Quality, Security & Compliance

Functional & Integration Testing

We validate that every function of your software works as intended both independently and as part of a complete system through thorough functional and integration testing that ensures reliability and seamless workflows.

Why You Might Need Functional & Integration Testing

small blob

Features Not Working as Expected

We catch functional defects early to ensure every feature behaves exactly as defined in the requirements.

Modules Failing When Combined

Our integration testing ensures all components databases, APIs, services work smoothly together.

Frequent Breakages After New Changes

We perform regression testing to catch unintended effects caused by code changes.

Lack of Business Rule Validation

We verify your business logic across all scenarios to ensure process integrity and compliance.

Inconsistent Behavior Across Environments

We run tests across different staging and production environments to ensure consistent results.

Unclear Test Coverage

We define and document comprehensive test cases that align with functional specs and user flows.


Our Functional & Integration Testing Process

Requirement Analysis

We analyze functional specs, user stories, and business rules to define test coverage.
