testCasesWithinDescribes

Reports importing from node:test.

✅ This rule is included in the vitest stylisticStrict presets.

Vitest allows declaring standalone hooks and tests: those not in a parent describe() block. Some repositories prefer to always include those in a describe() for consistent test case grouping.

This rule reports on any hook or test declaration not in a parent describe() block.

Examples

❌ Incorrect

beforeEach(() => {
  // ...
});

test("...", () => {
  // ...
});

✅ Correct

describe("...", () => {
  beforeEach(() => {
    // ...
  });

  test("...", () => {
    // ...
  });
});

Options

This rule is not configurable.

When Not To Use It

If you don’t want to have all hooks and tests declared in describe() blocks, this rule might not be for you. For example, smaller and/or tightly-organized repositories often have one test file per component or function under test, and so are organized into groups that way already.
