vitest/prefer-import-in-mock Style

🛠️ An auto-fix is available for this rule.

What it does

This rule enforces using a dynamic import() in vi.mock(), which improves type information and IntelliSense for the mocked module.

Why is this bad?

A lack of type information and IntelliSense increase the risk of mismatches between the real module and it's mock.

Examples

Examples of incorrect code for this rule:

js
vi.mock("./path/to/module");

Examples of correct code for this rule:

js
vi.mock(import("./path/to/module"));
