Software Testing & Quality Assurance

Integration Testing

Testing of the interfaces between your modules, services, databases and third-party systems, catching mismatched data, contract breaks and failure handling problems early.

Overview

Why it matters
for your business.

Individual components can each pass their own tests and still fail together. A payment gateway returns an unexpected status, a microservice renames a field, a message queue delivers the same event twice. Integration testing targets these seams. We map how your modules and external services communicate and test each interaction, including errors, timeouts and retries.

Where third parties such as payment, SMS or GST services cannot be called freely, we use sandboxes, mocks or contract tests to simulate them reliably. Tests run in an environment that mirrors production configuration. We pay particular attention to data mapping, idempotency and what happens when a dependency is slow or unavailable.

  • Integration map of internal and external interfaces
  • Interface test cases including error scenarios
  • Mocks and sandboxes for third-party services
  • Consumer-driven contract tests
  • Timeout, retry and failure handling verification
  • Integration defect and risk report

Outcomes

What changes
for your business.

Ideal for

  • Microservice-based platforms
  • Apps relying on payment and KYC providers
  • Enterprises integrating ERP with external systems

Fewer interface surprises

Mismatched fields, formats and status codes are found before they cause failed transactions in production.

Resilient failure handling

Verified timeout and retry behaviour helps your system degrade gracefully when partners have outages.

Safer independent releases

Contract tests let teams change services without unknowingly breaking the systems that depend on them.

FAQ

Common
questions.

Something else on your mind? Ask us directly.

Can you test integrations with payment gateways like Razorpay?

Yes, using the provider’s test or sandbox mode, which simulates success, failure and pending outcomes without real money. We also verify webhook handling, signature validation and reconciliation logic, which are common sources of payment defects.

How is this different from API testing?

API testing validates individual endpoints in depth: inputs, outputs, errors and security. Integration testing focuses on how components work together across those interfaces, including data flow between systems, message handling and behaviour when a dependency fails.
