Outline
Here's a possible solution for testing the subtract.ts
file:
import { assertEquals } from 'https://deno.land/std/testing/asserts.ts';
import { subtract } from './subtract.ts';
Deno.test('subtract 2 and 2 = 0', () => {
const result = subtract(2, 2);
assertEquals(result, 0);
});
Deno.test({
name: '4 - 2 = 2',
fn: () => {
const result = subtract(4, 2);
assertEquals(result, 2);
}
});
