fetchwrap

fetch mocking framework

Usage

import fetchwrap from 'fetchwrap';

describe('test', () => {
  it('should mock fetch', () {
    const payload = { foo: 'bar' };
    fetchwrap.mock('GET', '/foo', payload);
      fetch('/foo')
        .then(response => response.json())
        .then(response => expect(response).toEqual(payload));
  });
});

API

mock(method, pattern, [response])

Registers a mock for a given method/pattern.

• method can be any of 'DELETE', 'GET', 'HEAD', 'OPTIONS', 'POST', 'PUT', 'PATCH'
• pattern can exactly match a URL or can use a regular expression string, (e.g., "/foo*").
• response is indicative of what you will be sent back as payload. It can take an integer status code or an object representing the response. If the object has a status member, that will be pulled out of the payload

If multiple mocks are registered for the same method/pattern, the mocks will be called in order of registration, with the final matching mock called for subsequent matches.

delete(pattern, [response]), get(pattern, [response]), head(pattern, [response]), options(pattern, [response]), patch(pattern, [response]), post(pattern, [response]), put(pattern, [response])

Convenience methods which call mock with the appropriate method
