Integration Testing

Find broken integrations in staging, not your incident channel

We test the connection points most QA plans skip — APIs, microservices, message queues, third-party connectors, and legacy system interfaces — so a contract change or a dropped event gets caught by a test, not a downstream team.

Who this is for

Engineering teams running a microservices or service-oriented architecture with API, event, or legacy-system integrations that don’t yet have dedicated integration test coverage.

Especially useful if your integration bugs usually surface as a message from another team, not a failed pipeline.

What you get

  • 20–35 automated integration test cases covering your highest-risk service boundaries — APIs, message queues, or legacy interfaces, scoped at kickoff
  • Consumer-driven contract tests (Pact) between 2–3 service pairs you flag as highest risk, with a Pact Broker set up for ongoing verification
  • Service virtualisation (WireMock or Hoverfly) for dependencies that are slow, flaky, or unavailable in staging
  • A dependency and integration map documenting every service boundary, API contract, and message topic in scope
  • Automated suite wired into CI (GitHub Actions, Jenkins, or GitLab CI) running on every pull request, plus a nightly full-stack run
  • HTML test reports linking each failure to the specific integration boundary and contract clause violated
  • A 60-minute handover session walking your team through the suite, the contract setup, and how to extend it
  • 2 weeks of post-handover support for flaky tests or environment issues

What's not included

Scoped this way on purpose, so the estimate stays accurate and nothing shows up as a surprise mid-engagement.

  • Full performance/load testing of the integration layer — available as a separate, scoped engagement
  • Coverage of third-party services or partner APIs we can’t reach from a sandbox or staging environment
  • Ongoing contract governance across teams beyond the services agreed at kickoff
  • Ongoing maintenance after the 2-week support window — available separately as a retainer

Timeline & process

  1. 1
    Week 1

    Dependency mapping & scoping

    Map service boundaries, APIs, and message topics, and agree which integration points matter most.

  2. 2
    Week 2

    Contract & test design

    Formalise contracts (OpenAPI, Pact, or AsyncAPI) and design test scenarios for happy paths, error boundaries, and failure injection.

  3. 3
    Week 3

    Automation & CI wiring

    Build the suite, set up service virtualisation where needed, and wire tests into your CI pipeline.

  4. 4
    Week 4

    Handover & stabilization

    Fix flaky tests, hand over the dependency map and reports, run the walkthrough call, and start the support window.

What we need from you

  • Access to a staging environment where the services under test can actually talk to each other
  • API documentation, OpenAPI/AsyncAPI specs, or 30 minutes with the engineers who own each side of the integrations in scope
  • Test credentials and any sandbox access needed for third-party connectors
  • One walkthrough call with both producer and consumer teams before we start

Proof, not promises

Find out which of your integrations don’t have test coverage

Twenty minutes, no slide deck. Send us your architecture diagram and we’ll tell you which service boundaries carry the most risk.
