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 […]

Custom Load Testing for Speech Recognition and TTS: Lessons from SpeechKit
SpeechKit Architecture and Use Cases SpeechKit services are more than just an API that takes a request and sends back a response. Alongside the core speech-to-text (STT) and text-to-speech (TTS) models, the platform usually includes supporting layers such as text normalization, punctuation restoration, and authentication. In some deployments, it may also integrate additional modules: for […]
JMeter API Testing: Step-by-Step Guide
APIs drive today’s applications, connecting services and delivering the responses users expect instantly. To make sure they run smoothly under real-world conditions, teams turn to performance testing. JMeter API testing is a proven approach that allows QA engineers to simulate traffic, measure response times, and identify bottlenecks early. This guide explains the essentials of API […]
Key Performance Test Metrics You Need To Know
Keeping applications stable under load depends on tracking the right performance testing metrics. These measurable values highlight how a system behaves when real users, heavy requests, or third-party integrations come into play. Engineers use performance test metrics to understand system health, guide optimization, and validate business expectations. This guide explores commonly used load testing metrics, […]
Synthetic Test Data: Detailed Overview
Testing software without the right data is like rehearsing a play with no script; you can’t see the full picture, and mistakes slip by unnoticed. Synthetic test data offers a practical way to solve this problem. In this article, we’ll explore what it means, how it’s generated, and the situations where it proves most valuable. […]
