node-mocks-http

Mock 'http' objects for testing Express routing functions, but could be used for testing any Node.js web server applications that have code that requires mockups of the request and response objects.

Installation

This project is available as a NPM package.

$ npm install node-mocks-http

After installing the package include the following in your test files:

var httpMocks = require('node-mocks-http');

Usage

Suppose you have the following Express route:

app.get('/user/:id', routeHandler);

And you have created a function to handle that route's call:

var routeHandler = function( request, response ) { ... };

You can easily test the routeHandler function with some code like this using the testing framework of your choice:

exports['routeHandler - Simple testing'] = function(test) {

    var request  = httpMocks.createRequest({
        method: 'GET',
        url: '/user/42',
        params: {
          id: 42
        }
    });

    var response = httpMocks.createResponse();

    routeHandler(request, response);

    var data = JSON.parse( response._getData() );
    test.equal("Bob Dog", data.name);
    test.equal(42, data.age);
    test.equal("bob@dog.com", data.email);

    test.equal(200, response.statusCode );
    test.ok( response._isEndCalled());
    test.ok( response._isJSON());
    test.ok( response._isUTF8());

    test.done();

};

Design Decisions

We wanted some simple mocks without a large framework.

We also wanted the mocks to act like the original framework being mocked, but allow for setting of values before calling and inspecting of values after calling.

For Developers

We are looking for more volunteers to bring value to this project, including the creation of more objects from the HTTP module.

This project doesn't address all features that must be mocked, but it is a good start. Feel free to send pull requests, and a member of the team will be timely in merging them.

After making any changes, please verify your works.

Running Tests

Install jshint globally.

npm install -g jshint

Navigate to the project folder and run npm install to install the project's dependencies.

Then simply run the tests.

./run-tests

Release Notes

Most releases fix bugs with our mocks or add features similar to the actual Request and Response objects offered by Node.js and extended by Express.
