Cypress ships one toolchain to compile Angular component tests: webpack. Vite offers four more. I ran the same 41 tests through all five on Angular 22, in JIT and AOT where they support both, and compared speed, memory, and whether the tests still pass.
Twenty months after the first article, a look at where Rspack in Angular stands today, what the Nx team shipped, what Angular changed on its side, and whether it is worth the switch.
Three ways to turn an Nx test project into tasks: one per project, one per spec file (atomization), or balanced groups of specs (sharding). Every task pays a startup, and idle parallelism decides whether that's worth it.
