}

src/solution.test.ts

import { solution } from './solution';

  expect(solution(1, 2)).toBe(3);
});

test('test2: adding negative numbers', () => {
  expect(solution(-1, -2)).toBe(-3);
});

test('test3: adding a string and a number', () => {
  // To handle this case, you might need to adjust the function or the test
  // For demonstration, assuming the function strictly accepts numbers
  // This test will fail and needs to be handled appropriately
  // Alternatively, you can use type assertions or overloads
});
