Functional Testing
We assess each feature of your web application against the predefined functional requirements and find system aspects that don't fulfill operational metrics or deliver intended results.

Scope
What does a web application testing service actually cover?
Functional correctness is the smallest part of it. The failures that reach production are usually about environment, state and integration rather than logic.
A web app testing engagement covers the functional paths, but the defects that survive to release tend to live elsewhere: a form that works in Chrome and silently drops a field in Safari, a layout that holds at 1440px and truncates a price at 360px, a session that expires mid-checkout, an API contract that changed without the front end being told. Coverage means cross-browser and cross-viewport verification, API and contract checks beneath the UI, authentication and session-state paths, and the error branches nobody demos.
Accessibility belongs in scope rather than in a separate audit at the end. Testing with a keyboard and a screen reader surfaces genuine defects — focus that vanishes, controls with no accessible name, state changes announced to nobody — and finding those during development costs a fraction of retrofitting them after a complaint.
Balance
How much web application testing should be automated?
Enough that every release is regression-checked without a human, and no more than the suite can keep trustworthy.
Automation earns its place on the checks you run on every build: the critical journeys, the API layer, the cross-browser smoke pass. Those are stable, repeatable and expensive to repeat by hand. The moment a suite grows past what the team can keep green, it stops being a safety net and becomes a source of noise — and a suite people routinely re-run until it passes is worse than no suite, because it launders failures into passes.
Exploratory testing stays human permanently. A script verifies what somebody already thought of; a tester following a hunch through an unusual sequence is how the unanticipated defects surface. We size the automated pack against your release cadence and keep deliberate human time for the parts scripts are bad at.
