Browser-side chaos testing with a Service Worker

/u/OtherwisePush6424 Reddit r/webdev 2026-09-07 21:25 3 views

A browser-side chaos-testing tool that installs a Service Worker to intercept requests across every controlled tab and apply latency, failures, throttling, rate limits, and mock responses without changing app fetch calls (similar to MSW).

It uses the same middleware configuration model as chaos-fetch, so you can test real frontend behavior under degraded network conditions without rewriting the app to use a special client wrapper.

Unit Testing in C# with xUnit and Moq: Proving the Repository Pattern Actually Pays Off

The Repository Pattern post said, more than once, that BookReservationService was "genuinely unit-testable with a mock," because it depends on IBookRepository, an abstraction, rather than a concrete class talking directly to a real database. That claim was never actually backed up with a real test.

Technical considerations in the design of the Obra shadcn/ui kit Thursday this week, Figma released the opacity within variables feature, which allows authors to use an opacity percentage while keeping a color bound to a variable. We have been looking how to implement this correctly in our kit. A

[$] Fixing the TCMalloc regression with RSEQ operations

The restartable sequences feature is one of the stranger corners of the kernel's user-space interface; it provides a way for user space to carry out simple lockless operations and be informed if it is preempted over the course of an operation (and must, thus, restart). Work merged in the 6.19 relea
