Well, first off, there are *at least three* commonly used things today that in some way intentionally violate no-floating-promises by design: Fastify, node:test, and RTK. So, clearly, at least some influential parts of the community disagrees with this. 😏

Trying to build a cross-runtime test suite that works on Node.js, Bun, and Deno, but hitting a roadblock with Bun's incomplete `node:test` implementation. Missing subtests/test steps support is making this harder than it should be.

Bun에서 `node:test` 모듈을 쓸 수 있긴 한데, 모든 기능을 다 제공하는 건 아니라서 이것에 의존하기가 어렵다. (적어도 내가 돌리려는 테스트는.)

hmmm might get everything moved over from Bun to Node.js because it seems weird having a mixed Bun/Node.js monorepo
chai + node:test seems ok enough, and i could use the --experimental-transform-types to get Node.js to transform enums/const enums

Mocking in node:test feels super smooth.
I've been doing mocks for testing for 15+ years and this is the easiest it has ever felt.

Spending some time today sprucing up a library by replacing mocha/chai/sinon with the built in node:test and node:assert.
I like having less dependencies! Still working through muscle memory of new apis though.

A good reason to use node:test is that you can focus on upgrading your runtime, instead of upgrading dependencies.
