How Pact Contract Testing Catches Breaking Changes That WireMock Misses
The Contract That Survives the Agent A Level 5 Engineer — Issue #4 Preface I want to be upfront about something before we get into it. None of the frameworks in this article is mine. The ideas here come from two people who have been thinking about this stuff way harder and longer than I have — ...
Testing in Rust: from cargo test to mocking HTTP calls
People love to repeat that in Rust "if it compiles, it works". The compiler does kill a whole class of bugs, but it doesn't check your logic. A wrong discount calculation compiles just fine.
How to Compare Testing Tools Without Getting Fooled by Feature Checklists
The biggest mistake teams make when comparing testing tools is treating the feature list like the decision. A tool can support API tests, visual checks, CI, reporting, and integrations, and still be the wrong choice if nobody adopts it, the runs are flaky, or the billing model turns into a budge...
DevOps Pipeline: Stages, Tools, and CI/CD Explained
Most teams don't fail at writing code. They fail at getting it to production reliably, quickly, and without someone staying late to babysit a deployment script. A well-constructed DevOps pipeline is the answer to that specific problem — and once you've set one up properly, you'll wonder how you...
Working Code, Wrong Engineering: Why AI-Generated Code Needs System-Definition Tests
AI-generated code can work perfectly and still fail as engineering. It passes all functional tests while introducing SaaS cost drift, operational burden, license incompatibility, lifecycle drift, internal-platform drift, optimization drift, and failure-behavior drift. Functional tests are no lo...

The biggest risks lurking inside your at-home DNA and health tests
What's really in that DNA kit? Hint: It's not just a spit tube, but a whole lot of fine print.
OpenAI Tests Investor Appetite for Yet Another Giant I.P.O.
Some analysts are wondering whether the market can absorb the artificial intelligence giant’s planned stock offering — along with those of SpaceX and Anthropic.
Show HN: We post-trained a model that pen tests instead of refusing your code
I'm Dimitrios at Cosine. Quick orientation first: the read-only scan is free and you can run it right now: that's the part to try. The pen-test mode is gated behind written authorisation, because it's live offensive testing against real systems; I'll explain that below, it's not a paywall thing.
