How to Do Load Testing With CloudQA

Last updated: October 2026

Quick answer

CloudQA load testing is a service we run on request. You tell us what you are preparing for, such as a launch, a sale or a big release, and which user journeys matter. We reuse your recorded CloudQA tests (or record them with you), combine them into a realistic scenario mix, and run many real browser sessions at once while ramping up traffic. You get a report showing where response and render times start to slip, which steps fail under load, and where your breaking point is.

What is load testing?

Every application has a limit: a number of simultaneous users or requests beyond which pages slow down, errors appear or the system fails. Load testing finds that limit in a controlled test, before real customers find it during a launch, a marketing campaign or a seasonal peak. Sites from government portals to retailers on Black Friday have learned this the hard way.

Why teams skip load testing, and why they should not

• “We do not have many users yet.” Launches and campaigns create sudden spikes; the first big day is exactly when you need to be ready.
• “We lack the skills or tools.” Protocol-level scripting is specialized work. Running real-browser scenarios from journeys you already have removes much of that barrier.
• “Our functional tests pass.” Functional tests run one user at a time. They say nothing about behavior with hundreds or thousands at once.
• “The cloud will scale.” Auto-scaling helps, but databases, third-party services, caches and rate limits often become bottlenecks first.

How a CloudQA load test works

1. Tell us what is coming. Share your goals, expected traffic and the journeys that matter most, such as browse, search and checkout.
2. We prepare the scenarios. We reuse your CloudQA regression tests or record the journeys with you, then agree the scenario mix, think time and test data.
3. We run the test. Many real browsers run the scenarios at once on cloud test nodes, ramping load up over a short period, optionally from several locations.
4. You get the results. Response and render times for every step as load increases, errors and failed steps, and the point where performance breaks, walked through with our team.

Real-browser vs protocol-level load testing

Both have a place. CloudQA can also export workflow scripts to JMeter when you need protocol-level volume.

When to load test

• Before launches, marketing campaigns and seasonal peaks.
• After major architecture, infrastructure or hosting changes.
• When adding significant new third-party integrations.
• Periodically, to confirm performance has not drifted.
