Mastering waits and timeouts in Playwright

Jan 21, 2026 By Waweru Mwaura In CircleCI

If you have written any kind of end-to-end tests or UI tests you probably know that the greatest headache to deal with is test flakiness due to browser actions not behaving in the way that you expect them to behave. This flakiness can be a major bottleneck especially in CI/CD pipelines due to constant failures.

ROI of Digital Twin Testing: Cut Testing Costs by 50%

Jan 20, 2026 By Ken Ahrens In Speedscale

When engineering leaders review their cloud bills, they often focus on production costs—the infrastructure serving real users, processing real transactions, generating real revenue. But there’s a shadow cost lurking in every cloud environment that often goes unnoticed until it becomes painful: non-production infrastructure.

Digital Twins Gone Wild: My Unexpected AI Doppelgänger

Jan 20, 2026 By Alan Mon In Speedscale

I recently tried using AI to create a digital twin of myself. I uploaded a photo, expecting a futuristic, slightly improved version of me... and what did I get in return? A picture of Kim Jong Un. Clearly, AI has a sense of humor-or a very different definition of "twin." Forget Arnold Schwarzenegger and Danny DeVito. Digital Twins 2-Now Starring My AI Doppelgänger From Speedscale's perspective, a digital twin is built from real production traffic, continuously updated, and executable in your test and CI/CD environments.

Mock vs Stub: Essential Differences

Jan 16, 2026 By Nate Lee In Speedscale

When discussing the process of testing an API, one of the most common sets of terms you might encounter are “mocks” and “stubs.” These terms are quite ubiquitous, but understanding exactly how they differ from one another - and when each is the correct method for software testing - is critical to building an appropriate test and validation framework. In this blog, we’re going to talk about the differences and similarities between mocks and stubs.

How to Keep Clinic Software Running 24/7: Preventing Overnight Downtime

Jan 14, 2026 By OpsMatters In OpsMatters

Operating a medical practice is already hectic enough without the fear of whether your clinic software is going to be running the next day when you get in the door. However, the truth is as follows: 24-hour downtimes not only are irritating, but also may disrupt the care of patients, schedule appointments, and make the work of those who have to use that system operational at 7 AM a nightmare.

Automate flaky test fixes with the Bits AI Dev Agent and Test Optimization

Jan 12, 2026 By Eric Metaj In Datadog

Flaky tests are a significant source of inefficiency that impacts many engineering teams. Along with failing your build, they interrupt your entire development flow, generate excessive CI/CD noise, and, critically, compromise developer trust in the test suite itself. Datadog Test Optimization enables you to manage test suites at scale by pinpointing the flakiest tests, analyzing their history across hundreds of runs, and automatically surfacing the root cause.

Speedscale vs. LocalStack for Realistic Mocks

Jan 9, 2026 By Damaso Sanoja In Speedscale

API mocking plays a crucial role in modern software development allowing developers to simulate external API endpoints. It’s an effective way to isolate your application for testing and ensure that code changes don’t inadvertently break critical dependencies. Essentially, API mocking helps you create robust, reliable software by allowing you to test how your application interacts with external services.

DLP: The Key to Secure K8s Testing #speedscale #dlp #kubernetes #devops #testing

Jan 7, 2026 By Speedscale In Speedscale

Testing with production traffic doesn't have to be a security risk. Engineers often avoid production data because of sensitive info like passwords, tokens, and PII. But legacy test data management is too static for modern, fast-changing payloads. Enter the Speedscale Streaming DLP Engine. It automatically detects and redacts sensitive data in real time as it's captured from your environment. You get the realism of production traffic without the risk of a data breach.
