vitest/consistent-vitest-vi

Vitest exports its helper object under two names, vi and vitest. They're the same object. Using one name means a search for vi.mock finds every mock in the project.

By default the name is vi. Both the import and the calls are reported.

--fix renames the import and the calls.

Configure

Off by default. To turn it on:

[lint.rules]
"vitest/consistent-vitest-vi" = "error" # or "warn"

Every option, set to its default:

[lint.rules]
"vitest/consistent-vitest-vi" = ["error", {
  fn = "vi",
}]

Examples

Reported:

import { expect, test, vitest } from "vitest";

test("calls the listener", () => {
  const listener = vitest.fn();
  emit("save", listener);
  expect(listener).toHaveBeenCalled();
});

Not reported:

import { expect, test, vi } from "vitest";

test("calls the listener", () => {
  const listener = vi.fn();
  emit("save", listener);
  expect(listener).toHaveBeenCalled();
});

Options

Option	Default	What it does
fn	"vi"	The name to use: "vi" or "vitest".

With "vitest", vi is reported:

import { vi } from "vitest";

vi.useFakeTimers();
