Kawayen ku teste aikace-aikacen React Native?

Question

Accepted Answer

React Native yana goyan bayan gwaji a matakai da yawa — **gwajin raka'a** (dabarbari), **gwajin sassa** (tare da React Native Testing Library), da **gwajin daga gida zuwa gida** (tare da Detox). Dabarun gwaji mai kyau yana haifar da kuɗi da aminci.

## Gwajin raka'a da sassa (Jest + Testing Library)

```text
JEST → the standard JS test runner (unit tests for logic, functions, hooks)
REACT NATIVE TESTING LIBRARY → test components by rendering and interacting with them
  (the way a user would) — query elements, fire events, assert on output
```

```jsx
import { render, fireEvent, screen } from '@testing-library/react-native';

test('increments counter', () => {
  render(<Counter />);
  fireEvent.press(screen.getByText('Increment'));   // interact
  expect(screen.getByText('Count: 1')).toBeTruthy(); // assert
});
```

React Native Testing Library yana gwada sassun tsakanin makyatance (juyawa, aiki, tabbatarwa) — yana ƙoƙarin gwajin da suke kama da ainihin amfani.

## Gwajin daga gida zuwa gida (Detox)

```text
DETOX → E2E testing on a real device/emulator — tests full user flows (launch the app,
  tap through screens, verify behavior) like a real user, across the whole app
  → slower but tests the integrated app end-to-end (Maestro is another popular E2E tool)
```

## Dabarun gwaji

```text
→ Test PYRAMID: many unit tests (logic), component tests (UI behavior), fewer E2E (flows)
→ Test important logic, component behavior, and critical user flows
→ Mock APIs/native modules; test on both platforms for E2E
→ Testable architecture (separate logic from UI) makes testing easier
```

## Me ya sa haka makumbaci

Sanin yadda ake gwada aikace-aikacen React Native yana da muhimmanci a matakin sanin mahimman abubuwa saboda **gwaji yana haifar da kuɗi da aminci**, yana ba da damar canjin abubuwa ba tare da karya abubuwa ba, don haka yana da amfani a gwagwarwakin kasua.

React Native yana goyan bayan dabarun gwaji a matakai da yawa, da sanin kowannan yana mahimmanci. **Gwajin raka'a** (tare da **Jest**, jiya mai santsi don gwaji, don dabarbari, ayyuka, da hooks) yana tabbatar da dabarbarin aikace-aikace — tushe. **Gwajin sassa** (tare da **React Native Testing Library**, juyawa sassun tsakanin abinda mai amfani zai yi — neman abubuwa, fitar bugun jari, tabbatarwa a aikin bajaɗo) yana da mahimmanci musamman saboda yana gwada sassun tsakanin makyatance da almakamantarwa tare da maimakon ka, yana ƙoƙarin gwajin da suke kama da ainihin amfani da suka kama da kyau ga matsalar halayyar UI, aiki na mahimmanci don gwada React Native UIs. **Gwajin daga gida zuwa gida** (tare da **Detox** ko Maestro, gwada cikakken jerin abubuwa na mai amfani akan ainihin na'ura/emulator kamar mai amfani na gaske) yana kama da matsaloli cikin aikace-aikace, ko da yake sannu.

Sanin dukan matakai uku da lokaci dona kowannan yana bukatarwa ga gida gida na gwaji.

Sanin **dabarun gwaji** — pyramid na gwaji (raka'o'i da yawa, sassun gwaji don halayyar UI, gwajin E2E kaɗan don jerin abubuwa), gwada mahimman dabarbari da cikakken jerin abubuwa, yin amfani da maɓugoji da modules na gida, gwada akan duka jeri don E2E, da cewa **gida makumbaci** (raba dabarbari daga UI) yana sawa da gwaji - yana nuna ingantaccen, ma'auni abinda ya wada abinda ya wada.

Gwaji yana haifar da kuɗi (kama da ƙupu), yana ba da damar aminci canjin (sanin cewa gwaji yana kama da buyewa), da yana alamar sanataccen devaloppement.

Do waje da gwaji yana mahimmanci don gina jeri da maye likita, da React Native yana ba da kayan gwaji a matakai uku na raka'a (Jest), sassa (Testing Library), da E2E (Detox), da do waje da sanin matakai da dabarun aiki makumbaci yana muhimmanci don sanataccen devaloppement, sanin yadda ake gwada aikace-aikacen React Native yana muhimmanci, tunani mai amfani - mahimmanci don gina jeri tare da aminci, nuna aiki-da-gida, da amfani musamman tare da React Native Testing Library's makyatance-makyatance sassa gwaji, aiki na mahimmanci don kuɗi na React Native devaloppement.
