    max-expects

    Added in v0.8.2

    Configuration

    rslint.config.ts
    import { defineConfig, rstestPlugin } from '@rslint/core';

export default defineConfig([
  rstestPlugin.configs.recommended,
  {
    rules: {
      'rstest/max-expects': 'error',
    },
  },
]);

    Rule Details

    Limits completed assertion chains in each Rstest test or hook callback. A smaller test is usually easier to understand because it verifies one behavior at a time.

    Each expect(...), expect.soft(...), expect.poll(...), or expect.element(...) assertion counts once. Static helpers such as expect.any() do not count.

    Incorrect

    test('returns an active user', () => {
  expect(user.id).toBe(1);
  expect(user.name).toBe('Ada');
  expect(user.active).toBe(true);
  expect(user.role).toBe('admin');
  expect(user.email).toBe('ada@example.com');
  expect(user.createdAt).toBeInstanceOf(Date);
});

    Correct

    test('returns the user identity', () => {
  expect(user).toMatchObject({ id: 1, name: 'Ada' });
});

test('returns an active user', () => {
  expect(user.active).toBe(true);
});
