Web testing services
We test web applications and websites end to end: features, browsers, devices, speed, security and accessibility. You get every defect with steps to reproduce.

What is web testing?
Web testing checks web applications and websites across browsers, operating systems and devices, so they work the same way for every user.
Unlike desktop application testing, web testing has to deal with browser compatibility, responsive design, network conditions and security threats. It covers everything from functional workflows and page rendering to performance under load and accessibility.
Web testing types
| Test type | Description | Focus area |
|---|---|---|
| Functional testing | Every feature works as specified: forms, navigation, search, checkout and user authentication. | Features |
| Cross-browser testing | The same look and behaviour in Chrome, Firefox, Safari, Edge and any older browsers you support, on each operating system. | Compatibility |
| Performance testing | Page load times, server response, Core Web Vitals and behaviour with many users at once. | Speed |
| Security testing | Vulnerabilities such as XSS, SQL injection, CSRF, broken authentication and data exposure. | Protection |
| Accessibility testing | WCAG conformance, so people using screen readers, keyboards and other assistive technology can use the site. | WCAG |
| Usability testing | Whether users can find their way and finish their tasks, through task-based sessions and heuristic review. | UX |
Each type has its own page: functional, performance, security, accessibility and usability testing.
Browser coverage matrix
We pick the browsers and versions from your own analytics, so coverage follows where your users actually are.
| Browser | Engine | What we watch for |
|---|---|---|
| Chrome | Blink | The baseline most teams develop in, so defects elsewhere show up as differences from it. |
| Safari | WebKit | Layout, date input and media differences. On iOS almost every browser still uses WebKit; other engines are allowed only in some regions, such as the EU. |
| Firefox | Gecko | CSS and form rendering differences, and stricter handling of some web APIs. |
| Edge | Blink | Mostly matches Chrome; enterprise policies and older versions are the usual risk. |
Testing tools
Selenium
The long-established automation framework for cross-browser testing, with bindings for many languages.
Playwright
A modern automation library with auto-wait, parallel runs and a built-in trace viewer.
Cypress
End-to-end testing that runs in the browser, with automatic waiting for elements.
BrowserStack
We use BrowserStack to test on real browsers and devices, for coverage beyond the devices on the desk.
Tools we work with, in your accounts or ours, chosen to fit your stack and your team. More on test automation.
Responsive testing
Desktop
1200px and up. Full-width and multi-column layouts, hover states and keyboard navigation.
Tablet
768px to 1199px. Touch, orientation changes and layouts that adapt between desktop and mobile.
Mobile
320px to 767px. Touch gestures, viewport scaling, hamburger menus and performance on slower networks.
Based on W3C web standards. Native apps are covered on mobile app testing.
How BetterQA does web testing
We test the journeys that make you money first, on the browsers and devices your analytics show, and keep a regression suite so the next release does not undo the last one.
Engineers who test for a living
BetterQA, founded 2018, 50+ QA engineers. People plan and run the web testing and report what the results mean for your release.
Bugs you can act on
Every defect we find is written up in BugBoard, our own test management tool, or in your tracker, with steps to reproduce, the expected and actual result, and the environment.
A certified process
ISO 9001 for quality management and ISO 27001:2022 for information security. See our certifications.

Web testing: common questions
What is web testing?
Testing a website or web application for functionality, browser and device compatibility, performance, security, accessibility and usability before and after release.
What are the types of web testing?
Functional, cross-browser, performance, security, accessibility and usability testing. Most projects need several of them.
Which browsers should we test on?
The ones your users have. We read your analytics and usually cover the current Chrome, Safari, Firefox and Edge, plus any older versions with real traffic.
Do you automate web tests?
Where it pays: stable, repeated journeys go into an automated regression suite, while new and visual areas get manual and exploratory testing.
What does it cost?
The cost depends on the number of journeys, browsers and devices in scope. Our rate is €20-45 per hour. For ongoing work the first month is a trial, the first two weeks are complimentary if you are not happy, and after that it is 30 days' notice.
