Our Case Studies
Frequently Asked Questions
-
Why is API automation testing critical in modern applications?
APIs connect services, devices, and platforms. Testing them ensures backend stability, prevents integration failures, and guarantees accurate data exchange—without relying on slow, manual checks.
-
Do you test both internal and third-party APIs?
Yes. We validate your in-house APIs and also test external integrations like payment gateways or CRMs—ensuring end-to-end reliability across internal and partner ecosystems.
-
How do you handle authentication and security in tests?
We manage OAuth tokens, headers, and encryption securely during test runs. Our test suites simulate real-world access patterns without compromising API security.
-
What tools do you use for API automation?
We use Postman for functional testing and Rest Assured or Karate for code-based tests—tailored to your stack and suited for scaling across hundreds of endpoints
-
Can you help us set up API test automation from scratch?
Yes. We define scenarios, create scripts, integrate tests into CI/CD, and maintain them over time—ensuring seamless coverage even if you’re new to API testing.

Software Testing Types: The Ultimate Cheat Sheet with Real Examples
Navigating the world of software testing can feel like learning a new language. With dozens of methodologies, techniques, and specialized terms, teams often struggle to answer fundamental questions: Which test should we run? When should we run it? What value does it actually deliver? This confusion can lead to critical gaps in quality, wasted effort on redundant […]
Chaos Testing Guide: Build Resilient Systems Through Failure
In the architecture of modern software—a sprawling ecosystem of microservices, cloud dependencies, and distributed databases—failure is not a question of “if” but “when.” Networks partition, third-party APIs throttle, data centers experience outages, and new code deployments introduce unexpected side effects. Traditional reliability testing, which often assumes a controlled, predictable environment, is inadequate for this reality. It […]
