Why Averages Lie: Mathematical Methods for Load Testing
Relying on “average” metrics alone makes load testing surprisingly inaccurate. In this article, we’ll show how to avoid the usual traps and walk through practical techniques for mathematically modelling a workload profile, from analyzing variance and correlations to spotting Simpson’s paradox and validating the final model. When a company moves to a new system, the […]
UI Load Testing: Full Guide
When an application starts to slow down, users notice it immediately. Pages hesitate to load, buttons lag, animations freeze for a split second, and that’s often enough to make someone close the tab. These issues rarely come from the backend alone. In most cases, the real strain appears in the browser, where scripts, styles, and […]
Internet of Things Testing: Benefits, Best Practices, & Tools for Reliable Connected Systems
IoT is an ecosystem of devices connected through networks and relying on cloud or app services for endless communication, data exchange, and smart automation. For this ecosystem to work seamlessly 24/7, it heavily depends on IoT testing. Apart from impeccable performance, the latter guarantees the reliability, protection, and integrity of diverse devices, networks, apps, and […]
Swagger API Testing: What It Is, How It Works, and Best Practices for QA Teams
Testing APIs without proper documentation can feel like walking through fog — every endpoint is a guess, every parameter a risk. But not with Swagger UI API testing. Swagger turns static API definitions into a live, interactive interface where developers and QA teams can validate endpoints, check request/response schemas, and explore the system in real […]

BlazeMeter vs. JMeter: Full Comparison
Ever wondered whether you should stick with Apache JMeter or move your tests to BlazeMeter? Both tools are powerhouses in performance and load testing, but they serve different needs. JMeter is an open-source desktop tool under the Apache 2.0 license; ideal for local or distributed testing across HTTP, APIs, JDBC, and more. BlazeMeter, on the […]
Endurance Testing: What It Is, Types & Examples
When performance engineers talk about endurance testing, they usually mean soak testing — a long-duration performance test that keeps the system under a steady, realistic workload for hours or even days. It’s designed to uncover what short stress or load tests can’t: slow memory leaks, growing queues, or throughput that quietly drops overnight. By tracking […]
Top 5 AI Load Testing Tools in 2025: Smarter Ways to Test Performance
AI is quickly becoming the most overused promise in software testing — every platform now claims it, but few can prove it.Some “AI load testing tools” genuinely analyze data, learn from patterns, and generate meaningful insights. Others stop at fancy dashboards and static scripts dressed in new terminology. In this comparison, we’ll separate real machine […]
What is Mock Testing?: Everything You Need To Know
Software teams often face a challenge when certain parts of a system aren’t ready, unstable, or too costly to call during testing. That’s what mock testing is for. By simulating dependencies, engineers can verify functionality without relying on real services. For many, understanding mock test meaning provides clarity: it’s about creating safe, controllable environments for […]
