Integration Testing Services

Continuous Testing

Our continuous integration service automatically runs integration tests on any new releases of code to immediately detect errors.

Manual & Automated

Our software testing team are qualified in both manual and automated testing, giving you freedom over your tailored service.

Reduced Risk

Reduce the likelihood of integrated-related user issues after your software has been deployed to your users.

Save Money

Finding bugs earlier can make them much cheaper to fix, lowering the overall cost of your development lifecycles.

Save Time

Integrated testing streamlines the entire process of testing individual components. Outsourcing frees up valuable time for your internal teams.

Simulate User Actions

Our testing approaches allow us to simulate real user actions and determine if your software interacts with other systems as it should.

Ensure Your Systems Work Seamlessly

As businesses adopt complex digital systems, seamless interaction between applications, APIs, third-party platforms and internal systems is essential. Integration testing ensures these systems work together efficiently, avoiding failures, inconsistencies and costly downtime.

PSP provides comprehensive integration testing services for UK membership bodies and businesses to guarantee smooth, accurate and reliable data flow across your software and systems.

What Is Integration Testing?

Unlike unit testing, which focuses on individual components, integration testing validates how different software modules, services and third-party systems interact with one another. By catching interface defects early, integration testing reduces production risks, improves system reliability and delivers a consistent user experience.

Our ISTQB-certified testers simulate real-world user scenarios to verify:

System Interaction Validation - We verify seamless communication between software modules, services, and third-party platforms.
Data Integrity Assurance - Our tests ensure accurate data transfer and synchronisation across systems.
End-to-End Workflow Testing - We simulate real-world scenarios to validate complete system workflows.
Compatibility Testing - We confirm interoperability with platforms like Salesforce, Stripe, SAP, and more.
API & Middleware Testing - We test APIs, web services, and message queues for reliability and performance.

Why Integration Testing Matters

Fragmented data and siloed systems lead to missed opportunities and poor customer journeys. Whether you're integrating a new CRM, connecting an eCommerce platform, or deploying a microservices architecture, integration testing ensures your technology stack functions as a unified solution.
