Kwalay kake amfani da AI mai taimakon rubuta baje masu gwaji ga aikin da ake da shi?

Question

Accepted Answer

Idan aka yi aiki daidai, AI ba a sama da ita a game da **ƙidayar" bahagi na baje — tana tsara halin ƙanƙanta kuma tana rubuta boilerplate da sauri. Amma kuna yakamata **tabbatar da cewa takaitawa ba a bada ma'ana" ba", saboda AI zai rubuta da gamji baje wajen da ba su katantawa ba.

## Jarin aiki

1. **Ba shi aikin da yarjejeniyarsa" — abin da ya kamata ya yi, nau'ikan aiki/ƙarfi, da yadda ya kamata ya dauke baje mai rashin ƙarfi. Baje ba za su iya zama muni da ƙayyadaddun ka nuna ba.
2. **Ka tambayi a bayyane ga halin ƙanƙanta" — iyakatai (0, wofi, mafi girma), da hanyoyin kuskure (null, marasa kyau, nau'i mara kyau), ba kawai hanya mababbaki ba.
3. **Tabbatar da cewa takaitawa ba a bada ma'ana ba" — baje da ke takaitin halaye na yanzu ta code (ko da yake bugi ne) ba a bubugi ne. Bari kowane takaitawa kodaya da aka yi na *da ikonku" yarjejeniya.

## Misali

```js
// Function under test, with its contract:
// applyDiscount(price, percent) -> price reduced by percent.
// Contract: percent must be 0..100; throws RangeError otherwise. price >= 0.
function applyDiscount(price, percent) {
  if (percent < 0 || percent > 100) throw new RangeError('percent out of range');
  return price - (price * percent) / 100;
}
```

```js
// AI-suggested test cases (Jest) — note the edge and error paths, not just happy path:
test('applies a normal discount', () => {
  expect(applyDiscount(100, 20)).toBe(80);       // happy path
});
test('0% leaves price unchanged', () => {
  expect(applyDiscount(100, 0)).toBe(100);       // boundary: lower edge
});
test('100% makes it free', () => {
  expect(applyDiscount(100, 100)).toBe(0);       // boundary: upper edge
});
test('rejects percent above 100', () => {
  expect(() => applyDiscount(100, 150)).toThrow(RangeError); // error path
});
```

AI ta shawara halin ƙanƙanta (0 da 100) da hanyar kuskure da kila ga kulae. Aikinku shine tabbatar da *daidai* jigon da aka sa ran shi ne, ba kawai abin da aikin ya dani ba.

## Me ya sa hakan ya matukar mahimmanci

Wani mahadi na baje ba ya yin rubutu `test(...)` tugale ba — shine *tunani game da halin wajen da ba ku ajiya ba", kuma AI ba ta da hakika a gogayen gajiye. Amma ba ta da wani sani abin da code dinku ya kamata ya yi sai kun gaya maa, saboda haka ba tare da kulawa ba tana yin *baje wajen da suke aika* (suna wucewa, amma za su wuce ko da yake aikin ya yi kuskure). Wayar AI daidai azaman jigon halin ƙanƙanta janareta yayin da kuke masanyan takaitawa yana ba ku faɗakar koli da gaske daidai — sauri daga AI, hankali daga gida.
