API Testing

Testing Solutions

Validate the Core of Your Architecture

In modern microservices architectures, the UI is just the tip of the iceberg. At ErikLabs, we validate the logic, reliability, and performance of your application’s backend before a single line of frontend code is written. With API testing, we ensure your services communicate flawlessly, handling data exchange with precision and security.

Our approach drastically reduces debugging time and ensures that your core business logic is robust and error-free.

Contract-Based

Shift-Left Logic Validation

We test business logic at the API level to identify bugs early in the development cycle. Our ``Shift Left`` approach catches integration errors and logic flaws before they become expensive UI problems.

Security & Compliance Checks

We integrate security directly into our API tests. We validate authorization logic, encryption standards, and schema compliance to ensure your data remains protected against vulnerabilities.

Comprehensive End-to-End Workflows

We go beyond simple endpoint checks. We chain requests to simulate complex, real-world user journeys, validating that your data flows correctly across multiple services and third-party integrations.

Resilient Mocking & Virtualization

We use advanced service virtualization to isolate dependencies. This allows us to test your APIs reliably even when third-party services or dependent systems are offline or unstable.

Frequently Asked Questions

Here’s everything you need to know about API testing.

1. Why is API testing faster than UI testing?

API tests bypass the browser, executing requests directly against the server in milliseconds, making them significantly faster and more stable than UI tests.

2. Do you support both REST and GraphQL?

Yes. We have extensive experience testing RESTful services, GraphQL endpoints, and SOAP architectures using industry-standard tools.

3. Can API testing help with security?

Definitely. We perform security checks at the API level, validating authorization logic, encryption, and protection against injection attacks.

4. How do you handle API dependencies?

We use advanced mocking and service virtualization techniques to isolate the API under test, ensuring reliable results even when dependent services are down.
