When I run my tests I get the following example error:

error: Relative import path "@services/chain/types/chain_types.ts" not prefixed with / or ./ or ../
    at file:///workspaces/maicro/backend/test/1000.config.and.files/1000.config.test.ts:6:26

But my app runs, and deno check doesn't complain about any issues.

imports from my deno.json

  "imports": {
    "zod": "npm:zod@^3.24.1",
    "appwrite/": "npm:appwrite@^16.0.2/",
    "@services/": "./services/",
    "@common/": "./services/common/",
    "@test_tools/": "./test/test_tools/"
  }

Screen snip attached showing when I am editing in code, no errors are indicated.

The issues only start when I try to run tests that contain aliases.

Any thoughts

Deno Aliases causing errors in tests.

I've done a bit more basic checking, using aliases in main.ts successfully. But when used in any test, that test fails with the error shown in the previous screen snip.

Can you file an issue for that https://github.com/denoland/deno/issues ?
