Question

Accepted Answer

**Gwaje-gwaje da aka tsara ta hanya (gwaje-gwaje da aka miƙa bayyanai)** suna gudna **logic din gwaje guda da kuma saitanni da yawa na shigarwa da jiga-jigaw na sakamako** — ba tare da kwatantawa na gwaje don kowane harka ba. Suna sauƙi aiki don gwaje saitanni masu yawa (gami da haranganci na gida) cikin karɗa mai karfi.

## Matsala: gwaje-gwaje da aka kwatanta

```text
Without parameterization, testing many input/output cases means COPYING the test:
  test('add 2+3', () => expect(add(2,3)).toBe(5));
  test('add 0+0', () => expect(add(0,0)).toBe(0));
  test('add -1+1', () => expect(add(-1,1)).toBe(0));
  → lots of near-identical, repetitive tests (tedious, hard to maintain)
```

## Gwaje-gwaje da aka tsara ta hanya — gwaje guda, saitanni da yawa

```js
// run the SAME test logic over a TABLE of cases (Jest's test.each)
test.each([
  [2, 3, 5],
  [0, 0, 0],
  [-1, 1, 0],
  [100, 200, 300],
])('add(%i, %i) === %i', (a, b, expected) => {
  expect(add(a, b)).toBe(expected);     // one logic, run per case
});
// → each row is a separate reported test case; add a case = add a row
```

```text
✓ CONCISE — test many scenarios without duplicating the test body
✓ Easy to ADD CASES — just add a row of data (great for edge cases / many inputs)
✓ Each case reported SEPARATELY — you see exactly which input failed
✓ Clear, maintainable — the data table documents the cases
→ Ideal for functions with many input/output combinations and edge cases.
