Breaking things fast: A new Approach to QA and testing

This post is based on Greg Qualls, Director of Product Marketing, presentation, "Accelerating QA and Testing," at SymfonyCon 2024. We utilized AI tools for transcription and to enhance the structure and clarity of the content. Before we dive in, I have over 18 years of experience in sales. If, at times, I sound like I'm trying to sell you something, please forgive me. I promise I'm not.

Streamline Code Testing with Proxymock

Tired of complex setups and running out of memory just to test one component? Learn how to use Proxymock (a FREE tool) to solve your biggest testing headache: component isolation! This demo shows you how to record and mock interactions across a complex React, Golang, and PostgreSQL stack, allowing you to find bugs before they ever hit production. In This Demo: This strategy lets you easily isolate components, simulate customer behavior, and ensure quality with lightning-fast local testing.

Capture and Use Network Response Data in AI Powered Testing

Learn how to capture and use response data from network calls to build smarter and more reliable AI-driven tests. This walkthrough covers the full workflow from configuring user actions to extracting backend responses, validating data, and creating dynamic test flows. You will also see how response data improves debugging visibility and supports data-driven automation. The video includes Ideal for developers, testers, and platform engineers looking to improve the accuracy and resilience of AI-powered test suites.

Get 97% faster feedback with Smarter Testing by CircleCI

Fast feedback is the foundation of software delivery at scale. Long build and test cycles break developer focus, turning simple changes into momentum-killing pauses. Studies show that recovering from these interruptions can take twenty minutes or longer. Multiply that by dozens of commits per day and context‑switching time quickly turns into days of lost productivity.

End-to-End Testing for Microservices: A 2025 Guide

End-to-end testing has always been a double-edged sword - even more so in the world of microservices. On one hand, E2E tests are critical for validating that all services work together seamlessly in real user flows. On the other hand, many experts warn that heavy reliance on end-to-end testing in a microservices architecture can create a "distributed monolith," slowing down deployments and undermining the very agility microservices promise. There's truth to that: if done poorly, E2E tests can become brittle, flaky, and a bottleneck that reduces your deployment frequency.

Usability Testing Explained: How to Evaluate User Experience and Improve Product Design with Harness

Usability testing is a powerful method for understanding how real users interact with your product, and uncovering the friction, confusion, and hidden roadblocks that can impact the user experience. In this video, we break down what usability testing is, why it matters, and how observing real user behaviour can help teams create more intuitive, user-friendly software.

What Is a T-Test? A/B Testing with Statistical Confidence

When running A/B tests, how do you know if the results are actually meaningful — or just random chance? That’s where the t-test comes in. In this video, we explain how t-tests help you evaluate whether changes in conversion rates, engagement, or performance metrics are statistically significant. You’ll learn how they work, when to use them, and why they’re essential for making confident product, marketing, and engineering decisions.

What Is Multivariate Testing? A Guide to Experimenting With Multiple Elements

A/B testing is great — but what if you want to optimize more than one thing at a time? That’s where multivariate testing (MVT) comes in. In this video, we break down how MVT works, why it gives you deeper insights than A/B testing, and how you can use it to test multiple page or app elements at once. You’ll learn how to run multivariate tests, when to use them over A/B tests, and how Harness makes this seamless inside your CI/CD pipeline.
