Skipping time in tests; time delay setTimeout setInterval

(the title is just so people can get to this one easier by using search) I have a deadline/delay based (@std/async) functionality and in tests I want to skip time (so I don't have to pass lower values for timeouts). I want something like jest's advanceTimersByTime (very bright page warning, usage is at the bottom) https://jestjs.io/docs/timer-mocks (jest uses sinon's fake timers, sinon uses sinon/fake-timers (install, then createClock, it's basically a big orchiestrated mock on time-based apis)) No idea if sinon works with deno (and if it is the deno's way), I would prefer something jsr/deno for this, any recommendation?

Deno.test with "each" support

I tried to find in docs if something like https://deno.land/x/test_each@v0.0.2 or jest's https://jestjs.io/docs/api#each exists in Deno.test Looks like it is not, if you know that I missed something or there's a common pattern of doing this in Deno.test (like idk... mapping an array into an array of asserts and somehow getting the correct message out - please steer me into the correct direction.

Recommended `denoland/deno` contributor editor setup

I have a problem with deno trying to redefine itself via random declare namespace Deno { ... } throughout the deno repo. I use vscodium with TypeScript 5.2.2, latest Deno. I fail to find any docs on how you recommend to setup the editor to make lsp correctly pick up things.

Deno+vite crashes on node dependency

Earlier today I was happy because everything worked on my m1 macbook. When I've returned home (arch) I got errors from latest deno... (I am running deno on the metal, but I will provide a way to reproduce it with docker:)

Read-only FS detection

Hi, I have few deps that by default create cache/log dirs... I can disable it, but the detection itself is unclear. Is there a better way than

const canWriteToFs = (() => {
  try {
    Deno.mkdirSync("./log", { recursive: true });
    return true;
  }
  catch {
    return false;
  }
})();

const canWriteToFs = (() => {
  try {
    Deno.mkdirSync("./log", { recursive: true });
    return true;
  }
  catch {
    return false;
  }
})();

Peer dependency

Can I somehow mark a dependency as "peer"? So this dependency (which is known to shuffle typings between versions, but generally it is nonbreaking if you use it on highlevel) will not enforce a specific version onto a project? I depend on Pentagon and Zod Pentagon also depends on Zod While I initially wanted to use different version of Zod than pentagon's (using different versions of Zod makes some inner types clash) (I can switch zod version to pentagon's, but I feel not everybody would have the same luxury in the future) If possible - I would like to avoid this solution: https://github.com/denoland/deno/issues/10356#issuecomment-1580352563
