Web, Mobile & API Testing

The problem

A feature that works perfectly on your development machine can behave differently on another browser, an older device, a smaller screen, or when the API it depends on returns something unexpected. Without dedicated coverage across these surfaces, compatibility issues and integration bugs are usually discovered by users - on the device or browser your team happened not to test on.

What’s at risk without it

• Layout, functionality, or performance issues on specific browsers or devices
• API contract mismatches between frontend and backend
• Broken integrations when a third-party or internal API changes
• Inconsistent behavior across iOS/Android or desktop/mobile web
• Untested error handling when an API call fails or times out

What we test

• Core functional flows across major browsers and versions
• Responsive and mobile web behavior across device sizes
• Native and hybrid mobile app functionality (iOS/Android)
• REST/API request and response validation, including error and edge cases
• Authentication, authorization, and session handling across surfaces
• Integration points between frontend, backend, and third-party services

Our approach

We map your product’s supported browsers, devices, and API surface, then design test coverage that reflects real usage rather than testing every possible combination indiscriminately. API testing is treated as its own discipline - validating contracts, status codes, error handling, and data integrity - not just checked incidentally through the UI.

1. Define supported browser, device, and API matrix
2. Functional test design per surface (web, mobile, API)
3. Execution across the defined matrix, with defect logging
4. API-level validation of requests, responses, and error handling
5. Regression coverage ahead of releases

Deliverables

• Cross-browser/device compatibility report
• API test results with request/response validation
• Defect reports with reproduction steps and evidence
• Prioritized list of compatibility and integration issues

Suitable for

Products with a meaningful web or mobile footprint that need confidence across real-world browsers and devices, and any team with API-driven architecture that wants integration issues caught before they reach the frontend.

FAQs

Do you test native mobile apps, mobile web, or both?

Both, depending on what your product ships. We scope the test matrix to match your actual supported platforms.

How do you decide which browsers and devices to cover?

Based on your real usage data where available, or a sensible default matrix of current major browsers and common device sizes when analytics aren’t available yet.

Can API testing be done independently of the frontend?

Yes. we test APIs directly against their contracts (requests, responses, status codes, error handling) rather than relying solely on what’s visible through the UI.
