai, each additional second of load time reduces conversions by 7%. Slow performance directly hurts your bottom line!
So rigorously testing site speed using online tools is mission critical. Pay attention to page load times across desktop and mobile to catch lags or bottlenecks.
I also recommend throttling connections to simulate real world poor network conditions during testing. This triggers bugs that only surface on slower connections, helping address defects before customers experience them.
As a rule of thumb, target under 2 second load times as an optimal benchmark to aim for. Need help accelerating your site? Check out my complete guide to web performance optimization.
5. Review Mobile Friendliness
With mobile internet usage now exceeding desktop, delivering great mobile experiences is imperative. Failing to fit content to smaller screens damages usability and conversions.
So thoroughly test that all elements render properly when minimizing screen size. Also verify that Google sees your site as mobile-friendly using tools like Google Mobile-Friendly Test.
Fix any flagged issues regarding tap targets, text size, viewport setup and more. Google specifically highlights mobile-friendly responsive sites in search results – so don‘t leave easy conversions on the table!
6. Plug Broken Links That Frustrate Visitors
Few things frustrate visitors more than clicking a link to find a broken video or dead webpage. Broken elements also damage site crawlerability for search engines.
So methodically crawl every page to validate images, links, videos and more work correctly. Eliminate anything directing to 404 errors or unavailable content.
This smooths user experience while improving organic visibility – it‘s a win-win for higher conversions.
7. Security Testing Safeguards Customer Data
Security exploits like SQL injection or cross-site scripting (XSS) attacks put customer data at risk. Even worse – data breaches directly damage brand reputation and trust.
That‘s why continuously security testing your website is no longer optional – it‘s a must. Utilize vulnerability scanners and conduct penetration tests to catch flaws before hackers can exploit them.
Pay special attention for common attack vectors like:
- SQL Injection – improperly filtered user input allows running destructive SQL database queries
- XSS Attacks – unencoded user input gets executed as JavaScript in the browser
Also research the OWASP Top 10 guide detailing the most critical web app vulnerabilities open to exploitation.
Stay on top of fast-evolving threats before customers pay the price!
8. Enable Access for Users of All Capabilities
Having an accessible site expands your audience reach by enabling those with disabilities to easily use your website.
Make sure your site complies with web accessibility standards like WCAG 2.1 that specify criteria for text contrast, screen reader capability and more. Conduct automated accessibility scans using tools like aXe or WAVE to catch defects.
Pay special attention to properly structuring headings, alt text for images, navigable site elements via keyboard only, and sufficient color contrast.
Building an inclusive site for users of ALL capabilities future-proofs your presence while opening up new conversion potential.
9. Usability Testing Catches Confusing Elements
Unlike machines, real people bring unpredictable perspectives. So directly observing actual visitors trying to use your site reveals pain points impossible to predict otherwise.
Watch for areas of confusion, too-small tap targets on mobile, or confusing calls to action during usability testing. Then refine any elements causing hesitation or problems based on user feedback.
According to research by Nielsen Norman Group, a stunning 95% of issues are caught by testing with just 5 users. So even minimal usability testing efforts pay huge dividends towards a smooth, frustration-free visitor experience.
10. Exploratory Testing Triggers Unexpected Defects
Unlike scripted tests, exploratory testing takes an unpredictable, ad-hoc approach to using features. Testers poke around trying different workflows to mimic real world usage.
The goal is triggering unexpected edge case bugs outside defined happy paths. So throw weird combinations of data at forms, rapid-click elements before previous actions complete, sequence steps out of order – anything to reveal corner case issues.
Deeply explore all site functionality through this unscripted, freewheeling approach to maximize bug yields.
11. Leverage Beta Testing to Catch Pre-Launch Bugs
When preparing to launch major new features, limited beta testing is invaluable. Grant early access to real users in return for feedback on new functionality.
By beta testing changes at smaller scale, bugs can get addressed BEFORE unleashing issues to your full visitor base. 80% of software bugs originate from just 20% of the code – leverage beta users to find your trouble hotspots!
12. Debugging Tools Pinpoint Tricky JavaScript Bugs
Modern web apps rely heavily on JavaScript for complex interactions. But JavaScript‘s asynchronous nature makes it notoriously difficult to debug for developers.
Luckily, dedicated JavaScript debuggers like BrowserStack Live efficiently hunt down JS errors or layout issues. Finding front-end code defects then streamlines fixing them for you.
Debugging tools add invaluable precision when tracking down elusive, browser-specific JavaScript bugs. Add them to your haunted house of horror tools for exterminating bugs!
