    },
  },
]);

#Rule Details

Disallow Jest lifecycle hooks (beforeEach, afterEach, beforeAll, afterAll). This rule helps enforce tests that are isolated and explicit, instead of relying on shared setup/teardown behavior that can make test order and failures harder to reason about.

Examples of incorrect code for this rule:

beforeEach(() => {
  setupDatabase();
});

afterAll(() => {
  cleanup();
});

Examples of correct code for this rule:

test("works with explicit setup", () => {
  const db = createTestDatabase();
  expect(runWith(db)).toBe(true);
});

describe("suite", () => {
  test("case", () => {
    expect(1 + 1).toBe(2);
  });
});

#Options

• First argument (optional): object with allow
  • allow: array of hook names that are allowed. Supported values: beforeEach, afterEach, beforeAll, afterAll.
