Use `@effect/vitest` for tests in this repo.
## Fix Shape
- Import `describe`, `it`, `expect`, and helpers from `@effect/vitest`.
- Import utility helpers from `@effect/vitest/utils` when needed.
- Do not import from raw `vitest` except in config or tooling files.
- Do not put `expect(...)` behind `if`, ternary, logical, or switch branches.
- Split conditional behavior into separate tests, or assert the branch condition and expected value explicitly.
## Bad
```ts
if (result.ok) {
expect(result.value).toBe("x");
}
```
## Good
```ts
expect(result).toEqual({ ok: true, value: "x" });
```
