System integration & API testing
Passing unit tests don't prove your components work together. We test the interfaces, APIs and end-to-end flows that connect your systems.
The challenges this solves
Our APIs fail in production
Frequent API failures hurt reliability and user trust.
Third-party integrations worry us
We connect to complex outside services and aren't sure they are secure.
Components break when combined
Each module passes on its own, but end-to-end flows fail.
What we deliver
- Interface tests between components and the system
- Full integrated-system tests in a simulated production environment
- Cross-server scenarios in client-server and web service applications
- End-to-end scenarios across multiple applications
- Interoperability testing with other standards-based solutions
- API validation, functional and integration testing against business requirements
- API security testing, including penetration and fuzz testing
- API reliability and performance testing under varying conditions
Systems and tools
- SoapUI
- JMeter
- Selenium
- Cucumber
- Jira
4 steps, clear deliverables

Plan
We build a test strategy and plan around your interfaces, APIs and data flows.
You receive: Integration test strategy and plan
- 02
Test interfaces
We create and run tests on the interfaces between components and the system.
You receive: Interface and API test results
- 03
Test the whole system
We run end-to-end tests on the integrated system in a simulated production environment.
You receive: End-to-end results and defect reports
- 04
Recommend
We report what failed and how to fix it.
You receive: Corrective action recommendations

Questions we hear most
Why is integration testing needed if unit tests pass?
Unit tests check modules alone. Integration testing confirms the combined components meet functional, performance and reliability requirements.
Do you test APIs?
Yes. We cover API validation, functional, integration, security, reliability and performance testing.
What will we receive?
You get a tailored test strategy and plan, test results, and recommendations for corrective action.
Can integration tests be automated?
Yes. Reusable automated scripts let us test earlier and faster and cut manual testing errors.
Make sure your systems work together
Tell us which systems and APIs you connect. We will plan integration coverage across them.
