Compatibility Testing

The modern software environment is fragmented across hundreds of browser versions, operating systems, device form factors, and integration configurations. Developers naturally test in their own preferred environment—and miss the failures that only occur elsewhere.

NextGen Coding Company's compatibility testing practice brings systematic coverage of the environments your actual users operate in—not just the environments your developers happen to use. Our QA engineers, trained at Columbia, Harvard, and Oxford with experience at Apple, Citi, and Wells Fargo, understand the browser rendering quirks, OS-level API differences, and hardware variations that produce compatibility failures.

We design compatibility test matrices based on your actual user base—analyzing your analytics data to identify the browsers, operating systems, and devices that represent the majority of your traffic—and we test systematically against that matrix. The result is a targeted testing program that covers your real user population, not a theoretical exhaustive list that would take forever to execute.

Compatibility testing services are priced based on the test matrix scope and depth of testing required.

**Compatibility Matrix Assessment** — Analysis of your user environment data and definition of an appropriate compatibility test matrix. Fixed fee.

**Pre-Release Compatibility Testing** — Execution of critical path tests across a defined compatibility matrix before a specified release. Priced based on matrix size.

**Comprehensive Compatibility Audit** — Full functional test suite execution across the complete compatibility matrix. Priced based on application complexity and matrix size.

**Automated Cross-Browser Testing Setup** — Implementation of automated cross-browser testing using BrowserStack or Sauce Labs, including CI/CD integration.

**Embedded QA via Developer Pod** — Dedicated US-based QA engineers providing ongoing compatibility testing as part of your development workflow.

NextGen publishes compatibility testing guidance for QA and development teams.

"Building a Cross-Browser Test Matrix: Analytics-Driven Coverage in the Post-IE World" — A guide to building a realistic browser compatibility test matrix using analytics data, covering tiering strategy, automated execution, and visual regression testing.

"Mobile Compatibility Testing: Real Devices vs. Simulators vs. Cloud Platforms" — A comparison of mobile testing approaches—physical device labs, simulators, and cloud platforms like BrowserStack—with guidance on when each is appropriate and how to combine them.

"Enterprise Browser Compatibility: Testing for Corporate Deployment Environments" — A guide to testing compatibility with enterprise browser deployments, including locked browser versions, security policies, and proxy configurations that are common in enterprise environments.

"Assistive Technology Compatibility: Testing Beyond WCAG Automated Checks" — A practical guide to testing compatibility with screen readers (NVDA, JAWS, VoiceOver), magnification software, and other AT, covering testing methodology and common failure patterns.

NextGen Coding Company is a US-based software development and testing firm whose QA engineers hold degrees from Columbia, Harvard, and Oxford and have tested software across the full spectrum of consumer and enterprise environments at Apple, Citi, and Wells Fargo. Our compatibility testing practice reflects practical experience with the real-world environment fragmentation that affects production software.

We design compatibility programs based on evidence—your actual user analytics—rather than theoretical exhaustive matrices that are too expensive to execute. This pragmatic, data-driven approach delivers maximum coverage for your specific user population.
