A Jest mock for superagent. Place in your __mocks__ directory.

superagent.js

'use strict';

var mockDelay;
var mockError;
var mockResponse = {
    status: function () {
        return 200;
    },
    ok: true,
    get: jest.genMockFunction(),
    toError: jest.genMockFunction()
};

var Request = {
    post: jest.genMockFunction().mockReturnThis(),
    get: jest.genMockFunction().mockReturnThis(),
    send: jest.genMockFunction().mockReturnThis(),
    query: jest.genMockFunction().mockReturnThis(),
    field: jest.genMockFunction().mockReturnThis(),
    set: jest.genMockFunction().mockReturnThis(),
    accept: jest.genMockFunction().mockReturnThis(),
    timeout: jest.genMockFunction().mockReturnThis(),
    end: jest.genMockFunction().mockImplementation(function (callback) {
        if (mockDelay) {
            this.delayTimer = setTimeout(callback, 0, mockError, mockResponse);

            return;
        }

        callback(mockError, mockResponse);
    }),

    __setMockDelay: function (boolValue) {
        mockDelay = boolValue;
    },
    __setMockResponse: function (mockRes) {
        mockResponse = mockRes;
    },
    __setMockError: function (mockErr) {
        mockError = mockErr;
    },
    __setMockResponseBody: function (body) {
        mockResponse.body = body;
    }
};

module.exports = Request;

Did an update to support es6 and the last version of jest
