JMeter Parameterization: Full Guide from PFLB
The importance of JMeter parameterization in modern IT is undeniable for both technical and business stakeholders. This data-driven testing approach allows QA engineers to execute real-world performance tests quickly, efficiently, and with minimal errors, and lets businesses reduce the risk of severe operational bottlenecks and costly downtime. In this comprehensive guide, we look at parameterization […]
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. […]
5 Load Testing Tasks Engineers Should Automate with AI Right Now
Load testing is essential, but much of the process is repetitive. Engineers spend hours correlating scripts, preparing datasets, scanning endless graphs, and turning raw metrics into slide decks. None of this defines real expertise — yet it takes time away from analyzing bottlenecks and making decisions. Modern platforms are embedding AI where it makes sense: […]
7 Best Continuous Testing Tools to Start Using Today
Identifying and fixing software flaws early in SDLC is much more effective than doing so after release. With the right continuous testing solutions, IT professionals can easily detect and resolve software issues before they escalate into greater problems and businesses can ensure faster time to market and eliminate potential re-engineering costs. In this guide, we’ll […]
Best API Load Testing Tools for 2025
APIs are the backbone of modern applications, and their stability under load directly impacts user experience. Without proper testing, high traffic can cause slowdowns, errors, or outages. API load testing tools help simulate real-world usage by sending concurrent requests, tracking response times, and exposing bottlenecks. In this guide, we’ll review the top API load testing […]
