Stateful vs Stateless: A Developer’s Real-World Guide (2026)
Why do some bugs only appear after deployment, even when tests pass locally? Early in my backend work, I kept hearing discussions around stateful vs stateless. It felt academic at first, but once I started dealing with scaling issues, flaky tests, and production bugs, I saw how much this decision actually matters. This article is…

Penetration Testing Services to Strengthen Your Security and Reliability
Modern technology (APIs, Microservices, Cloud Platforms, Mobile Apps) is rapidly changing and becoming a target for attackers as they continue to advance and become more sophisticated. Organizations use penetration testing (a form of ethical hacking) to identify weaknesses in their systems and address them before they can be taken advantage of. Keploy supports organizations’ application…

What Does Extensible Mean? A Complete Guide with Examples and Use Cases
Extensibility is conceptually found in the areas of technology (such as Software Development) and System Design. The term extensibility may seem abstract to someone with no previous background in the field; in particular, when you hear phrases like: “Extensible Software”, “Extensible Architecture”, “Extensible API” or “Extensible Testing Tools”, it could be difficult to understand exactly…

How to Automate API Testing (Step-by-Step Guide for Beginners)
API automation testing uses scripts and tools to validate APIs automatically instead of testing them manually. Automated suites send requests, assert on responses, and run continuously in CI/CD to catch regressions on every change. Tools like Postman, REST Assured, and Keploy, which generates tests from real traffic, make this faster to build and maintain. APIs…

Generative AI Testing Tools: The Next Evolution of Test Automation
Generative AI testing tools use large language models and machine learning to automatically create test assets (test cases, test data, mocks, and stubs) from how your application actually behaves. Unlike conventional AI testing tools, which mostly refine or prioritise the tests you already have, they generate genuinely new ones and keep them current as the…

AI testing: a complete technical guide to intelligent software quality
AI testing uses machine learning, NLP, and computer vision to generate and maintain tests, replacing static scripts with models that adapt to how the application behaves. Self-healing selectors and predictive selection cut the overhead that breaks traditional automation with every UI or API change. Keploy acts as an API testing agent, generating and validating tests…
