What Is Delta Testing? How It Works, Benefits & Examples (2026)
Delta testing validates only the changes between software versions, not the entire application, making it faster than full regression for frequent CI/CD releases. It runs after smoke testing gates the build, focusing specifically on what changed. For API-driven systems, Keploy supports this by recording real traffic from one version and replaying it against the next…

How to Use Copilot in Software Testing: A Practical Guide for Testers
Software testing is critical in assessing the quality of apps, testers oftentimes have to deal with limited resources when it comes to creating tests, as well as repetitively creating tests for all feature coverage. These factors lead to a significant reduction in both the speed of development and efficiency in the testing process. GitHub Copilot…

API Observability: What I Learned While Debugging APIs in Production
APIs rarely fail loudly. Most of the time, they break quietly while dashboards stay green. These silent failures are often the hardest to detect and the most damaging for users. I learned this while dealing with real production traffic. Everything looked normal until users started complaining. Let’s explore more about how this works. Why API…

DORA Metrics: Benchmarks, Tools & Strategies to Improve (2026)
DORA metrics are five research-backed measurements used by engineering teams to evaluate software delivery performance across two dimensions: throughput (speed) and stability (reliability). Most teams can track their numbers – the harder part is knowing which metric to fix first and what actually moves it. This guide covers 2026 benchmarks, proven strategies, and where automated…

Postman Alternative: The Best API Testing Tools to Use in 2026
A Postman alternative is any API testing tool that can replace Postman for sending HTTP requests, automating tests, or managing API collections. The best options in 2026 include Keploy, which auto-generates API tests and mocks from real traffic, along with Insomnia, Bruno, Hoppscotch, SoapUI, Thunder Client, and REST Assured for manual, exploratory, and code-first testing.…

Software Deployment in 2026: Strategies & Best Practices
Most software projects fail not in development – but at software deployment. Even stable, well-tested code can break in production when the deployment process isn’t planned well. In 2026, software deployment is no longer just about pushing code – it’s about reliability, speed, and control. Let’s explore how modern teams deploy smarter, faster, and safer…

Faster Testing: How Modern Teams Ship High-Quality Software Quickly
Software teams today are challenged to provide high quality releases at a much faster pace than ever before. As software development cycles become shorter, user expectations continue to increase and products become more complicated, testing becomes a bottleneck in the overall delivery process. Rather than reducing testing, the goal is to evolve testing to be…

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…
