Compatibility Testing
Compatibility Testing ensures that your digital product delivers a consistent and smooth experience across various devices, browsers, screen sizes, and operating systems. It checks how your app behaves in different user environments—so no matter where or how someone accesses it, it performs as expected.
At Tek Leaders, we test your application on a wide range of configurations—covering mobile, desktop, tablets, modern and legacy browsers, and different OS versions. Our goal is to identify inconsistencies early, fix layout and functionality issues, and make sure your users get a seamless experience everywhere.
Why Compatibility Testing?
Your users access your product from all kinds of devices and browsers—and each one can behave differently. A feature that works perfectly on Chrome might break on Safari. A layout that looks great on desktop could be clunky on a mobile screen. Compatibility Testing helps you avoid these headaches by making sure your app looks and functions the way it should, no matter the platform. It improves accessibility, reduces user frustration, and protects your brand reputation by ensuring your digital product is dependable and polished everywhere it’s used.
Our Compatibility Testing Services:
Define the Compatibility Scope
We start by identifying which devices, browsers, and operating systems your users are most likely to use—based on analytics and target market.
We define the right combination of desktop, mobile, tablet, and browser versions (modern and legacy) to include in the test matrix.
We set standards for what “working as expected” looks like—from layout consistency and UI responsiveness to feature functionality and user input behavior.
Set Up the Testing Environment
We prepare physical devices, emulators, simulators, and browser stacks to mirror real-world usage scenarios.
We use platforms like BrowserStack or Sauce Labs to test efficiently across a broad range of environments—without the hardware hassle.
We strike a balance between manual tests (for visual/UI checks) and automation (for speed and repeatability) based on test complexity.
Execute Compatibility Tests
We validate your application’s appearance and behavior on Chrome, Firefox, Safari, Edge, and others—ensuring smooth experiences on each.
We check usability and responsiveness across smartphones, tablets, and desktops of varying screen sizes and hardware capabilities.
We test the app on multiple versions of Android, iOS, Windows, and macOS to catch OS-specific rendering or behavior issues.
Identify and Report Issues
We identify issues like broken elements, misaligned layouts, or overlapping text that affect user experience across platforms.
We highlight platform-specific functionality problems—such as forms, buttons, dropdowns, or media players not working as expected.
We document issues clearly, with screenshots, device/browser details, and steps to reproduce—making it easy for your dev team to resolve them.
Optimize for Every User
We work alongside your development and design teams to adjust styles, scripts, or platform-specific code for maximum compatibility.
After fixes are applied, we re-test across affected environments to confirm everything works consistently and previous functionality is intact.
We provide guidance on maintaining compatibility as new OS and browser versions are released—so your product stays reliable over time.
