What Is Baseline Testing? Meaning, Examples & Use Cases (2026)
Baseline testing compares current test results against an approved reference from a previously validated version – not to find bugs in isolation, but to detect whether something changed unexpectedly. The most reliable approach is record-replay: capture real application behavior from a working version, then replay against each new release in CI. Keploy applies this directly…

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…

Why I Switched from Rest Assured to Keploy for Microservices Testing
If you’ve been using Rest Assured for API testing, you know how powerful it is. The syntax looks simple and easier to understand, but things get interesting when you have to write test cases and mocks for a microservices application that has more than 2 services. Key Takeaway: Keploy replaces REST Assured’s manual Java test…

What Is TDD? A Complete Guide to Test Driven Development
Modern software development moves fast. Delivering bug free code is no longer just a goal. It is a requirement. But how do you ensure your code works before you even finish writing it? The answer is TDD, or Test Driven Development. In this guide, we will answer what is TDD, explore how it transforms the…

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…

A Complete Guide to CI Testing: Benefits, Tools & Workflow
CI testing is the automatic running of tests every time code is committed to a shared repository, so integration issues and regressions surface immediately instead of piling up. Teams keep the mainline releasable by wiring fast, reliable suites into every build. Keploy suits this well, producing API tests from real traffic and slotting straight into…

SOAP UI vs Postman for API Testing: Which Should You Use?
Developers and Quality Assurance (QA) teams utilize many different API testing and validation tools to help them simplify the processes of testing, debugging, and validating APIs in the increasingly API-centric world of software development. Modern teams often combine End-to-End Testing with API-level testing to ensure full workflow reliability. Key Takeaway: While SoapUI and Postman both…

End-to-End Test Automation: How It Works and Why It Matters
One of the most critical ways to validate real user journeys across any application is through end-to-end testing. Modern software stacks have grown so distributed that manual E2E testing grows increasingly hard to maintain and nearly impossible to scale. This is where automation in end-to-end testing helps engineering teams with the reliability, speed, and confidence…

How to Build an Automation Framework for API First Testing
As modern applications grow more complex and API-driven, maintaining test stability becomes increasingly challenging. Many QA teams struggle to manage scattered test scripts and inconsistent environments, leading to inefficiency and missed defects. The real solution lies in adopting a structured automation framework that brings order, scalability, and speed to the testing process. In an API-first…

What Is an API Endpoint? (Complete Guide for Developers & QA Testers)
An API endpoint is a defined URL or path where an API accepts a request from the client, such as a web app, mobile app, automation script, or AI agent, and sends back a response. It serves as the official communication point between the frontend and backend. In other words, if an API is a…
