Device farms reuse hardware to cut costs, but that breaks test stability. QA Wolf built a new system: real devices, clean state, no flakes. Learn how we deliver fast, reliable mobile test automation across Android and iOS.

The Playwright vs. Cypress debate is sure to go on, but when it comes to testing complex workflows, Playwright is better than Cypress for QA Wolf and our customers.

Most AI testing vendors frame “self-healing” as fixing broken selectors. But selectors cause only a minority of failures. See how our AI applies a diagnosis-first approach across six failure categories.

Codeless AI systems promise speed but remove the determinism and interpretability that make results trustworthy. This post shows how that breaks the experiment—and how code restores it.

Automated testing makes QA faster, but brittleness slows teams with constant rework. AI agents don’t stop tests from breaking—they handle the maintenance, adapting in real time so stability, reliability, and adaptability can reinforce each other.

AI IDEs like Copilot and Cursor generate test code quickly, but they only cover a fraction of QA. Real QA requires planning, investigation, and reporting—the areas that drive release confidence.

Every environment is different — that’s the point — so your end-to-end tests should run in the environments as checkpoints that answer specific contextual questions.

The Test Pyramid was built for a time when infrastructure was slow and parallelism was hard. E2E tests weren’t the problem—execution environments were. That’s no longer true. With the right infra, E2E tests can be fast, stable, and worth the cost.

Full parallel testing is hard. But in the long run, other approaches to test execution cost more in productivity and dollars. Learn how you can help your team deliver a quality product faster and save money.

PR testing sounds fast, but often delays releases with flaky tests, infra strain, and unclear failures. RC testing validates a stable build before release—cutting noise, reducing rework, and aligning QA and dev around quality that scales.

Master the fundamentals of end-to-end testing so your team can catch bugs early, scale confidently, and ship with speed.

Test automation is easy to start—but hard to sustain. This post breaks down seven common reasons teams stall out after launch, from flaky tests to infrastructure bottlenecks, and how to move from proof-of-concept to real coverage.

PR testing promises speed and confidence—but often delivers flakes, bottlenecks, and burnout. Learn why it goes sideways and what to fix before you make the switch.

You’re not imagining things. Everything that makes E2E regression testing difficult is infinitely more challenging when you’ve integrated with or built on top of Salesforce. 

Mobile tests flake when device, app, or data state isn’t reset. QA Wolf controls all three, so tests start clean and run the same way every time.

The thing about pricing models is that they always seem to make sense, until someone comes around and does something different. In every case, the old pricing model prioritized the vendor’s costs over the buyer’s needs. Which is what’s been happening with QA since the very first QA vendor appeared.

Android emulators are essential for scaling mobile test automation—but instability can derail even the best test suites. This guide covers five proven strategies to reduce crashes, improve performance, and make your end-to-end tests more reliable.

After thousands and thousands of end-to-end tests, we've picked up a few tricks to build fast, stable, and accurate ones. So come along and we'll teach you how to build automated tests the QA Wolf way.

When QA teams own end-to-end testing without the right systems, test maintenance takes over and coverage stalls. Give them the tools to do what they do best: catch meaningful bugs before they reach production.

When it comes to automated end-to-end test suites, the total cost of ownership(TCO) is driven by the amount of testing your team does, the number of tests in a test suite, and how frequently you run them.

Attention, gear heads: Learn the details of our Kubernetes implementation that enables us to execute fully parallelized test runs, whether there are 200 tests in the run or 20,000.

Outsourcing the creation of your automated end-to-end tests and then handing them to your in-house team might seem like a good idea. Here's why your expectations likely don't match reality.

Crowdsourcing has some valid use cases. But before you decide to go with a crowdsourcing vendor for automated testing, make sure you understand the drawbacks. This blog will tell you when it's is the right testing strategy for your project and when you are better off with something else.

We've come a long way since the Browser Wars and automated cross-browser testing is probably not worth the expense, except in a handful of cases.

Counting tests isn’t the same as understanding your test coverage. These six metrics track signal quality, flake rates, skip rates, and workflow alignment to show whether your coverage helps you catch bugs early—or just slows your team down.

Shifting left doesn’t mean developers should own E2E testing. When they do, test quality drops, coverage gaps grow, and delivery slows. Let devs focus on building—leave black-box testing to QA.
