React Native Mock - Javascript

React Native Mock is a powerful tool for quickly creating mock data in your React Native applications. It helps to simulate responses from APIs and servers, and can be used to test your app's functionality even if you don't have access to the real data.

Installation

To get started with React Native Mock, you'll need to install it as a dependency in your project. You can do this easily using npm:

npm install react-native-mock --save-dev

Usage

Once you've installed React Native Mock, you can begin using it in your project. The library includes a number of functions for creating mock data, including mock, mockData, getMockFunction, and getMockPromise.

Creating a Mock

To create a mock with React Native Mock, you can use the mock function. This function takes an object that defines the shape of the data you want to create.

import { mock } from 'react-native-mock';

const user = mock({
  id: 1,
  name: 'John Doe',
  email: 'johndoe@example.com',
});

Creating Mock Data

React Native Mock also includes a utility function for generating mock data in bulk. The mockData function takes an object that defines the shape of the data you want to create, as well as the number of objects you want to create.

import { mockData } from 'react-native-mock';

const users = mockData({
  id: Number,
  name: String,
  email: String,
}, 10);

Mocking a Function

In some cases, you may want to mock a function that returns data from an API or server. To do this with React Native Mock, you can use the getMockFunction function.

import { getMockFunction } from 'react-native-mock';

const getUser = getMockFunction(
  { id: Number },
  { name: String, email: String }
);

const user = await getUser(1); // { name: 'John Doe', email: 'johndoe@example.com }

Mocking a Promise

Finally, if the data you want to mock is returned asynchronously using a Promise, you can use the getMockPromise function.

import { getMockPromise } from 'react-native-mock';

const getUser = getMockPromise(
  { id: Number },
  { name: String, email: String }
);

const user = await getUser(1); // { name: 'John Doe', email: 'johndoe@example.com }
